To quantify the impact of edentulousness on residual ridge volume, denture stomatitis (DS), as well as oral health behaviours among geriatric denture-wearers.
Residual ridge resorption (RRR) is the primary intraoral complication of complete edentulism, but individual variation among geriatric patients has been observed.
Data collection relied upon a 10-year retrospective chart review of all complete denture-wearing geriatric patients presenting at the Removable Prosthodontics Clinic, Dental School of Athens, between 1993 and 2002. Analyses relied on descriptive, bivariate, and multivariate methods based on ordinal logistic regression.
A total of 873 records of geriatric patients (age mean = 72; median = 70; range = 65-95) comprised our analytical sample. Subjects' mean (SD) time since edentulation was 7.7 (10.2) years. Eleven percent were diagnosed with temporomandibular disorder (TMD). While 28% of patients reported cleaning their dentures at least daily, 6% presented with denture stomatitis (DS). Each added year of edentulism increased the odds of mandibular RRR: OR (95% CI) = 1.05 (1.03, 1.07). Nightly denture wear was the strongest risk factor for DS. Finally, independent of age and sex, each year of being edentulous increased the odds of presenting with TMD: OR (95% CI) = 1.03 (1.01, 1.05).
Time since edentulation was strongly associated with mandibular but not maxillary RRR, as well as TMD development.
定量研究无牙颌对老年义齿佩戴者剩余牙槽嵴体积、义齿性口炎（DS）以及口腔健康行为的影响。
剩余牙槽嵴吸收（RRR）是全口无牙颌的主要口腔内并发症，但在老年患者中观察到个体差异。
数据收集依赖于对 1993 年至 2002 年期间在雅典牙科学院可摘局部义齿诊所就诊的所有全口义齿佩戴老年患者的 10 年回顾性图表审查。分析依赖于基于有序逻辑回归的描述性、双变量和多变量方法。
我们的分析样本包括 873 名老年患者（年龄平均值=72；中位数=70；范围=65-95）的记录。患者无牙时间的平均（SD）为 7.7（10.2）年。11%的患者被诊断为颞下颌关节紊乱（TMD）。虽然 28%的患者报告每天至少清洁义齿一次，但 6%的患者出现义齿性口炎（DS）。每增加一年无牙，下颌 RRR 的几率增加：OR（95%CI）=1.05（1.03，1.07）。夜间佩戴义齿是 DS 的最强危险因素。最后，无论年龄和性别如何，每无牙一年都会增加出现 TMD 的几率：OR（95%CI）=1.03（1.01，1.05）。
无牙时间与下颌而非上颌 RRR 以及 TMD 的发展密切相关。
