Embodiment 2

[0042] Embodiment 2, anesthesia: use local infiltration anesthesia. A transverse incision was made near the root of the bony depression on the palatal side of the alveolar ridge, and a trapezoidal incision was made on the mesial side of the labial side of the adjacent teeth on both sides. Use an ultrasonic bone knife or a micro saw to make a mesial-distal incision on the labial side. The incision is slightly wider at the root, 3.0 mm away from the root of the adjacent tooth, from the root to the obvious thickening of the alveolar ridge, and cut through the labial cortex without injuring and palatal cortex. The transverse bone splitting line is located about 3-5mm below the crest of the alveolar crest on the buccal side, and is connected with the mesiodistal bone splitting line.

[0043] Use an osteotomy to chisel gently from the top of the alveolar crest to the root along the direction of the incision, and gradually separate the labial bone plate from the palatal bone plate, ...

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...
