研究目的:

使用锥形束计算机断层扫描(CBCT)和Mimics软件,回顾性比较牙槽嵴保存术中自体牙骨粉与牛骨骨粉的治疗效果差异,为临床上医生术前选择不同类型的植骨材料提供指导依据。  

Objectives of Study:

Using cone-beam computed tomography (CBCT) and Mimics software, to retrospectively compare the therapeutic effects of autologous tooth bone powder and bovine bone powder in alveolar ridge preservation, and to provide guidance for clinical doctors to choose different types of bone graft materials before surgery.
