摘要
目的：探讨中国人上颌骨后牙区牙槽骨高度的增龄性变化。方法：选取双侧副鼻窦螺旋cT检查结果正常的患者资料540例，其中男、女各270例，年龄9—81岁，按年龄分为9组（n=60，其中男、女各30例）：A组7—12岁，B组13—17岁，C组18～20岁，D组21—24岁，E组25—28岁，F组29—35岁，G组36～40岁，H组41～65岁，I组66～81岁。测量各组牙槽骨高度，统计增龄变化的差异。结果：男、女间牙槽骨高度在同一年龄组无统计学差异（P〈0．05）。牙槽骨高度A组高于B组，B组至E组逐渐增高，E组达到高峰，F组明显下降，G组又明显增长，G组至I组保持在同一水平。结论：中国人牙槽骨随年龄变化而改变，40岁后达到稳定状态。
AIM： To investigate the age - related changes of posterior alveolar bone height of maxilla. METHODS： 540 individuals with normal paranasal sinus spiral CT examination results were enrolled in this study. The subjects were divided into 9 groups according to age（years） （ A ：7 - 12, B ： 13 - 17, C ： 18 - 20, D ：21 - 24, E ： 25-28, F：29-35, G：36-40, H：41 -65, and I：66 -81） （n =60, with 30 males and 30 females）. The height of each maxilla was measured. The results was analyzed by ANOVA with SPSS 14.0. RESULTS ： The height of maxillary alveolar bone showed no statistic difference between male and female in the same age groups （ P 〉 0.05 ）. The height of the alveolar bone in group A was higher than that in group B, it was increasing from group B to group E, then de- creased in group F, increased in group G and kept the similar level to group I. CONCLUSION ： The height of maxil- lary alveolar bone changes with age and reaches a stable state after 40 years of age.
