Description

[0001] The present invention relates to a method of manufacturing a surgical guide for an implant,

The present invention relates to a surgical guide manufacturing method for an implant surgical operation. More particularly, the present invention relates to a surgical guide for implant surgery, which allows a patient to perform a bone and computer tomography at one time at a hospital, And a manufacturing method thereof.

In conventional dental implants, the success or failure of surgery is heavily dependent on the experience and proficiency of the dental surgeon. The dental surgeon determines the type, number, location, implant angle, and implant depth of the implants, and these decisions can vary depending on the experience and proficiency of the surgeon. Furthermore, even if the above conditions of the dental implant are determined, it is very difficult for the conditions to be equally implemented in the actual surgical procedure. This is because, even if the operation is performed by the same operation, the result of the operation can be changed every time. Therefore, the condition and proficiency of surgery can be a very important factor.

A variety of dental instruments have been developed to assist with this, one of which is the surgical guide. The surgical guide for a dental implant includes a guide body negatively corresponding to an extracted mouth structure of a patient, and a hole is formed in the guide body for guiding a position and an installation angle of the implant. Because the surgery is performed by drilling, punching, and placing for the implant based on the hole of the guide body, it is possible to perform the implant operation as it is at the initial designed placement position and the angle of implantation, and reliance on the surgical skill can be reduced.

However, the process of making a conventional surgical guide is very complicated, and practically, it is impossible to perform all the procedures independently of the surgery alone. Specifically, when the patient first visits the clinic, the user turns the bone structure on the oral cavity and then returns to the hospital. The hospital builds a radiation guide body for the surgical guide based on the patient's oral cavity pattern, (CBCT) or computed tomography (CT) and then designing the position and angle of the implants through the combined structures. The operation of the surgical guide according to the designed conditions or the formation of the guide hole in the radiation guide body is commissioned by a third party specialist company. This is because the stereoscopic structure manufacturing facility for producing the surgical guide is very expensive and can not be owned by the individual person of the surgery, and because it requires expert knowledge, the equipment can not be effectively used. In practice, it takes at least 10 days for the surgeon to produce the 3D guide body, to deliver the guide body to the professional manufacturer in postal or parcels along with the surgical guide design conditions, to receive the surgical guide from the professional manufacturer, If the surgical guide does not meet the design requirements or wants to change the condition, there is a need to wait a dozen days again.

In order to solve the above problems, the present invention has proposed Patent Application No. 10-2011-0011813, but since the radiation guide is still used, the patient has a long treatment period and has to visit the hospital more than once. That is, the conventional surgical guide manufacturing method as described above requires the operation of creating a positive model for floating the mouth shape of a patient and the guide body by using the positive model, The patient has to visit the hospital more than 2 times, which is very inconvenient, and since the operation guide production period is long, the treatment period becomes longer and the suffering of the patient becomes longer.

In conventional dental implants, the success or failure of surgery is heavily dependent on the experience and proficiency of the dental surgeon. The dental surgeon determines the type, number, location, implant angle, and implant depth of the implants, and these decisions can vary depending on the experience and proficiency of the surgeon.

The surgical guide for a dental implant includes a guide body negatively corresponding to an extracted mouth structure of a patient, and a hole is formed in the guide body for guiding a position and an installation angle of the implant. Because the surgery is performed by drilling, punching, and placing for the implant based on the hole of the guide body, it is possible to perform the implant operation as it is at the initial designed placement position and the angle of implantation, and reliance on the surgical skill can be reduced.

However, the process of making a conventional surgical guide is very complicated, and practically, it is impossible to perform all the procedures independently of the surgery alone. Specifically, when the patient first visits the clinic, the user turns the bone structure on the oral cavity and then returns to the hospital. The hospital builds a radiation guide body for the surgical guide based on the patient's oral cavity pattern, (CBCT) or computed tomography (CT) and then designing the position and angle of the implants through the combined structures.

That is, the conventional surgical guide manufacturing method as described above requires the operation of creating a positive model for floating the mouth shape of a patient and the guide body by using the positive model, The patient has to visit the hospital more than 2 times, which is very inconvenient, and since the operation guide production period is long, the treatment period becomes longer and the suffering of the patient becomes longer.

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a method for designing a bone structure, an implant position and an angle of an oral cavity of a patient when a patient first visits, a CBCT (Cone Beam Computed Tomography) ) In order to shorten the treatment period of the patient. That is, the present invention reduces the number of visits to a patient because the placement position and the implantation angle of the implant can be calculated without separately preparing a radiation guide. The present invention can reduce the number of patient visits by performing CBCT (Cone Beam Computed Tomography) or CT (Computed Tomography) for designing the position and angle of the oral structure of the patient and the implant when the patient first visits, Therefore, it is possible to shorten the preparation time of the surgical guide, thereby shortening the treatment period of the patient.

(a) is a step of floating the patient's oral structure pattern to make the positive model 100 corresponding to the extracted oral structure of the patient. (a) is a step of making a model of the oral structure of the patient when the patient visits. The positive model 100 may be formed using the gypsum material of the patient or the like and may be formed in a structure corresponding to the extracted oral structure of the patient, So that it can be manufactured without difficulty.

(b) is a step of applying the impression material 10 to the plate 200 for computer tomography, inserting the impression material 10 into a patient's mouth, and performing CBCT or CT to measure a position at which the implant is to be implanted.

The plate 200 for a computer tomography is composed of a body 210, a reference point 220 and a first fixing hole 230, and it is possible to measure a position where an implant is inserted immediately when a patient visits the first hospital, (Treatment period) of the patient. The plate for computer tomography 200 includes a U-shaped body 210 as a plate to be inserted into a tooth during computed tomography to measure a position at which the implant is to be inserted, A reference point 220 on which a line connected to the other two points is perpendicular to each other with respect to one point and an impression material 10 floating on a tooth of a tooth are fixed to the upper surface of the body 210 And a first fixing hole 230 having a plurality of holes at one side thereof.

The body 210 is in the form of a U-shaped plate, which is a tooth-pressed plate during computed tomography to measure the position at which the implant is to be inserted. That is, the body 210 is a U-shaped plate inserted into the oral cavity so that the teeth can be easily stitched. The body 210 may be a radiopaque plate, and various materials may be used as long as it is inserted into the oral cavity to measure a position at which the implant is inserted during a CT scan. Also, the body 210 may be made in various thicknesses, but is preferably formed in a thickness of 2 mm. And a handle 215 coupled to an outer curvature portion of the 'U' shaped body 210. The handle 215 is convenient for a practitioner to use. In other words, the practitioner can easily insert the body 210 into the mouth of the patient by pulling the knob 215 coupled to the body 210 and remove the body.

The reference point 220 has three points on one side of the upper surface of the body 210, and lines connecting the remaining two points are perpendicular to each other. The reference point 220 is a reference point for measuring a position at which the implant is to be inserted during a CT, and the other two points are located on the x-axis and the y-axis. Therefore, the position at which the implant is to be inserted with reference to the reference point 220 is calculated after computed tomography. The reference point 220 can be readily identified in a computed tomography using a radiopaque material.

The first fixing hole 230 is a hole in which a plurality of holes are formed in one side of the top surface of the body 210 so that the impression material 10 floating on the tooth pattern can be fixed. The first fixing hole 230 is pierced at a distance from the auxiliary reference point 225 so as not to interfere with the auxiliary reference point 225 described later. The impression material 10 is easily discharged from the first fixing hole 230 by the pressure applied by the patient to impression the impression material 10 and the impression material 10 discharged to the first fixing hole 230 is discharged to the inside of the patient's mouth And the impression materials 10 fixed to or discharged from the body 210 are coupled to each other by the components (tongue, teeth, etc.) to form a nail head shape. It can be done. That is, the first fixing hole 230 helps the impression material 10 to be stably fixed to the body 210.

The present invention further includes a supplementary reference point 225 in which a plurality of points are formed in a 'U' shape on one side of the upper surface of the body 210 in order to more precisely measure the position of the implant, . That is, the auxiliary reference point 225 is a point for measuring a more accurate implant treatment position by assisting the reference point 220. The position of the auxiliary reference point 225 where the implant is to be inserted more precisely with reference to the reference point 220 is calculated after the computed tomography. The secondary reference point 225 can be readily identified during computed tomography using a radiopaque material.

In addition, the present invention can be applied to a drill device 400 used for manufacturing a surgical guide 300, which is drilled on one side of an upper surface having an inner curvature portion of a body 210, Hole 235, as shown in FIG. The second fixing hole 235 is formed in the hole 235 so that the body 210 can be fixed to the drill apparatus 400 that is coupled to the positive model 100, to be. The second fixing hole 235 is formed in the upper surface of the inner curvature (a portion having a relatively small radius of curvature) of the U-shaped body 210, so that the second fixing hole 235 can be easily fixed to the drill 400.
