The relationship of mandibular length to residual ridge loss was studied in 22 edentulous patients. Tracings made from cephalometric films taken at initial insertion of complete dentures and at 20 years after placement were measured. Mandibular length was determined to have no statistical relationship to the reduction in residual ridge height in either the maxillae or the mandible. In addition, alveolar bone loss in the one jaw had no relationship to the amount of loss in the other jaw.
对22例无牙颌患者下颌长度与剩余牙槽嵴吸收的关系进行了研究。测量了全口义齿初戴时及戴入20年后拍摄的头影测量片上的描迹。结果表明，下颌长度与上颌或下颌剩余牙槽嵴高度的降低均无统计学关系。此外，一侧颌骨的牙槽骨吸收与另一侧颌骨的吸收量也无关。
