Abstract
The utility model discloses a single -piece tooth planting body, including planting body base station and planting body root, plant body base station and plant body root axial seamless connection, to plant body root and be equipped with the external screw thread, external screw thread tooth side surface at least on one side is the mat surface. The utility model discloses planting body root and bone tissue realization " synostosis " on every side be favorable to, the spin phenomenon can be obstruct simultaneously.
Description
Technical field
This utility model relates to medical domain, particularly relates to a kind of tooth implant.
Background technology
The tooth implant of single-piece or integral type or one-part form refers to that the morphosis that these two functions of implant base station/foundation pile and implant root are different is the biological implantable component that seamless link becomes as a whole.Object is in order to avoid top foundation pile/base station and the problem that loose shift may occur because of being connected or coming off between tooth implant root; Also not closely sealed, Micro blazed-grating problem that between dividing because of two component portions be separated, connected mode produces can be avoided may to cause problem that is scorching around implant, secondary infection.The smooth surface of existing single-piece tooth implant, bad with " synostosis " of surrounding bone tissue, easily there is spin phenomenon simultaneously.
Utility model content
This utility model aims to provide a kind of single-piece tooth implant, and implant root surface, through roughening treatment, is conducive to implantation body's root and surrounding bone tissue realizes " synostosis ", while can hinder spin phenomenon.
For achieving the above object, this utility model realizes by the following technical solutions:
Single-piece tooth implant disclosed in this utility model,
Comprise implant base station and implant root, described implant base station and the axial seamless link of implant root, described implant root is provided with external screw thread, and described external screw thread at least tooth side surface is matsurface.
Further, be matsurface at the bottom of described external screw thread tooth.
Preferably, described matsurface is knurling and/or fish scale-shaped and/or wavy.
Further, the bottom of described implant root is frustroconical, and small end is away from base station.
Preferably, comprise pit when described matsurface is fish scale-shaped, described pit is hemispherical or dish-shaped, and described pit is in string arrangement, and when pit is dish, radius is 0.2mm.
Preferably, described externally threaded tooth side half-angle is 25
0, another side is 15
0.
Preferably, the radial dimension of described implant base station is greater than the radial dimension of implant root.
Preferably, described implant base station bottom is reverse frustoconic, and small end connects implant root.
Further, described base station upper end is outward-dipping, and gradient is 0-35 degree.
Further, described matsurface is the matsurface after acid etching.
The beneficial effects of the utility model are as follows:
1, implant root surface is through roughening treatment, add the degree of roughness of screw thread facing, effectively add the surface area that facing is combined with osseous tissue, the coefficient of friction in recruitment implant surfaces and osseous tissue face, add the initial maintenance state of implant, be more conducive to implantation body's root and surrounding bone tissue realizes " synostosis ".
2, implant root has been designed to certain taper, has been with externally threaded taper shape, and tapering is conducive to advancing wedging, and screw thread is conducive to connection between implantation body with bone, chimeric and stablize; Implant root is tapered, and thread surface and Luo Dao have two kinds of forms, can the squeezed expansion recipient bed of appropriateness when rotating into bone hole, enables implantation body obtain good initial maintenance effect, especially for three, the four class bone better effects if that sclerotin is comparatively loose.
3, because the reverse taper of single-piece adjustable grinding core shape thread implant foundation pile frustro conical sloping platform increases top base station Zhou Jing, it is made to have larger ground leeway.After tooth implant is implanted, can by doctor on demand in oral cavity direct reconditioning adjust and reform top foundation pile, again formed a kind of wear into temporarily or permanent dental crown to root side's polymeric species structure, change the axial angle of foundation pile simultaneously, obtain the aesthetic property of reparation.
4, the tooth side machining recessed degree in hole that formed is obviously (for conventional machine processing technique can not be processed to form), roughness obviously, if after adding acid etching, more be conducive to bone cell growth, after forming synostosis, anti-spin effect strengthens, and effect is better.From mechanism and the effect of material and osseointegration, be better than ganoid tooth side.
5, the implant base station solving tooth implant root and assembling corona may present the problem of gyration in upper lower jaw occluding relation, user 1. can by the mode of direct reconditioning/cutting, change the mode of appearance of foundation pile, change the line relationship of foundation pile and root, make it can cut the arbitrarily angled foundation pile being formed and be not more than 60 degree; 2. can the implant base station of preform certain angle form directly use.
6, the single integrated member that formed continuously of implantation body top base station and root, completely avoid both because of the foundation pile that may occur after relying on central screw or binding agent to fix during released state rotates or loosens displacement.
7, avoid the adjustment base station angle of bending by force and occur the complication that implant neck fractures;
8, the base station maintenance form of reconditioning molding on demand can obtain larger surface area, is conducive to the making of corona;
9, be good to eat interior reconditioning base station form after plantation, be convenient to dentures repai temporarily or permanently, shorten treatment time.
