To evaluate the reduction of residual alveolar ridge height on panoramic radiographs and the differences between denture wearers and non-denture wearers.
The study consisted of 147 individuals (74 men and 73 women) [50 were denture wearers and 50 non-denture wearers (examination groups) and 47 of them were dentate (control group)]. Individuals having diseases impacting on bone were excluded. Vertical measurements were made at 15 sites (central incisors, first premolars and molars at the left and right of both jaws and the distance between the zygoma/orbit). MANOVA (multi-variate analysis of variation) was used for the statistical analysis of the results.
There were significant differences between the alveolar ridge heights of dentate and edentulous groups (p < 0.001). Between the denture wearer and the non-denture wearer groups, there was significant difference in the lower jaw (p < 0.001), but no significant difference in the upper jaw (p = 0.635). There were also differences between men and women (p < 0.005) and upper and lower jaws at every measurement sites (p < 0.01).
Reduction in residual alveolar ridge height was in close relation with gender, denture usage and edentulousness.
评估全景片上剩余牙槽嵴高度的降低情况，以及义齿佩戴者和非义齿佩戴者之间的差异。
本研究共纳入 147 名个体（74 名男性和 73 名女性）[50 名义齿佩戴者和 50 名非义齿佩戴者（实验组），其中 47 名有牙（对照组）]。排除患有影响骨骼疾病的个体。在 15 个部位（左右两侧的中切牙、第一前磨牙和磨牙，以及颧骨/眼眶之间的距离）进行垂直测量。采用多变量方差分析（MANOVA）对结果进行统计分析。
有牙组和无牙组的牙槽嵴高度存在显著差异（p<0.001）。在义齿佩戴者和非义齿佩戴者组之间，下颌存在显著差异（p<0.001），而上颌则无显著差异（p=0.635）。男性和女性之间也存在差异（p<0.005），以及每个测量部位的上颌和下颌之间也存在差异（p<0.01）。
剩余牙槽嵴高度的降低与性别、义齿使用和无牙状态密切相关。
