The length N of this utility model implantation body head cylindrical section 10 has two fixed values, i.e. fundamental length (N
1) and fundamental length add 1.2 millimeters (N
2), fundamental length derives from the shape analysis to natural tooth root, is the numerical value after the technical finesse of a process, and N
2Then be to have analyzed than the right root shape of the vast of heaven, draw after the longer implantation body constitutional balance factor, these two length fixed values are applied to the group of two implantation body's total length L respectively, promptly short type group and elongated group, the length T of ball shape tail end 12 also is fixed, and total length L has several fixed values, forms one kind and plants body length series, therefore, total length L just has:
Short type group total length (one group of setting)=N
1(being fundamental length)+T+C,
Elongated group total length (one group of setting)=N
2(be fundamental length N
1+ 1.2mm)+T+C,
Therefore, the length C of conical section 11 is determined by total length L, changes.
The statistic analysis result of used implantation body length in China's tooth-planting practice has also been considered in the length definition, and such distribution of lengths is convenient to plant the doctor and is made one's options, and the ratio between cylindrical section length and total length has also embodied natural tooth root contour structures characteristics.
This utility model implantation body cylindrical section 10 is provided with little screw thread 18 near surface, head place, the thread form of this little screw thread is symmetric 90 degree trianglees, can increase and the bone contact area of cortical bone particularly, therefore can improve primary stability and secular synosteosis stability.
This utility model has on implantation body's cylindrical section 10 on the surface of remaining surface the surface of little screw thread and conical section 11, also be provided with external screw thread 19, external screw thread begins gradually to be entered in the body certain depth deeply and kept this degree of depth by the surface from screw head on cylindrical section, and on conical section towards the gradually shallow distribution of afterbody, and withdraw from the junction of conical section and ball shape tail end, the form of thread is asymmetric trapezoidal in addition, near implantation body's head one side is 8-12 degree hypotenuse, and makes 28-32 degree hypotenuse near afterbody one side.
This utility model implantation body inside is provided with cavity, cavity is made up of conical bore 14, short cylindrical hole 15, long cylinder hole 16 and screwed hole 21 etc., wherein the hole wall in long cylinder hole 16 is provided with 2-6 square key 17, implantation body outer surface centre position also is provided with 1-4 bar cutting slot 20, flute profile is an angle of 90 degrees shape, is used in implant surgery implantation body's self tapping being screwed in the bone.
This utility model base station 2 is provided with taper seat 27, the face of cylinder 29 of matching with implantation body 1, and the face of cylinder 29 be provided with the implantation body cavity in the rectangle keyway 28 of quantity such as square key 17, square key and rectangle keyway are fitted to each other, and can realize the circumferential location and the anti-spinfunction of base station.
The beneficial effects of the utility model are: 1, planting body is imitative natural tooth root form, and the similar natural tooth root of stressing conditions can reduce the shear stress on the bone planting body faying face. 2, the little screw thread on the planting body head face of cylinder can increase the contact area with bone, increases primary stability and favourable synosteosis long-term effect. 3, implant surface has external screw thread, embed the contact area that can greatly increase in the bone with bone after implanting, obtain good primary stability, simultaneously, external screw thread also can be reallocated to stressed, be distributed to it on bigger helicoid and pass to bone, this can change stress direction and reduce the stress absolute value. 4, planting body is connected with taper seat between base station, and good sealing property can be provided, and consists of the conversion of Abutment connecting platform, i.e. platform transformational structure can reduce or eliminate the bone absorbing phenomenon after the plantation.
