Abstract
The utility model discloses a modular horizontal tooth planting body of soft tissue, including the base station of tooth planting body, plant body root and connect the base station, plant the set screw of body root, 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 more be favorable to tooth planting body root and bone tissue realization " synostosis " on every side, can obstruct simultaneously and plant the spin phenomenon of the body under the exogenic action.
Description
Technical field
This utility model relates to medical domain, particularly relates to a kind of tooth implant.
Background technology
In order to avoid the implantation body implanted is subject to chewing the interference of gmatjpdumamics or the direct effect of excessive gmatjpdumamics in early days, is root and base station two large divisions by tooth implant segment design, is connected into as a whole structure with central screw therebetween.The morphosis of simulation natural tooth root, is designed to conical or cylindrical two kinds of forms.
Combined cylindrical shape screw thread Gen Xing implantation body, be placed in osseous tissue by planting or implantation body's root that soft tissue hides divides and is emerging in oral cavity or Abutment part on soft tissue coverage rate forms two individual members of released state, by central authorities fix/trip bolt connects combining form and becomes a new integral component use.According to morphosis and function two components are divided into root (containing through soft tissue or gingiva tissue smooth neck) and top base station (implant cervical region moving on to the narrowed portion of base station close to root) two parts, wherein root is a component, and top base station (containing implant neck) is another component.
Implant to make implantation body after namely recipient bed enters bone hole and can obtain a good initial maintenance state, namely between the Gen Xing implantation body of thread surface and osseous tissue in a kind of " mechanicalness chimerism ", be conducive to the later stage implantation body and osseous tissue between can realize gradually " synostosis ", designed implantation body's root main body is cylindrical, surface have the screw thread (tooth) that rotates apart from equal clockwise direction and screw thread ditch around, operator uses suitable twisting resistance (being generally advisable in 35-75 newton) to be fastened on implantation body by implant bed to screw in mode.
The angle that tooth implant bears jaw power size and implantation body's root body surface area and synestotic effective area proportional is considered, designed cylindrical implant root body surface is processed into screw thread and the Luo Gou of certain altitude or the degree of depth, diameter and length equal-specification varied, effectively can utilize the length, width and the thickness that lose tooth region residual alveolar ridge or bone, realize the object of maximum using bone.
Existing combination type tooth implant, most smooth surface (machining formation), bad with " synostosis " of surrounding bone tissue (initial stage of especially implanting), and coefficient of friction between contactant or material is less, easily occurs spin phenomenon simultaneously.
Utility model content
This utility model aims to provide the horizontal tooth implant of a kind of combination type soft tissue, and implant root ridge side surface is matsurface, is conducive to implantation body's root and surrounding bone tissue realizes " synostosis ", can hinder spin phenomenon simultaneously.
For achieving the above object, this utility model realizes by the following technical solutions:
The horizontal tooth implant of combination type soft tissue disclosed in this utility model, comprise the base station of tooth implant, implant root and be connected the hold-down screw of base station, 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 °, and another side is 15 °.
Further, described implant root crest comprises interior hexagon seat, and described base station bottom is reverse frustoconic, small end under, base station bottom surface central authorities is provided with the downward hexagon boss with interior hexagon seat adaptation.
Further, described interior hexagon seat bottom surface is provided with axial blind hole, and described base station is provided with the through hole coaxial with axial blind hole, and described hold-down screw is all threaded with axial blind hole, through hole.
Preferably, described base station upper end is outward-dipping, and gradient is 0-35 degree.
Further, described matsurface is the matsurface through 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.
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, hexagon seat in implant root end face/sink to the bottom the interface forming root and base station or other top connectors with inverted cone ground, the object reducing operation number of times can be reached, ensure that mucous epithelium and the soft tissue of implant neck can form the closed object of good cuff, implantation body's root and neck portion design are processed into the component of one, implement once to perform the operation, implant neck plane is placed in 1-1.5mm under mucomembranous surface.
