Improvement of bone splitting carried out below lip-cheek crest in oral implantation

Abstract

The invention provides an improvement of bone splitting carried out below a lip-cheek crest in oral implantation. The improvement is characterized in that a splitting inlet is located in the lip-cheek crest, and the starting point of a bone splitting line is designed at the near-root end of a concave area of a lip-cheek side bone. The bone splitting method includes the following steps: a horizontal bone splitting cut line is formed at the near-root end of the concave area of the bone through an ultrasonic bone knife, two longitudinal splitting lines are additionally and respectively formed in a near cut, a distant cut and a middle cut, the bone splitting is carried out through the horizontal cut line, and meanwhile an implant, bone implantation powder and a bone cover membrane are implanted. Usually, a Biogide bone membrane is used for covering when Bio-oss bone powder is implanted. The situation that a bone plate is broken in the bone concave area in the splitting process is avoided, the implantation direction of the implant can be in an ideal position, the condition that the implant is supported by sufficient bones around the implant is guaranteed, and retaining of bone cortex of the crest facilitates stability in the early stage.

Description

technical field [0001] The invention relates to a dental implant implantation method, in particular to a bone splitting technique under the buccal crest top in oral cavity implantation. Background technique [0002] The traditional superposition method of bone transplantation in implant surgery has many disadvantages, such as the need to open up a second surgical area, poor shaping, high risk of infection, difficulty in implanting implants at the same time, long operation period, and bone absorption. In this area, if the height of the ridge is reduced, the aesthetic effect after implant restoration will be greatly affected. A single GBR [GBR (guided bone regeneration) guided bone regeneration technology refers to the use of barrier membrane properties to prevent fibroblasts from the surrounding soft tissue, allowing osteoblasts on the bone surface to have enough time to proliferate, and finally achieve tissue regeneration and orientation. purpose of repair. ] It is difficu...

Problems solved by technology

[0004] like figure 1 , 2 As shown, the starting point 1 of the bone splitting line in the existing bone splitting operation is located at the top of the alveolar, and the splitting line 2 is obliquely from the top of the alveolar to the apex, and the incision is parallel or slightly wider at the root. When the defect is obviously depressed, the labial bone flap is easy to break when the bone splitting is used
