Description

Two-stage surface treatment characteristics of stepless dual-use implants-gingival type and dental type

This creation is about artificial implants, using the roughness of the holes on the upper and lower surface treatments to meet the needs of gingival (Tissue level) implants or bone level (Bone level) implants. There are three self-tapping symmetrical three grooves under the body thread part, which improves the implants with only round-shaped threads in the past, which can more easily drill the hole to the depth required by the close implant, and then steplessly lock into the alveolar bone To a precise depth, to meet the needs of patients with different depths, effectively improve the efficiency of dental implants, improve the long-term fixation of the implant, and facilitate the physician to perform the surgery in response to the state of the clinical gingival bones and determine the depth of the implant. body.

The high success rate and popularity of artificial implants are now one of the preferred treatments for the dentist community to restore the function of patients with missing teeth.

The dentist chooses the appropriate artificial implant according to the clinical factors of the patient's oral structure, alveolar bone density, axial direction of the implant, the amount of occlusion space, and the height of the tooth of the patient. However, the appropriate abutment is selected clinically. It is often necessary to rely on the experience of the physician and prepare a large number of various implants for selection to have good results.

In the past, artificial implants often used round-shaped screw implants. According to the thickness of the jaw bone and the thickness of the gums, a gingival (Tissue level) implant or a bone level (Bone level) implant was selected, and the artificial implant was made of screw teeth. Lock into the jawbone and expose the upper end of the implant above the gum or bone The assembly of the inner hole provides the assembly of the abutment and the denture. The implant is locked into the gap between the threaded surface of the alveolar bone, and the proliferation of the alveolar bone is attached to the surface-treated implant to increase the artificial implant. Closeness to alveolar bone.

However, in the past, most artificial implants were whole implants, and a single surface treatment method could not be satisfied at the same time. The proliferation of tissue cells of alveolar bone and gingiva was different. Because it could not induce the maximization of the proliferation of alveolar bone and gingival tissue, the lost part The tightness of the artificial implants and the long-term fixation force of the implants cause the artificial implants to be unstable and may cause problems.

The above two different types of implants have their own application status and convenience and economy in artificial dental implants, but they have not been able to further innovate and integrate on the same implant, reducing clinical flexibility. This is now known The main problem of technology.

This creation provides a stepless dual-use artificial implant, which improves the complexity of the current need for a variety of artificial implants and alveolar femoral tissues. The single artificial implant can meet the gingival (Tissue level) implant or Dental implant requirements for bone level implants.

This creation is a stepless dual-use implant, including a body: the upper end of the body is provided with a concave assembly inner hole, the upper end of the inner hole is octagonal, and the outer surface of the upper part of the body is different through the upper and lower sections Rough surface treatment, the outer surface of the upper section has a surface roughness of 0.5 to 1.0 μm, and the outer surface of the lower section has a surface roughness of 1.2 to 4.0 μm; the lower part of the body is a self-tapping lock-in forming end, and the outer part of the lower part is a threaded part, The surface of the threaded part is roughened, and there are three self-tapping symmetrical three grooves under the threading part, which is convenient for self-tapping to lock the alveolar bone to a precise depth, and the cross-sectional size of the body tapers from the top to the bottom.

In this specification, the "surface roughness" refers to the arithmetic mean height of the surface Sa.

This creative stepless dual-use planting system uses different surface treatments on the upper and lower stages, so that the upper and lower surfaces each have a specific range of surface roughness. Using the shape and shape of the upper part of this stepless dual-use implant, The structural features can be applied to the dental implant needs of gingival implants or dentulous implants at the same time, and can also meet the proliferation requirements of cells of different tissues of alveolar bone and gingival, so that cells of different tissues can be attached to the surface-treated On the implant, fill the gap of the threaded surface of the implant locked into the alveolar bone to comprehensively improve the tightness of the stepless dual-use implant and the long-term fixing force of the implant, making the stepless dual-use implant more stable, It is more difficult to loosen, and can increase the closeness of the stepless dual-use implant and alveolar bone, and the clinical surgeon can control the implantation depth according to the state of the patient's mouth.

In this creative stepless dual-use implant, the stepless means that the implantation depth of the dual-use implant can allow the doctor to cooperate with the growth of the patient's gums, such as the width, height or thickness of the missing teeth. Continuous adjustment, that is, the doctor can adjust the implantation depth of the upper surface roughness area of the upper part of the body according to different oral soft and hard tissue conditions, so the upper surface roughness area of the upper part of the body can be regarded as a stepless lifting area. The height of this stepless lifting area is 0.5 mm to 2.5 mm (mm), and the height refers to the linear distance parallel to the axis of the implant.

In this creation, the outer part of the lower part of the stepless dual-use implant is a threaded part. The appearance of the threaded part can be treated by surface treatment. Through this surface treatment, the demand for tissue cell proliferation of the stepless dual-use implant and alveolar bone can be increased. The closeness of the stepless dual-purpose implant and the alveolar bone; under the threaded part, there are three self-tapping symmetrical three grooves. These three symmetrical grooves are parallel to the axis of the body and extend to the bottom of the body. This symmetry Three grooves, so that the stepless dual-use implant can self-tap to lock the alveolar bone to a precise depth. Compared with the implants with only round-shaped threads in the past, the precise depth before the implant is locked The burr hole allows the implant to have a more relaxed burr hole to the required depth of the implant. The symmetrical three grooves designed by this stepless dual-use implant are self-tapping to lock the alveolar bone to the precise depth, effectively improving the implant Teeth efficiency.

With the creation of a stepless dual-purpose implant, a dual-purpose implant that can be applied to both gingival and dentulous implants can be provided, which can effectively reduce the difficulty of selecting suitable implants, provide a more flexible and wide range of use, and improve tooth The doctor's work efficiency and use effect is good.

In the following, the structural features and usage effects of this creation will be described in detail based on the implementation examples shown in the drawings.
