摘要
目的：为下颌后牙区牙槽嵴增高术提供定量指标。方法：对 109 具成人离体下颌骨后牙区不同部位高度进行了测量。结果：颏孔上缘至牙槽嵴顶高度，有牙侧（13.95±2.45）mm，无牙侧（8.77±2.75）mm，平均值相差 5.18 mm；颏孔区下颌体高度，有牙侧（31.65±3.09）mm，无牙侧（24.67±3.88）mm，平均值相差 6.98 mm；下颌后牙区下颌体高度，有牙侧（29.15±2.91）mm，无牙侧（23.03±4.11）mm，平均值相差 6.12 mm。结论：选择颏孔和颏孔后 1.0 cm 分别作为双尖牙区、磨牙区下颌骨高度测量的标志点，方法简单，位置较恒定。下颌后牙区颌骨垂直吸收 5-7 mm，可供该区牙槽嵴增高术参考。
Objective:To provide a quantity index for alveolar ridge augmentation at mandibular posterior area.Methods:According to anthropometry,the height of different points of mandibular posterior area was measured on 109 adult mandibles.Results:The height between superior margin of mental forman and alveolar ridge crest,dentulous side （13.95±2.45）mm,edentulous side （8.77±2.75）mm,difference of mean value 5.18mm;mandibular body heigt at mental forman area,dentulous side （31.65±3.09）mm,edentulous side （24.67±3.88）mm,difference of mean value 6.98mm;mandibular body height at posterior area,dentulous side （29.15±2.91）mm,edentulous side （23.03±4.11）mm,difference of mean value 6.12mm.Conclusion:To measure mandibular height at premolar and molar area,the use of mental forman and the point 1.0cm behind mental forman as mark point presents advantages such as approaching simply,constant measuring location and high reliability.The mean loss of bone at mandibular posterior area is 5－7mm,which should be referrible for alveolar ridge augmentation.
