Background
In the field of implantology, partial patients have insufficient local residual bone due to disuse or pathological factors, do not meet basic conditions for implantation or cannot obtain good initial stability of the implant, and then bone augmentation surgery is needed to solve the problem of insufficient bone in the area. The guided bone regeneration technique for the purpose of reconstructing bone tissue is named "GBR (guided bone regeneration technique)". The proposal of the guided bone regeneration theory and the maturity of the technology provide a reliable technical guarantee for solving the problem of insufficient bone mass for planting. The definition is that at the bone defect, a biological barrier membrane is utilized to maintain the space established by the operation, and thereby epithelial cells and fibroblasts which proliferate fast are prevented from growing in, and the growth of osteoblasts and blood vessels which proliferate at slow speed is ensured. The titanium nail and the titanium mesh play unique advantages in the application of guiding bone regeneration, and the good mechanical property of the titanium nail and the titanium mesh can provide supporting protection for bone regeneration and reduce the bone supply quantity required by autologous bone transplantation.
The traditional titanium mesh bone grafting is preformed according to the shape and size of bone defect in an operative area, and the titanium mesh is fixed on a non-defective jawbone adjacent to the bone defect by using titanium nails in the operation so as to provide a bone forming space for bone regeneration. However, the conventional titanium mesh bone grafting instrument for fixing the titanium nail is usually a manual instrument, and the labial retention is still feasible, but when the palatal side or lingual side uses the titanium nail for fixing the titanium mesh, the manual instrument is too long, the angle of the manual instrument is inconvenient to hold, and the problems of blind area, unclear vision and difficult retention on the lingual side exist; the blood vessels on the lingual side are more, the operation difficulty is higher, the range of flap-turning operation in the operation is larger, and the postoperative swelling condition of a patient is more serious; when the bone defect area is close to the adjacent tooth, the titanium mesh fixing operation may have the risk of damaging the tooth root of the adjacent tooth; leading to lingual retention titanium mesh as a clinical problem.
Therefore, improvement is urgently needed to overcome the defects in the prior art.
