摘要
目的随机选择52例单侧完全性唇腭裂患者,其中男性31人,女性21人,牙槽突植骨手术进行时,病人的年龄范围9至26岁,平均年龄15.2岁。方法在牙槽突植骨手术后对病人定期随访并拍摄上颌前部咬合片和上颌体腔片。分析上述两种X线片在评价牙槽裂隙部位牙槽骨高度的作用时,使用同一天拍摄的上颌体腔片和上颌前部咬合片。拍摄所分析的X线片时,裂隙侧尖牙已经萌出。评价标准采用1986年Bergland等所提出的临床分级方法进行。每种X线片分别进行两次评价,两次评价间间隔一周。结果上颌前部咬合片和上颌体腔片在评价牙槽突植骨部位的牙槽骨高度上没有本质的区别。结论正畸治疗前判断牙槽突高度时,既可以选择上颌体腔片也可以选择上颌前部咬合片。
Objective To investigate the reliability of anterior occlusal radiograph and intraoral panograph in the assessment of the outcome of the secondary alveolar bone grafting in patients with cleft lip and palate. Methods Fifty-two patients （31 males and 21 females） with complete unilateral cleft lip and palate （UCLP） were randomly selected. The age range was 9 to 26 years when the secondary alveolar bone grafting was carried out. After the surgery, the patients were followed up and taken the anterior occlusal radiograph and intraoral panograph regularly, Anterior occlusal radiograph and intraoral panograph taken at the same day were used in the assessment, The cleft canine had fully erupted when the radiographs were taken. Bergland criteria were used to assess the outcome of the secondary alveolar bone grafting using different radiographs on two separate occasions one week apart. Results The agreement of the anterior occlusal radiograph and intraoral panograph in the assessment of the secondary alveolar bone grafting was perfect. Conclusions Both radiographs could be used to assess the interdental septal height before orthodontic treatment.
