Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly to a kind of implantation body central screw fracture residue drill through time spacing regulator.
Background technology
After tooth implant implants human body alveolar process or jawbone, through the Integrated implant effect of certain time, ossify with the cortex of osseous tissue and make implant be difficult to the entirety separated, i.e. synosteosis state with bone formation in implantation body's root surface.
And combination type dental implant system is mainly made up of following three part-structures: 1. implantation body's root, i.e. heeling-in becomes the foundation part of Dental Implant in alveolar process or jaw bones tissue；2. implantation body top base station, i.e. connects and fixes the corona of multi-form or the effect of other dummies；3. central authorities of implantation body connecting rod (i.e. implantation body's center screw nail), bar portion passes base station hollow region, and screw thread is by implantation body's top base station bolt/fixing/be tightly locked in implantation body's root so that it is becomes and can not loosen/inseparable entirety.
During Clinical practice, there are two kinds of situations that the central screw of fixed race phytyl platform may be caused to rupture: 1, in the operating process installing implantation body's top base station, cause the fixing screw of central authorities to fracture owing to moment is excessive during reinforcing；2, the synostosis time is formed between combination type Gen Xing implantation body and bone longer, the supporting base station in its top and corona are connected in one after relying on central screw that diameter is thinner fixing formula implant denture, when it exercises masticatory function, after shearing jaw power effect by long-term repeatedly iterative cycles, central screw metal produces fatigue, and central screw body may be caused to rupture.
The most no matter which kind of reason causes Dental Implant base station to fracture with the interface unit of implantation body root, i.e. central authorities' retention pin body fractures, its Remained mass it is difficult with simple despining method in the rivet nut portion taking root in body central authorities and takes out, fracture especially with the screw after the binding agent of enhancing Screw retained effect, can not simply take out or change especially.Now implantation body is good with the bonding state of osseous tissue, or it is fully achieved synostosis state, taking out central screw Remained mass, the screw more renewed can make it regenerate use, then can carry out a mouthful transluminal operation clinically and drill through Remained mass root medium pore tapping again of taking root kind.
Under normal circumstances, the material hardness of combination type implantation body central screw is high (billon, titanium alloy etc.) compared with the hardness of implantation body's material, external existing taking-up mode or way use employing high speed drill and directly bore and remove, but hand-held set head tremor throw is big, poor stability, it is easily caused drill bit displacement when directly drilling through and deviates the axis position/center of implantation body, cause drilling through failure.
