Problems solved by technology

However, the current common technique of implantation after distraction osteogenesis requires implanting a bone distractor into the jawbone, increasing the bone mass of the implant bed through distraction osteogenesis, and then removing the bone distractor (usually about 3 months) before placing the implant. Implantation, so it has a series of disadvantages such as many operations, long treatment course, increased surgical trauma and treatment costs; and the current clinically used bone distractor has a large shape, and there are still discomfort when wearing it in the mouth, and susceptibility to infection, etc. insufficient
The above-mentioned shortcomings of the existing bone distractor limit the application of distraction osteogenesis technology in the implant field to a certain extent

Embodiment Construction

[0014] Based on the principle of bone distraction and implant osseointegration, the present invention researches and designs a bone distraction implant, and combines the bone distractor and the implant together so that it has the dual functions of the bone distractor and the implant. Function, during bone distraction, the implant can be used as a fixed anchorage for distraction osteogenesis, which not only increases the retention force, but also enables the osseointegration of the implant to be completed at the same time as the distraction osteogenesis; after the bone distraction ends , as an implant supporting the upper structure of the denture, it can continue to stay in the bone to perform its function, avoiding secondary surgery.

[0015] The invention is an implant with distraction osteogenesis function. The shape of the main body of the implant is a cylindrical threaded sleeve structure with a common central axis. Such as figure 1 As shown, the implant consists of a bu...

Abstract

The invention discloses a bone stretching type implant. The appearance of the implant main body is a sleeve screw thread columnar structure with a common central shaft, and the implant main body consists of an internal central screw, an external hollow annular screw thread column and an assistor. The implant has light and comfortable structure as well as simple operation, does not need repeated surgeries and saves the treatment time. The invention provides a convenient, reasonable and effective therapeutic concept and method for the implantation restoration treatment to a patient with shortage of bone quantity.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an implant with distraction osteogenesis function. Background technique [0002] The technology of implanting artificial tooth roots into alveolar bone to achieve osseointegration (generally about 3-6 months) to support artificial dentures is called dental implant technology, and artificial tooth roots are implants. It has the characteristics of less damage and good long-term curative effect, and is the first choice for people to restore missing teeth. However, for some patients with alveolar ridge resorption, the lack of bone in the implant bed will bring certain difficulties to direct implantation. Distraction osteogenesis (DO) is the installation of some kind of distraction device, so that the bone tissue at the osteotomy is subjected to slow and steady traction and tension at a certain speed and frequency, activating the proliferation and synthesis of cells, and prom...
