The etiology of denture stomatitis remains controversial. Trauma due to unstable dentures has been suggested as an etiological factor. Therefore, we tested the hypothesis that the prevalence of denture stomatitis is reduced when mandibular dentures are stabilized by implants. Data were collected at a one-year follow-up from 173 edentulous elders who had randomly received mandibular implant overdentures or conventional dentures. The diagnosis of denture stomatitis was determined according to the Newton classification. Elders wearing conventional dentures were almost 5 times more likely to have denture stomatitis than those wearing mandibular two-implant overdentures (P < 0.0001, Fisher's exact test). Adjusted odds ratios showed that only the type of the prosthesis (AOR = 4.54, 95% CI 2.20 to 9.40) and nocturnal wear (AOR = 3.03, 95% CI 1.24 to 7.40) predict the frequency of denture stomatitis. Thus, implant overdentures may reduce oral mucosal trauma and control denture stomatitis.
义齿性口炎的病因仍存在争议。不稳定义齿导致的创伤被认为是一个病因。因此，我们检验了以下假设：通过种植体稳定下颌义齿时，义齿性口炎的患病率会降低。在一项为期一年的随访中，我们收集了173名无牙颌老年人的数据，这些老年人随机接受了下颌种植覆盖义齿或传统义齿。义齿性口炎的诊断根据牛顿分类法确定。佩戴传统义齿的老年人患义齿性口炎的可能性几乎是佩戴下颌双种植体覆盖义齿老年人的5倍（P < 0.0001，Fisher精确检验）。调整后的优势比显示，只有修复体类型（AOR = 4.54，95% CI 2.20至9.40）和夜间佩戴（AOR = 3.03，95% CI 1.24至7.40）可预测义齿性口炎的发生频率。因此，种植覆盖义齿可能会减少口腔黏膜创伤并控制义齿性口炎。
