BACKGROUND OF THE INVENTION The present invention is generally related to the field of orthodontics, and more specifically, the computer automatic development of orthodontic treatment plans and appliances. Orthodontics is a dental medicine Branches are mainly about the straightening of crooked teeth. Although there are many appliances that can be used by orthodontists to straighten teeth, the most common appliance is a brace. The appliance contains many devices such as brackets, bows, straps and 0-rings These devices are tedious and time consuming on the patient's teeth and must be treated multiple times by an orthodontist. Therefore, traditional orthodontics The treatment limits the patient capacity of the orthodontist and makes the orthodontic sound comparable. Before locking the bracket to the patient's teeth, it is usually necessary to make an appointment with the orthodontist, dentist, and / or X-ray room to obtain the disease X-rays and ridges of the teeth and jaw structure. At the initial consultation or later follow-up, an alginate model of the patient's teeth is usually made. This model provides correction for patients used by dentists Models of teeth are combined with X-rays and images to plan a treatment strategy. Orthodontists usually schedule one or more visits so that the stent can be locked to the patient's teeth. The treatment strategy is usually tried Error (trial-and-error) This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) ------------------- (Please read first (Notes on the back are to be filled in again.)

The description of the invention (r) will be described in detail below. Individual teeth and other parts can be split or separated in the model to be individually repositioned or removed from the digital model. After segmenting or separating parts, users often reposition teeth in the model in accordance with regulations or other instructions written by therapist. Alternatively, the user repositions one or more teeth based on visual appearance, or based on rules or calculations in a computer program. Once the user is satisfied, the final tooth configuration is added to the final digital data set (FDDS) (steps 1Q4). FDDS is used to produce appliances that move teeth in a specific order. First, the center of each tooth model can be adjusted in some ways. One method is the standard arch. The tooth model is then rotated until its root is in the proper upright position. Second, the tooth model is rotated about its upright axis into the proper orientation. The tooth model is then viewed from the side and moved vertically to its upright position. Finally, the dental arches are put together and the tooth model is moved slightly to ensure that the upper and lower dental arches can properly mesh with each other. The upper and lower dental arches are intermeshing using the collision detection process so that the contact points of the teeth are highlighted. According to D I S S and F D D S, a plurality of intermediate digital data sets (I N T D D S s) are defined to conform to the incremental adjustment device (step 106). Finally, a set of incremental position adjustment devices is generated based on INTDDSs and FDDS (step 108). In step 102, the patient's teeth can be scanned or imaged with X-rays, 3D X-rays, computer-assisted tomography or data sets, or magnetic resonance imaging, or other. The methods of digitizing these traditional images to produce useful data sets are well known and described in patent and medical articles. However, conventional techniques, such as Sanders Philadelphia, 1969, are applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm). ---- (Please read the precautions on the back before filling in ϋ 订 Order --------- Sign 480166 A7 B7 V.

After obtaining the dental casting, the insert is scanned by a scanner, such as a non-contact laser or destructive scanner, or a contact scanner, A digital scan is performed to generate the IDDS. The data set generated by the scanner can be represented in any digital form to ensure compatibility with the software used to manipulate the image represented by the data, as described in detail below. General technology, and laser scanning technology used to generate digital models, for example, Xu Yan in US Patent No. 5,605,459, the entire specification of which is incorporated herein by reference. Appropriate scanners include many scope acquisition bar System, usually based on whether the acquisition process needs to be scanned in three dimensions Parts are classified by contact. Some contact scanners use probes with multiple translational and / or rotational degrees of freedom. Computer-readable representations of sample objects (ie, digits) are recorded by the probe entity being pulled across the surface of the sample Generated by movement. Traditional non-contact scanners include reflective and transmissive systems. Many reflective systems are in use, and some use non-optical energy sources such as microwave radars or sensors. Others use light energy. Non-contact systems that use reflected light energy usually include special instruments that perform some measurement technique (such as image thunder, triangulation, and interferometry.) A non-contact scanner is an optical, reflective scan Scanners, such as laser scanners. Non-contact scanners like this are non-destructive (alas, do not damage the sample object), usually have a high resolution and can be obtained in a short time Scans an object.

The non-contact and contact scanner can also include a step-by-step color camera with a color scan function, with tools to obtain samples in digital format Color display of objects. The importance of this function not only obtains the shape of the sample object, but also its color, which will be discussed below. Other scanners, such as the CSS-1000 soil-splitting type scanner produced by Capture Geometry lnside (CGI), Minneapolis, Minnesota, provide more detailed information on patients' teeth than the general range of scanners And correct information. Beyond that, the destructive scanner can acquire images from areas that are hidden or obscured by the range acquisition scanner and cannot be scanned. The CSS-100D scanner collects image data of an object. The method is to repeatedly mill thin slices from the object and sequentially scan the surface of the thin sheet to form a sequence of 2D image slices. Nowhere on the surface will be hidden by the scanner. The image processing software combines the data of each sheet to form a data set representing the object, which is then transformed into a digital representation of the surface of the object, which will be described below. Destructive scanners can be combined with laser scanners to make digital models of patient teeth. For example, a laser scanner can be used to create a low-resolution image of the patient's upper and lower dental arches combined with the patient's wax bite, as described below. A destructive scanner is then used to form a high-resolution image of the dental arch. The data obtained by the laser scanner shows the relationship between the patient's upper and lower teeth, which can then be used to correlate the image produced by the destructive scanner with its derived digital model.

Description of the invention (#) 觞 Model formed Patient's initial digital data set (IDDS). In order to ensure that the casting has a consistent orientation during the entire damage scanning process, the operator of Satoshi Satoshi will place the casting in a ceramic material (potting material), such as Encase-It, an epoxy resin sold by CGI, and make the material under pressure. The hollow (PV) chamber is hardened to form a model. The ceramic material is placed in the pv chamber to ensure that it can harden quickly without air bubbles trapping in it. The color of the ceramic material can be selected to have a clear contrast with the casting material to ensure the clarity of the scanned object. The operator then mounts the model on a mounting plate and places the template in a destructive scanning system. In the destructive scanning system, a slicing mechanism ("cutter") is used to mill thin slices from the model (usually between 0,001 and 0.006 inches thick), and the positioning rod places the milled surface near the optical scanner Nearby. The optical scanner can be an off-the shelf device such as a flatbed scanner or a digital camera, which scans the surface to create a set of 2D image data sets representing the surface.

Description of the invention (9) The upper insert is scanned in a cylindrical shape. After scanning The data provides a medium-resolution digital model of the object, which is a combination of the patient's dental arches placed in the same relative structure in the mouth. The digital model is used to guide the two digital models (one for each dental arch).値) Configured template. More correctly, using software, such as Cyberware aligner software, each digital dental arch is then aligned with a pair of scans. Each model is then relative to each other and in the patient's mouth The dental arches are positioned uniformly. The scan can also be scanned separately to provide the second set of teeth information in the upper and lower dental arches. In particular, the plaster inserts provide a “positive” image of the patient ’s teeth. This export. And the wax pieces provide a "negative" image of the teeth A second or duplicate data set can be generated. The two sets of data are then matched to form a single data set that describes the patient's teeth with improved normality and accuracy. In addition to or in place of wax, Molds for casting gypsum castings can be used. Figure 2 is a flowchart of the procedure for generating a single set of data from the positive data set and the negative data set. First, scan data representing positive and negative solid tooth models are obtained (steps 300, 302 ). If the scanning data is obtained by a destructive scanning process, two digital 3D geometric models are constructed from the data, which will be described below (step 304). Scanning data obtained from the optical or range scanner system , Generally enough to generate geometric models. A geometric model is positioned to roughly match other models in the digital model space (steps 3 to 6), and an optimization procedure is performed to determine the best match between the models (steps 3G8).

Each pair of matching points is then combined into a single point to form a single data set. (Step 310). The combination of matching points can be based on many methods, for example, combining each pair The coordinates of the middle point are averaged and executed. Although laser scanning systems generally must perform three scans to adequately image the entire group of patients' teeth (each high and low casting has a high resolution scan and a Medium resolution (wax scan), the above-mentioned destructive scanning system can scan with a single wax, which is enough to image the entire group of teeth of the patient. Scan two when the wax is in position Castings to ensure that all important surfaces of the upper and lower teeth are obtained in a destructive scan. Scanning two castings can also provide a high-resolution image data set to maintain the relationship between the patient's upper and lower teeth. For the ceramic materials mentioned above, the color of the wax wax must be in sharp contrast with the color of the insert material. In order to ensure the clarity of the scanned image, the wax piece can be the same color as the ceramic material of the tooth insert, if there is no need to compare between the wax piece and the ceramic material. Or, the color of the wax piece can be compared with the tooth setting. The color of the pieces and the ceramic materials are very clear, if the images of the pieces are needed. The printing is performed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In addition to laser scanning and destructive scanning of the tooth surface to obtain 3D image data, The user wants to collect information about hidden emblems, such as the roots of the patient's teeth and the jawbone of the patient. This information is used to build a more complete model of the patient's teeth and more accurately show how the teeth respond to treatment. For example, the roots The information allows all tooth surfaces, not just the crowns, to be modeled, and then the relationships between the crowns and roots during movement are simulated. . The patient's jaw and gum information also makes the teeth move during treatment. 1 2- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 480166 A7 __B7_ V. Description of the invention (U) More accurate models are available. For example, X-rays of a patient's jawbone can help confirm glued teeth, and MRI can provide information about the patient's gum tissue density. Furthermore, the relationship between the patient's teeth and other craniums , So that the teeth are aligned correctly in each treatment step relative to the rest of the head. These hidden emblem data can be collected from many sources, such as 2D and 3DX light strip systems, CT scanners, and magnetic resonance imaging (hmi) Article. This information is used to make the hidden emblem visible in the tooth model, which will be described in more detail below. Orthodontic treatment plans for developing patients include operating IDDS on a computer or workstation with appropriate graphical user interface (GUI) and software to view and modify images. The pending software will be described in detail later. However, dental flotation devices with incrementally different geometries can be produced by non-computer-assisted technology. For example, a plaster insert as described above can be cut with a knife, saw, or other cutting tool so that the individual teeth can be repositioned in the insert. Disconnected teeth can then be held in place by soft wax or soft material, and multiple interdental tooth configurations can be made using modified stone bud inserts for this patient's teeth. Different configurations, using pressure and vacuum forming techniques, can be used to make multiple appliances in groups. The procedure for creating a 3D surface model of a tooth is discussed below. Many types of scanning data, such as those obtained by optical scanning systems, can provide 3D geometric models of teeth (such as triangular surface spray tables) during scanning. Other scanning technologies, such as the above-mentioned destructive scanning technology, provide information in the form of volume element H voxels, which can be converted into a digital geometric model of the tooth surface. -1 3- This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) ------------- i (Please read the precautions on the back before filling out the order- ------- Printed by the Consumer Property Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 480166 A7 __B7_ V. Description of the invention (P) Please read the notes on the back first. Figure 3 is a surface combination of voxel image data. Flowchart of the procedure. This method includes receiving image data from the destructive scanner (step 4 () 0), processing the data to isolate the modeled object (step 401), and applying the traditional `` forward cube march '' Cubes " technology to create the surface of the object (step 402). Each set of image data can include images of multiple dental inserts, or dental castings and other "annoying" objects such as bubbles in ceramic materials Image. This system is based on the 8-bit grayscale image value of the voxel, and assigns a unit value of a binary value (for example, "0" is black and "1 π is white) to each voxel to identify the image. Each object. Then, the same unit-ary binary values will be assigned next to each other. The elements are connected. Each group of connected voxels represents an object in the image. Then, except for the dental inserts of interest, this system obscures all object images and isolates the tooth casting to be modeled. This system Pass the data through a low-passf filter to remove the sounds from the obscured image data. The printing of the photocopying by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is very sharp in the neighborhood. The teeth are pointed and weave together. The tooth difference has a fixed group. The word value is a value system and the value is a number-order element image. The tooth image is distinguished from gray, and the body shadow is the same as or above the tooth shadow. After the element is colored, the value of the body and the face are separated from each other. The value of the image is the same as that of the material, and the side has a shadow image. The circle with reflection is surrounded by 4 materials. However, the value of the package can be considered as the ng technique, the phase limit, the material and the block in the tangible acting hi technology industry. From rc, choose a table material, square ma. Choose a porcelain value standing block. It is known that the pottery statue is fixed in the body, and the middle part of the tooth is set in the shadow.

This calculation can correctly locate the surface between two voxels. The method is to determine the difference between the limit value of each voxel and the image value, and then place the surface at a corresponding distance from the center point of each voxel. In some implementations, after the forward cube calculation has been applied, the resulting meshing is smoothed to reduce the jaggedness of the tooth surface formed by the forward cube conversion (step 404). The traditional smoothing operation can be used, such as moving the vertices of each triangle to the average position connecting adjacent vertices to reduce the angle between the meshing triangles. Any other step is to smooth the meshing kill operation to remove data points and change the processing speed (step 406). The traditional kill operation recognizes pairs of triangles on almost the same plane and removes common vertices to combine each pair of confirmed triangles into a triangle. The killing operation used here also adds specific rules for orthodontics, which rely on the general characteristics of teeth and gums, as well as the general understanding of orthodontic appliances that will be used to implement the treatment plan. For example, orthodontics generally do not touch portions of the tooth surface adjacent to the tooth gap, so these tooth surfaces can be modeled less accurately than other parts of the tooth. The kill operation adds this knowledge by killing more heavily along the gum line. When, for example, a polymer-clad orthosis can be used to treat a patient's teeth, the calculation also kills it more heavily on the side of the tooth, and the orthosis usually only needs to be pushed vertically to the surface without killing on the top of the tooth. The orthosis must usually be formed here. A stack of solid clips. After the smoothing operation and the killing operation are performed, the error value is formed according to -1 5-This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm)

Description of the invention ((4) The difference between the meshing and the original meshing or the original data is calculated (step 4 0 8), and the error is compared with an acceptable limit value (step 4 10). If the error does not exceed If the value is accepted, the smoothing and killing operations are applied to the chew once again. The last set of meshing data that meets the threshold value is stored as a tooth model (step 4 12).

Other local anatomy data structures, such as the wingline data structure, can also be used. When viewing a three-dimensional image of a patient's jaw, including teeth, gums, and other mouth groups, in the first step, the user usually eliminates image manipulations and instruments to finally produce unnecessary structures. These unnecessary parts of the model can be removed using the eraser tool to remove the solid model (step 508). This tool is represented by a drawing box. The volume (size, position, and orientation of the box) to be eliminated is set by the user using the GUI. Generally, the unnecessary parts include the irrelevant gum area and the base of the original scanned casting. Other applications of this tool are to facilitate extraction of teeth and " shaving down " This is necessary when the final position of the tooth to be moved in the jaw requires extra space. The treatment professional can choose which tooth is scraped and which tooth is extracted. When only a small amount of space is needed, scrape the teeth to keep the patient's teeth. Generally, extraction and scraping are used in the treatment plan only when the actual patient's teeth are extracted and scraped before the repositioning begins. Removing unnecessary or unnecessary parts of the model increases processing speed and enhances visual display. Unnecessary parts include parts that are not required to make a dental repositioner. The elimination of unnecessary parts reduces the complexity and size of the digital data set, thus speeding up the manipulation of the data set and other functions. -17- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm),

Description of the Invention (4) After the user positions and resizes the eraser tool and instructs the software to eliminate unnecessary parts, all triangles set by the user in the box are removed, and the boundary triangles are modified to be smooth linear Boundary. The software removes all triangles in the box and cuts all triangles that cross the boundary. This requires the creation of new vertices at the boundaries of the box. The holes made in the model on the surface of the box are made using the new vertices. It is triangular and closed. In another embodiment, the computer automatically simplifies the digital model by performing the above-mentioned user-oriented functions. The computer applies knowledge of orthodontics, such as about determining the parts of the digital model that are not necessary for image manipulation. A jagged shape The tool is used to form each tooth (or a group of teeth) to be moved (step 510). This tool will scan the image Cut into individual graphic parts (step 512) so that the software can move teeth or other parts independently of the rest of the model. High-resolution and low-resolution parts are matched (step 514), and the parts are placed in In its final position (step 516). In one embodiment, a jagged tool is formed to use two cubic B-curves lying in space, which can be confined to a parallel plane and can be opened or closed. A set of lines connects the two Curve, and displays the user's general cutting path. The user can edit the control points on the cubic B-curve, the thickness of the sawtooth cutting tool, and the eraser tool used, which will be described below. In another embodiment, The teeth are separated using a serrated tool as a "coring device. The teeth are cut with an upright serrated cutter as described above.

Description of the invention (彳) The preview feature can also be provided in the software. The preview emblem visually shows a jagged cut to cut two surfaces of two opposite edges. This allows the user to consider the final cut before applying it to the model data set. Use After completing all the desired cutting operations with a jagged tool, multiple solid bodies are generated. However, at this point, the software has not yet determined which triangles of the four-sided data structure belong to those parts. The software selects a random starting point in the data structure and starts with Use neighboring information to traverse the data structure to find all the triangles fixed to each other, and confirm the individual pieces. This process starts with the triangle that has not been determined by the pieces, and iterates. Once the entire data structure has been scanned After that, all the parts have been confirmed. For users, all changes of the high-resolution model also occur in the low-resolution model, and vice versa. However, there is not a one-to-one relationship between different resolution models. Therefore, the computer will match the high-resolution and low-resolution parts only within the bounds as possible. The system can optionally include a segmented sub-system, which can automatically and semi-automatically segment the 3D tooth model into individual tooth models. The segmented sub-system is preferably implemented by one or more computer program programs executed by a segmentation program. In other implementations, the segmentation procedure can be applied to 3D volume data or 3D surface meshing. The segmentation procedure can use traditional feature detection techniques to trim to discover the characteristics of teeth. For example, the calculation of feature detection is generally used In the image, the emblems that are separated from each other are in different colors or shades of gray. The emblems to be detected are usually separated from each other in space. However, 2D or 3D gypsum insert images need to be detected (for example, individual teeth and gum group-2 0-This paper size applies to China National Standard (CNS) A4 (210 X 297 mm)- ------------.

Description of the Invention (^) Weaving) have the same color (white), and some special emblems such as individual teeth and surrounding gum tissue have no space isolation .. Segmentation procedures can be performed to use any of many Feature detection technology, and the best combination of technologies to increase the accuracy of the emblem identification. A pending detection technology uses color analysis to distinguish objects based on color changes. Color analysis can be used when individual teeth are separated by a gap. Its size is large enough to fill ceramic materials. Because the dental inserts and ceramic materials have contrasting colors, these teeth appear in the model as white areas separated by thin black bands. Other feature detection techniques use shape analysis to Do n’t use some special teeth, such as tooth gums. Usually, the tooth surface is smooth, and the gum surface is textured, and the teeth and gums usually form ridges where they meet. Using shape analysis to detect these teeth can help distinguish between teeth and Gum. Shape analysis can also detect individual teeth, such as finding the largest object in a 3D image, or identifying the molars of the molars, which are divided into four shapes and arranged in a pattern. The teeth detection algorithm will describe The following is a special emblem detection technology using known cases, using a database of special 3D images or statistical information matched by traditional image and graphic matching and data matching technologies. One such technology is known as " Maximuffi a Postriori (MAP) uses the previous image to model the pixel values corresponding to the type (level) of individual objects, and has a normal distribution (Gaussian) whose parameters (mean mean and variance) are selected by the experiment and independent Random variables. For each level, the histogram of the bar graph is made according to the Gaussian distribution of the specific average and variance. The previous image provides each Pixels and each level, the pixel is the probability of falling below that level, it reflects the relative frequency of each level-2 1- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm)- ------------------- Order --------- Line- (Please read the notes on the back before filling in 480166 A7 B7 V. Description of the invention (- 〇) rate. Apply the Bayes rule to each level, the pixel values in the input image are determined by the previous probability rate, and then scaled by the distribution function. The probability of posteriori at each level. The Maxiffluu a posteriori (MAp) method then selects the number of pixels for each pixel, and uses the highest possible posteriori rate as the segmented output. Other feature detection techniques use automatic tooth detection. Teeth are stippled protrusions on the chewing surface of the teeth. In one implementation, tooth detection is performed in two stages: (1) " detection " stage, where ~ groups of points on the teeth are determined as candidates for tooth position; and (2) " rejection " stage Among them, one of the candidate points was rejected when it failed to meet the specifications of Phosphorus. The procedure of the " detection " stage is shown in Figure 6A. In the detection phase, the possible tooth is regarded as an "island" of the tooth surface, and the candidate tooth is at the highest point on the island. The "highest" is measured relative to the coordinate system of the model. If the measurement is performed after the cutting phase of the treatment, it can simply be obtained relative to the individual coordinate system of each tooth. All possible tooth-fu groups are determined by finding the local highest point on all the flounder models. The local highest point is within a certain distance from the top of the model's bounding box. First, the highest point on the model becomes the ~ th candidate tooth. A plane passes through this point, and the height is changed perpendicular to a point (the direction of the quantity. This plane is then lowered along the Z axis by a small predetermined distance. Second, all are connected to the teeth and above the plane, and on some soil junctions The vertices on the pieces are connected to the candidate tooth fu as the tooth fu. This step is also known as, 丨 $ (flood filly) " steps. From each candidate tooth fu point, outward, and overflow " It is executed in this way to make every ~ vertex on the model correspond to -22- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ----------- --i (Please read the notes on the back before filling

After the overflow step is completed, each vertex on the model is reviewed. Any vertices that are above the plane and have not been visited by the full step are added to the list of candidate teeth. These procedures are repeated until the plane has moved a certain distance. Although this iterative method takes more time to find than the highest point in the region, the pop-up method can result in a shorter candidate list. Because the plane is lowered a certain distance at each step, the highest point in a small area that may be generated is skipped due to the sound data. After the detection phase, the teeth detection calculation proceeds to the " rejection " phase. One of the "reject" phases, the procedure is shown in Figure 6B. In this step, the local geometries of each candidate tooth are analyzed to determine whether they have "non-tooth futian". Candidates showing the "non-dental fu emblem" are removed from the list of candidate dents. Many specifications can be used to identify " non-dental fu special features ". According to the experiment, the candidate peripheries have a The local curvature is used to determine whether the candidate tooth is shown to have "non-tooth teeth". As shown in Figure 6B, the local curvature of the surface around the candidate tooth is roughly estimated and then analyzed to determine whether it is $ large ( Very sharp surface) or too small (very flat surface). At this time, the candidate teeth are removed from the list of candidate teeth. Use conservative values as the minimum and maximum curvature to ensure that the true teeth are not Will be wrongly rejected. In another test, the measure of smoothness is calculated based on the average standard of the area around the candidate tooth. If the average vertical line (normal) deviates from the vertical line of the tooth more than a certain amount, the candidate tooth is rejected. In one embodiment, -23- This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) ------------- I (Please read the precautions on the back before Fill out the order Printed by the Ministry of Intellectual Property Bureau's Consumer Cooperatives 480166 A7 B7_ V. Description of the invention (") The vertical vector N deviates from the vertical line CN of the tooth and is estimated by the following formula: Deviation = absolute value (N-CN) When there is no deviation, its value It is zero. When N is perpendicular to CN, the value is 1. For manual assistance and automatic segmentation technology, if a solid tooth model is scanned and marked, the clinician can simplify the tooth recognition process. During scanning, These marks become part of the digital tooth model. The types of marks that clinicians may use include marks that identify the axis of rotation of the tooth, marks that identify the main axis of the tooth (such as a line marked on the edge of the tooth), and marks that identify the boundaries between teeth. The mark identifying the axis of rotation of the teeth is often used to limit how the teeth can be rotated during the treatment. Clinicians may also want to paint a solid model of the tooth to help segment the inferior tooth from the digital tooth model. The strip can be arbitrarily added to the root and hidden surface to the tooth model, so that the movement of the teeth during the treatment can be completely and correctly simulated. In an implementation example, this information is automatically added using many data sources, without manual assistance, manual assistance semi-automatic, or full human operation. In some implementation examples, 2D and 3D imaging strips are like X-ray strips Systems, computerized tomography (CT) scanners, and magnetic resonance interference bars (MRI) are used to collect information on the roots of a patient's teeth. For example, X-ray images taken on many different planes of the teeth can be used to construct 3D model of the root of the tooth. The information of the root of the tooth can be obtained from the visual inspection of the X-ray image and the application of the computer to perform the special logo recognition calculation into the X-ray data. Add roots to the tooth model.

Description of Invention (d) The 3D data was extracted and used to register the roots into the tooth model. Like the roots, these markers can be extracted manually or calculated using special detection algorithms. Another way to add roots and hidden surfaces is to model the general root and crown shape, and modify the digital model of each tooth to include the root and hidden surfaces that are consistent with the general shape. This method assumes that the roots and hidden surfaces of each tooth of the patient are of ordinary shape. The geometric model of each general shape is obtained from the electronic database of general root and crown models before tooth analysis of a specific patient begins. In order to complete the individual tooth model, the general root and crown models are added to the individual tooth model application. Another way to add roots and hide the surface is to extrapolate the 3D tooth model and include these features based on the observation characteristics of the tooth surface. For example, this system can use the curvature of a specific molar between the tip of the tooth and the gum line to predict the shape of the heel of the molar. In other implementations, X-ray and CT scan data of the patient's teeth are used to provide extrapolation comparison points for the patient's roots and hidden surfaces. General root and crown shape models can also be used to provide extrapolation comparison points for roots and hidden surfaces. This system can also add "movie" waiting, and the user can use the "movie" waiting at any point to show the movement of the movement from the beginning to the target state. This is to view the entire component during the treatment process The mobile is very helpful. As mentioned above, the user interface suitable for component identification is a 3D interactive graphical user interface (GUI). The 3D GUI is also used for component control-25- This paper size applies China National Standard (CNS) A4 Specification (210 X 297 mm) -------------- · I (Please read the precautions on the back before filling out the order -------- -Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 480166 A7 B7 V. Invention Description (4) is very advantageous. This interface provides instant and visual interaction between the treatment professional or the user and the digital model component. Such 3 The dimensional GUI also provides advantages to the interface, so that only low-level instructions can be used to instruct the computer to operate specific parts. In other words, the GUI used for operation is in many ways more than one only accepts instructions, such as the only kind: " "Move this part 0.1 mm to the right" interface is better. This low-level Instructions are useful for fine-tuning, but if they are the only interface, the process of piecewise operation will become tedious and time-consuming interaction. Before or during the operation, one or more dental pieces can be toothed. The root model is used to zoom in. The tooth model is operated using the tooth root template, for example, when the impact of the teeth below the gum line is very worried. These template models, for example, contain X-ray digital information of the patient's teeth The software can also add annotations to the data set, which includes the serial number of the text and / or device. The annotation can be added in intaglio (that is, it can be a 3-D geometry), so it will be displayed as a printed model.

The accessory viewer application is executed by a computer program installed on the accessory computer of the clinician's office. The viewer program is downloaded from the data file of the remote host, such as a File Transfer Protocol (FTP) server maintained by the treatment plan designer. It can be directly connected or accessed via a computer network, such as the Internet. The viewer program uses the downloaded file to graphically present the treatment plan to the treating clinician. The viewer program can also be used by the treatment plan designer to view images of the patient's teeth on the host side. Figure 6 shows the procedure for generating 3D images of many orthodontic views, which can be generated after the patient's teeth have been digitally obtained and modeled.
