The whole contents of the constitution shown in the following examples are not limited to the solution of the utility model described in the claims.

Referring to fig. 1 to 3, the present embodiment provides a bendable implant, comprising a fixing portion, a base portion and a neck portion, wherein the fixing portion is configured to extend into and be fixed inside bone tissue of a human body, and in particular, the fixing portion is provided with external threads and is screwed into jawbone of the human body; the abutment part is exposed out of the oral cavity of the human body at the position where the teeth are needed to be filled and is used for bearing and fixing the dental crowns, so that the denture is stably supported.

The neck is integrated between the fixed part and the base part, so as to play a role in connection, and here, the fixed part, the base part and the neck are integrally formed, and the fixed part is only required to be embedded and fixed in human bone tissue during operation, so that the base part can be fixed, the operation steps and operation time are reduced, and the pain of a patient is relieved.

Meanwhile, the neck can be bent by stress, the angle of the base table part relative to the fixed part can be adjusted by bending the neck, when the angle of the implanted fixed part is inclined, the angle of the base table part can be adjusted according to the biting direction of a patient, and the neck is provided with certain rigidity after bending, so that the base table part can bear the biting strength of a human body along with the bending of the neck relative to the fixed part, namely the bendable implant has better biting breaking strength after bending, the stability of the denture after installation can be ensured, and the aim of achieving the complete mouth immediate crown wearing operation is fulfilled.

It should be noted that the acting force applied to the neck portion by bending the neck portion should be greater than the acting force applied to the neck portion by the abutment portion when the human body is engaged, so as to avoid deformation of the neck portion due to the engaging force.

In the operation (the operation steps of the bendable implant are described in detail below), the arrangement is such that the angle adjustment of the abutment portion relative to the fixing portion can be realized through bending of the neck, the complex and high-cost operation of repairing and taking the mould through the multi-stage abutment is not needed, the operation time of a patient is reduced, the pain is reduced, and meanwhile, the operation complexity of a doctor is reduced.

In the embodiment, the fixing part, the base part and the neck part are made of titanium alloy materials and are integrally formed, so that the operation is simple, the number of matched tools is small, the fittings are small, and the cost is low. Specifically, the titanium alloy material has certain stretching property and enough anti-fatigue capability in mechanical strength, can be set as four-grade titanium or five-grade titanium, and is different in purity, and the higher the grade, the stronger the titanium and the better the stability.

Among them, the four-grade titanium and the five-grade titanium are materials commonly used for medium-high end implants, and can be compatible with human alveolar bones without any reaction. Can not cause injury to alveolar bone, is beneficial to promoting the combination of bone and implant, has better stability and is not easy to cause mechanical complications.

As shown in FIG. 2, the bending part of the neck is in a cylindrical shape, so that the neck can be bent at any angle of 360 degrees at one time, the azimuth angle of the abutment portion can be adjusted conveniently, and the diameter of the cross section of the cylinder is set to be 1.5-3 mm, so that the neck is convenient to bear force, and the abutment portion can be adjusted conveniently relative to the angle of the fixing portion.

In order to provide sufficient space for bending of the neck, the axial length L2 of the neck is set to 3-6 mm.

It will be appreciated that since the fixing portion, neck portion and abutment portion are coaxially arranged and connected in sequence, the axial length referred to herein is the extension direction of the fixing portion, neck portion and abutment portion.

Specifically, this implant of buckling sets up to five grades of titanium materials, simultaneously, the axial length L2 of neck sets up to 4 millimeters, and the diameter D1 of the bight of neck sets up to 1.8 millimeters, through the reasonable design to neck material and size, both can make the neck to atress buckle, can guarantee again that the neck still has stronger anti interlock intensity after the atress is buckled.

In some embodiments, the neck portion includes a screwing structure, the screwing structure is formed on the neck portion near the fixing portion, the screwing structure can be matched with a disassembling tool, when the neck portion is bent and stressed too much to cause breakage, the screwing structure can be operated through the disassembling tool, so that the broken fixing portion is taken out from human bone tissue, and operation safety is guaranteed. Here, the screwing structure may be a non-cylindrical structure.

The screwing structure comprises at least one tangent plane arranged on the side wall of the neck, and the disassembling tool can drive the screwing structure to rotate through the action of the tangent plane and the disassembling workpiece to realize disassembly and assembly.

Here, the screw-on structure is provided with four tangent planes to form outer four corners structure, make things convenient for extracting tool adaptation application of force.

Specifically, the cross section of the outer tetragonal structure is square, and the side length D4 is 2.15 cm.

Of course, the cross-sectional shape of the screw structure may coincide with the cross-sectional shape of the portion of the abutment portion remote from the neck portion, so that the removal tool is adapted at a plurality of places.

It will be appreciated that in connection with the above embodiments, the neck may comprise a first portion comprising a cylindrical body and a second portion forming a screw-on structure, the second portion of the neck being adapted to receive the fixing portion, and of course the neck may comprise a third portion adapted to receive the abutment portion. Here, the diameters of the base portion and the fixing portion are both larger than the diameter of the neck portion, so that the base portion and the fixing portion are not deformed when the neck portion is bent and stressed.

In order to ensure that the screwing structure does not affect the bending part of the neck and reduce the occupied space, the axial length of the screwing structure is set to be 1-2 mm.

In some preferred schemes, the axial length L1 of the base is set to be 6-7 mm, so that when the neck is bent, the fixing part is fixed with human bone tissue, the base part is required to be forced, the base part is designed to be long, the forcing point and the forcing direction are convenient to adjust, and the flexibility of angle adjustment is ensured.

Correspondingly, the axial length L3 of the fixing portion may be selected and adapted according to the actual situation of the bone tissue of the human body, which is not limited herein.

In addition, the fixing portion is provided with an external thread for screw-coupling with the bone tissue of the human body, and the diameter of the external thread decreases in a direction away from the neck portion, specifically, a region diameter D2 of the fixing portion near the neck portion is larger than a region diameter D3 of the fixing portion away from the neck portion. Therefore, the fixing part and the human bone tissue can be stably connected only by one-time perforation without perforating the human bone tissue for a plurality of times, the operation procedure is reduced, and the operation efficiency is improved.

The operation procedure of the bendable implant will be specifically described with reference to the above-described embodiments.
