Problems solved by technology

[0002] In clinical dental implantology, there is often a special edentulous patient. For example, the bone density of the alveolar bone in the edentulous area is low, and bone compression surgery is required to complete the conventional intraosseous implant surgery. Osteonecrosis, which is not conducive to implant osseointegration

Embodiment

[0049] Such as Figures 1 to 7As shown, the present invention adopts pure titanium material to machine the implant body, and the exterior is cylindrical or conical, with diameters of 4.0mm, 4.5mm, 5.0mm, and 5.5mm in four specifications, and lengths of 8.0mm, 9.0mm, and 10.0mm. mm, 11.0mm, 12.0mm five specifications.

[0050] Such as image 3 and Figure 4 As shown, the anti-rotation wing is located inside the implant before the implant is in place, and after the implant is in place, use Figure 7 The wrench rotates the internal mechanism, and the anti-rotation wing is screwed out and locked.

[0051] The upper end of the implant body core 8 is provided with a lower concave cavity 11, the lower concave cavity 11 includes a threaded section for cooperating with the abutment screw 7 and a wrench operating section for cooperating with the operating wrench to realize rotation, the threaded section is set At the upper end of the wrench operating section, the wrench operating se...

Abstract

The invention discloses an anti-rotation and anti-dislocation oral implant system. The system comprises a base, an implant and a base screw, and the base is arranged on the implant and fixed through the base screw; the implant comprises an implant inner cavity and an implant inner core arranged in the implant inner cavity, anti-rotor mechanisms are arranged on the implant inner core, and rotor outlets which are used for the anti-rotor mechanisms to extend out of and used for locking the implant are formed in the implant. The anti-rotation and anti-dislocation oral implant system for preventingthe base screw from being broken is mainly applied to patients with insufficient bone mineral density of the alveolar bone of the agomphosis area, by increasing the implant-bone contact area, the primary stability of the implant is improved, and implant dislocation is prevented; through the antagonistic effect of the anti-rotor mechanisms, the implant is prevented from rotating; by providing a fulcrum for the lower portion of the base screw, the base screw is prevented from being broken when subjected to lateral force.

Description

technical field [0001] The invention relates to the technical field of implant restoration after tooth loss. Specifically relates to an anti-rotation and anti-dislocation oral implant system. Background technique [0002] In clinical dental implantology, there is often a special edentulous patient. For example, the bone density of the alveolar bone in the edentulous area is low, and bone compression surgery is required to complete the conventional intraosseous implant surgery. Osteonecrosis is not conducive to implant osseointegration. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide an anti-rotation and anti-dislocation oral implant system, so that patients with low alveolar bone density in the edentulous area can avoid problems such as implant rotation and dislocation after implant surgery . [0004] To achieve the above object, the present invention adopts the following technical means: [0005] An an...
