Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): the utility model provides a biocompatible artificial tooth support, as shown in figure 1, contain base 1 and with base 1 interconnect's annular skeleton 2, base 1 and annular skeleton 2 are the arc and laminate each other with gum 9 and chin in the oral cavity respectively, be connected with between base 1 and the skeleton 2 a plurality ofly with 3 assorted snap rings 4 of natural tooth, fixed connection is on base 1 and skeleton 2 respectively at the both ends of snap ring 4, a plurality of snap rings 4 correspond the butt respectively on a plurality of natural teeth 3, be connected with two curved anchor strut 5 on the snap ring 4 respectively, anchor strut 5 laminates each other with the periphery of natural tooth 3 and the one end of keeping away from snap ring 4 and laminates each other with the up end of natural tooth 3. Consequently, snap ring 4 pastes the mode of tightly on 3 peripheries of nature tooth respectively through two anchor strut 5 and holds tightly with nature tooth 3 each other, and two anchor strut 5 support respectively tightly make snap ring 4 be difficult for the rotation of nature tooth 3 to break away from on nature tooth 3, and the firm in connection nature between snap ring 4 and the nature tooth 3 is better to make the denture support and have better firm in connection nature between the nature tooth 3.

As shown in fig. 1 and 2, the end of the reinforcing rod 5 that is attached to the natural tooth 3 is connected to a reinforcing plate 6, the reinforcing plate 6 is circular, the end surface facing the natural tooth 3 is attached to the upper end surface of the natural tooth 3, and the reinforcing plate 6 is provided with an arc-shaped edge 7 along the circumference. The arrangement of the reinforcing sheet 6 ensures that the two reinforcing rods 5 on the same clamping ring 4 are respectively and further mutually attached to the natural tooth 3, so that the resistance of the clamping ring 4 relative to the rotation of the natural tooth 3 is increased, the possibility of the rotation of the clamping ring 4 relative to the natural tooth 3 is further reduced, and the firmness of the connection between the denture framework and the natural tooth 3 is further improved; the arrangement of the arc-shaped edge 7 enables the tongue of a user to slide over the reinforcing sheet 6 along the arc-shaped edge 7 when the tongue of the user sweeps over the natural teeth 3 provided with the clamping ring 4, so that foreign body sensation brought to the tongue by the reinforcing sheet 6 is reduced, and the comfort of the user is improved.

As shown in figure 3, both sides of the base support 1 are respectively provided with a plurality of arc-shaped limiting blocks 12, one end, far away from the base support 1, of each limiting block 12 is in a spherical shape with smooth periphery, the gums 9 of both sides are respectively abutted and attached to the limiting blocks 12, the limiting blocks 12 are respectively attached to the gums 9 of both sides, the effect of limiting the relative positions between the base support 1 and the gums 9 is achieved, the base support 1 is not prone to being staggered and offset with the gums 9, and the firmness of connection between the base support 1 and the gums 9 is enhanced.

As shown in fig. 1, 2 in-connection of skeleton has bracing piece 8, bracing piece 8 for the arc just laminate each other with the chin, when setting up of bracing piece 8 has consolidated 2 self structural strength of skeleton, still make 2 difficult in-process distortions of chewing rock to the stability of skeleton 2 has been strengthened, has reduced 2 rocks of skeleton and has leaded to appearing the possibility of not hard up condition between artificial tooth support and the natural tooth 3.

As shown in fig. 1, the end surfaces of the framework 2 and the teethridge 9 at the two sides, which are mutually jointed, are respectively provided with air holes 10, and the arrangement of the air holes 10 ensures that wastes generated by metabolism at the teethridge 9 mutually jointed with the framework 2 can be discharged from the air holes 10 in time, so that the biocompatibility is good; the plurality of connecting rods 11 are connected in the air holes 10 along the vertical direction, and the plurality of connecting rods 11 play a role in supporting the air holes 10, so that the air holes 10 are not easy to deform due to downward sinking under stress, and the overall firmness of the framework 2 is improved.

As shown in fig. 1 and 3, the base 1, the framework 2, the snap ring 4, the reinforcing rod 5, the reinforcing plate 6, the support rod 8, the connecting rod 11 and the limiting block 12 are all made of medical pure titanium material with excellent biocompatibility, so that the entire denture framework has good biocompatibility.

The implementation principle of the embodiment is as follows: the base 1 which is tightly propped against the upper end of the teethridge 9 is mutually connected with the teethridge 9 in a mode that a plurality of limiting blocks 12 are mutually propped against the side wall of the teethridge 9, so that the base 1 is difficult to deviate relative to the teethridge 9; a plurality of snap rings 4 support the mode of laminating and natural tooth 3 interconnect tightly each other through anchor strut 5 and reinforcement plate 6 with natural tooth for be difficult to alternate segregation between snap ring 4 and the natural tooth 3, thereby make whole better firm in connection nature that has between artificial tooth support and the natural tooth 3.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
