Description
Technical Field
The utility model relates to the technical field of medical supplies, in particular to a retention clamp for the horizontal direction of massive bones.
Background
At present, dental implantation becomes the preferred repair mode for patients with loss, and sufficient bone mass plays an important role in the long-term prognosis effect of dental implantation surgery. However, clinical defects of soft and hard tissues of jawbone caused by trauma, inflammation, tumor resection, congenital diseases and physiological factors lead to serious deficiency of alveolar bone mass, which brings a challenge to dental implant repair. Therefore, how to effectively increase the alveolar bone mass is a major clinical problem to be solved urgently by the implanting doctors.
Autologous bone grafting is considered the gold standard for vertical bone augmentation. However, autologous bone grafting requires the removal of autologous bone tissue, opening up a second surgical site to be rejected by most patients. Compared with autologous massive bone, freeze-drying treatment of allogeneic bone has obvious advantages: (1) the bone substitute has no immunogenicity, does not cause rejection reaction, but retains the bone induction activity, can induce the formation of new bones and keeps the functions similar to those of autologous bones; (2) selecting proper allogeneic bone block bones according to the size of the bone defect part, and not being limited by a supply area; (3) the allograft massive bone has the same bone regeneration space as the autologous massive bone to maintain the same bone grafting area; (4) since no donor area is needed, there are no complications such as donor area infection when using allogeneic bone; (5) the wound is reduced, and the postoperative reaction of the patient is obviously reduced, such as swelling, pain and the like; (6) simplifies the clinical operation procedure, shortens the treatment time and ensures better experience of patients.
Therefore, at present, the allogeneic massive bone is widely applied clinically, and has obvious curative effect and high acceptance of doctors and patients. However, when the allogeneic bone massive bone is clinically used for bone augmentation, a special tool is not available, so that the clinical operation difficulty is greatly increased, the clinical operation time is prolonged, and the technical sensitivity is improved.
