Technical Field

The invention relates to the technical field of dental implants, in particular to an osteogenesis tool for eliminating bone disorders around a dental implant and a method for eliminating the bone disorders.

Background

The dental implant is a tooth missing restoration method for supporting and retaining upper dental restoration based on the lower structure implanted in bone tissue, and includes two parts of lower supporting implant and upper dental restoration. The implant with the shape similar to a tooth root is usually made of materials such as metal, ceramic and the like, is implanted into tissues (usually upper and lower jaws) through an operation method and is fixedly retained and supported by bone tissues, and is connected with a dental prosthesis supporting the upper part through a special device and a special mode.

However, through clinical verification and with the deepening of clinical application and research, the following defects are found in the dental implantation process: the alveolar bone is not absorbed completely after tooth extraction, a sharp bone margin or a ridge is left, at the moment, implant repair is carried out, alveolar bone trimming operation needs to be carried out firstly to enable the alveolar bone trimming operation to be flat and natural, but the step process of the alveolar bone trimming operation is complex, a patient needs to go through flap turning, bone removing, bone face filing, bone fragment flushing and removing, and after mucosa restoration, the wound is intermittently or continuously sutured for 7 days, and the suture is removed, so that great damage and pain are caused to the patient, and financial and time losses are caused.

Disclosure of Invention

In view of the above situation, the present invention provides a bone formation tool for eliminating bone disorders around a dental implant and a method for eliminating bone disorders, which solves the problem that the prior art cannot solve that after the implant is implanted into an alveolar bone, a bone drill can not be used continuously and the gingival height can not be measured accurately by probing with an oral probe.

The technical proposal is that the bone forming tool which can eliminate the bone obstacle around the dental implant is a single body and is arranged at the upper end of the implant connected with the dental prosthesis, the bone shaping tool comprises an upper end part matched with the bone taking drill and a lower end part connected with the implant, the upper end part and the lower end part are both cylindrical structures, the diameter of the upper end part is larger than that of the lower end part, a transition section which is integrally conical is arranged between the upper end part and the lower end part, the diameter of the upper end part is larger than that of the lower end part, the surface of the upper end part is provided with a plurality of scoring grooves which are arranged at equal intervals in the vertical direction, the surface of the lower end part is provided with threads, the upper end surface of the implant is provided with an inner groove which is matched with the threads and is provided with threads, the implant and the inner groove are connected through the threads, and the wrench groove structure on the upper end surface of the upper end part is convenient for a wrench to operate a bone forming tool.

Furthermore, the edge of the upper end face of the upper end part is a smooth fillet, so that perfect fit with the bone drill can be realized, and a limiting effect can be realized.
