Problems solved by technology

After a period of time, the bone tissue around the implant neck gradually shrinks due to lack of exercise, resulting in loosening of the implant, which in turn causes implant failure

Embodiment Construction

[0028] The specific embodiment of the invention will be further described below in conjunction with accompanying drawing:

[0029] Such as figure 1 As shown, a wedge-type expansion type dental implant device with an expansion block includes a threaded abutment 1, an implant body 2, an adjusting screw 3 and an expansion block 4, and the length of the dental implant device is 12-14mm, the implantation depth is 8-10mm.

[0030] Such as figure 2 As shown, the length of the threaded abutment 1 is 10-12mm, and the inside of the threaded abutment 1 is provided with a hexagonal groove, which is convenient for tool installation and disassembly through the groove. The bottom end of the threaded abutment 1 is provided with an abutment external thread 12 .

[0031] Such as image 3 and Figure 4 As shown, the shape of the implant 2 is cylindrical or conical, and patterns such as knurling are arranged on its outer surface. The interior of the implant 2 is provided with an expansion ...

Abstract

The invention relates to an inclined wedge-type expansion-type dental implantation device with an expansion block. The device comprises a base station with threads, an implant, an adjusting screw rodand an expansion block, wherein the interior of the implant is provided with an expansion conical hole penetrating the lower end of the implant, and the interior of the implant is also provided with ascrew rod mounting hole communicated with the expansion conical hole; an expansion cut groove and a micro cut groove are distributed from the lower end to the neck of the implant; the adjusting screwis connected to a threaded base and inserted into the screw rod mounting hole of the implant, and the expansion block is embedded into the expansion conical hole of the implant through the adjustingscrew of the adjusting screw rod. The device is simple in structure and good in implantation effect. The expansion block and the adjusting screw are mutually matched, and the expansion block move upwards along the central axis of the implant so as to achieve the effect of expanding the implant; and the contact area between the implant and the bone is improved through the micro cut groove, so thatthe secondary stability is improved, the implantation failure rate can be effectively reduced, the implantation efficiency is improved, on the other hand, the friction force between the implant and the bone can be improved, and the implant is prevented from loosening in the initial stage of implantation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a wedge-type expansion-tightening dental implant device with an expansion block. Background technique [0002] Dental implant technology has become more and more mature since the 1990s. Implant restoration is a common dental restoration technology. Usually, dental implants are also called "artificial tooth roots", and titanium or titanium alloys are used for better biocompatibility. Made of high-quality materials, it is implanted in the patient's edentulous jawbone to replace the natural tooth root and firmly support the upper crown. Dental implants are beautiful, natural and realistic in appearance, and the cleaning of implants is also fundamentally different from traditional dentures. Traditional dentures need to be removed for cleaning, while implants are cleaned in the same way as real teeth. In addition, the traditional porcelain restoration technology may need to m...
