Abstract

The invention discloses an alveolar bone defect repair bone nail, and the bone nail comprises a rod part; a thread is arranged on the outer wall of the rod part, the thread is provided with an alveolar cavity, the alveolar cavity comprises a bearing tooth side, a guide tooth side, a first arc surface and a second arc surface, and the bearing tooth side, the second arc surface, the first arc surface and the guide tooth side are sequentially arranged from front to back; the rear side of the first cambered surface and the leading flank are in smooth transition; the rear side of the second cambered surface and the front side of the first cambered surface are in smooth transition, the front side of the second cambered surface and the bearing tooth side are in smooth transition, and the arc radius of the second cambered surface is smaller than that of the first cambered surface. According to the alveolar bone defect repair bone nail, the alveolar bone is more attached to the first arc surface and the second arc surface, so that the stability of the bone nail is improved after the bone nail is screwed into the alveolar bone; and the alveolar cavity forms a barb structure, so that the alveolar cavity of the thread and the alveolar bone form an occlusion structure, and the stability of the bone nail screwed into the alveolar bone is improved. The invention can be applied to dental auxiliary appliances.

Description

technical field [0001] The invention relates to the field of dental auxiliary appliances, in particular to bone nails for repairing alveolar bone defects. Background technique [0002] Dental implant surgery is a conventional repair method for missing dentition. Dental implant surgery requires drilling an implant cavity on the alveolar bone, and then screwing the implant into the implant cavity to combine the implant with the alveolar bone. When the amount of alveolar bone is insufficient, it is difficult for the implant to be firmly combined with the alveolar bone, so it is necessary to perform bone augmentation surgery on the alveolar bone. Alveolar bone augmentation repair surgery first fills the alveolar bone defect with autologous bone or artificial bone, and then covers it with dental membrane to keep the filled graft bone in the desired shape, while the dental membrane used for covering needs to use self-tapping Pin fixation. However, the stability of the existing b...
