Implantation body-base station connects
Inner Morse taper connects, and promptly taper lock is a kind of known technology in planting tooth, and is widely used in base station and is connected with the safe of tooth implant.Implemented the example of an extensive use in United States Patent (USP) 4,738, the 623 described implantation bodys of Driskell.Also can connect example referring to the Morse taper of other the base station-implantation body described in the United States Patent (USP) 6,290,500 of the United States Patent (USP) 5,888,066 of Morgan and Morgan etc.
Than using screw maintenance widely, inner or outside hexagonal shape tooth implant, known utilization does not have the shortcoming that there is essence in system of implantation body that the threaded interior Morse taper connects.These shortcomings comprise: (1) circular concaveconvex structure makes the location of implantation body's base station of being prepared quite difficult; Can not form straight line when (2) implantation body's base station is bolted in implantation body; When (3) carrying out last repairing under the pressure, circular concaveconvex structure is difficult to prevent that implantation body's base station from rotating; (4) than the plantation analog, implantation body's base station may excessively insert in the implantation body; And (5) implantation body's base station can not insert implantation body and be inserted into the plantation analog until it.The tolerance of using in the preparation method is fewer than the rehabilitation of the base station insertion distance that surpasses plantation analog and implantation body.Following is the example of a proof.Base station is made as follows that with implantation body scheme is connected.The whole height of base station/implantation body's accessory is recorded.Same base station connects with plantation analog (or different implantation bodys on) and carries out same measurement once more.Difference will be above the 100-200 micron.The reason that causes difference will be by means of computer software analysis.The maximum gauge of bulge-structure is 3.0mm; The tapering of two structures is 3 degree.The diameter of this explanation bulge-structure is only less than 6 microns of reference diameter, and this structure will excessively be inserted 100 microns.Along with the increase of tapering, difference diminishes.For example, 11 degree than minor diameter connect the doubly less difference of generation 2-3.But the benefit that taper lock connects will reduce.
The sealed of the whole conical surface between implantation body and the base station finished by a kind of flagellation or cutting thread method.Some patients can find to use flagellation to be placed on base station in the implantation body and be not suitable for.Also can optionally use one to utilize threaded fastener that base station is placed dental implant system in the implantation body.The United States Patent (USP) of Zickmann etc.: 6,726,481 disclose an example that the auxiliary base station of drive screw connects.Therefore, a dental implant system is provided with a base station post, and it has an external taper periphery, the base station that projection of stretching out from base station capital end and total inner surface and outer cylinder surface and base station post projection are complementary.Can be understood as projection has like this increased the total height of implantation body, for implantation body prevent to chew and and tongue more reparation destructive power is provided when moving.It is more difficult that projection also makes angled base station produce.In addition, the above-mentioned base station of the present invention can not destroy base station, moves simply under the situation of crown or jaw tooth or replaces.And, if the hexagonal shape face of base station and implantation body is accurately mated, simultaneously circular cone or Morse's taper connection are ideally operated, this also is very difficult so.For example, the maximum allowance that produces in the course of processing is not less than 12 microns.Produce one 0.5 micron modification in Morse's taper connection.In order to ensure not conflict in Morse's taper connection, must make the hexagonal shape mask of making that is complementary that the mistake that adapts to 12 microns differences that produce on each surface that is complementary than high tolerance is arranged.Even in the worst case, the slit between the interior outer-hexagonal shape can not be less than 24 microns and greater than 48 microns.This will make and when implantation body's index and base station insert a bigger rotation take place between the hexagonal shape.In crown or crossbeam manufacturing process, mistake will be added up.The result produce a maximal phase like and inappropriate reparation.
Implantation body-base station system
The United States Patent (USP) 5,527,183 of O ' Brien discloses exemplary systems in the prior art, comprises that a bottom is provided with external screw thread, and top is provided with the implantation body that a plurality of tapering circumference stretch out member.

Because the space in the artificial tooth is extremely limited, so the size of framework and O shape cycle basis platform is just extremely important.People also attempt to reduce by the curvature that changes the base station pommel whole height of tooth attached accessory.An example is the artificial adnexa of Brevis (http://www.bicon.com/tech/t_odO1.html) of Bicon preparation.The thickness by reducing O shape circle and the diameter of base station bulb can further reduce height and width, and these changes will reduce maintenance power.
The United States Patent (USP) 6,981,871 of MuIIaIy etc. discloses a kind of combination of convex base station, and fixed frame and one are provided with fixing outstanding soft cushioning.It is limited being used for the range of activity that such tooth enclosure group " gives " liner.Described liner must have certain thickness and reach some motion in a big way, and this will increase the width and the height of framework.In addition, than O shape circle, the manufacturing cost of liner also can improve.Another example of O shape circle adnexa is disclosed in the U.S. Patent application of Bulard etc., and publication number is: the US 2002/0177103 of US 2006/0269903 and Pelak and the United States Patent (USP) of Baum 4,681,542.When compound tooth or implantation body were used to support movably artificial tooth, the adnexa of the described type of Baum can carry out work well.On the contrary, if use several teeth or implantation body, semi-rigid connection makes slip only can occur on the vertical direction of adnexa, thereby can give the too much pressure of supporting tooth, and they are damaged.
