【摘要】：目的:应用锥形束CT研究错鉭畸形切牙区唇侧牙槽骨开窗及开裂的发生率等分布情况。方法:选择2010年7月~2015年9月期间在汉中市口腔医院正畸科进行锥形束CT扫描的患者421例,统计在上下颌切牙区唇侧牙槽骨开窗及开裂的发生率和分布情况,并进行统计学分析。结果:在统计的421例患者中,骨开窗及骨开裂的发生率分别为38.95%和20.43%。骨开窗以骨性Ⅰ类错鉭最多39.49%,骨性Ⅱ类次之。骨开裂以骨性Ⅱ类错鉭33.82%最多,骨性Ⅰ类次之。骨开窗牙位以左上侧切牙最高20.43%,骨开裂牙位以左下侧切牙最高6.65%。结论:正畸治疗患者中,骨开窗及骨开裂的发生率分别为38.95%和20.43%,无性别差异,骨性Ⅰ类错鉭切牙区骨开窗的发生率最高,以上侧切牙为主,骨性Ⅱ类错鉭切牙区骨开裂的发生率最高,以下中切牙为主。
[Abstract]:Objective: to study the incidence of fenestration and cracking of labial alveolar bone in malformed tantalum incisor by conical beam CT. Methods: from July 2010 to September 2015, 421 patients underwent conical beam CT scanning in orthodontics department of Hanzhong Stomatology Hospital. The incidence and distribution of alveolar bone fenestration and dehiscence in upper and lower incisors were analyzed. Statistical analysis was carried out. Results: the incidence of bone fenestration and bone fracture were 38.95% and 20.43% respectively. Bone type I misplaced tantalum was the most common bone fenestration, and bone type 鈪，
