Description
Technical Field
The invention relates to the field of dental auxiliary tools, in particular to an alveolar bone defect repairing bone nail.
Background
The tooth implantation operation is a conventional restoration method for dentition loss, and needs to drill an implantation cavity on an alveolar bone and then screw an implant into the implantation cavity so as to combine the implant with the alveolar bone. When the alveolar bone is insufficient in bone quantity, it is difficult to stably couple the implant to the alveolar bone, and thus it is necessary to perform a bone augmentation repair operation on the alveolar bone. Alveolar bone augmentation restoration surgery first fills an autogenous bone or an artificial bone at an alveolar bone defect and then is covered with a dental film to maintain the filled graft bone in a desired shape, and the dental film for covering needs to be fixed with a self-tapping bone screw. However, the existing bone screw has poor stability after being screwed into the alveolar bone.
