To evaluate the oral health-related quality of life (OHRQoL) of implant-retained overdenture users.
63 patients aged 50-90 years treated with at least one implant overdenture at the Complutense University (Madrid) in 2000-2010 were included. Of those, 42 answered the Oral Health Impact Profile (OHIP-14 sp) questionnaire. The additive method was used in the OHIP analysis. Data regarding sociodemographic background, overdenture features, and clinical factors were recorded. Sociodemographic and overdenture-related variables for the lost patients (n=21) were also gathered from their history files. Descriptive probes, Mann-Whitney and Kruskal-Wallis tests, and the Spearman correlation coefficient were applied (p ≤ 0.05).
The predominant participants' profile was that of a 71-80-year-old woman wearing a mandibular overdenture with a bar retention system and a complete denture in the opposite jaw. 71.4% of the respondents suffered from some kind of impact on OHRQoL, showing an average score of 2.7 ± 3.0 (range: 0-13). 100% of respondents reported no impact for the "social disability" and "handicap" dimensions. The most prevalently affected domain was "physical pain", followed by "functional limitation" and "psychological discomfort". Variables such as the overdenture location or the retention system affected specific OHIP subscales (p ≤ 0.05). The greatest total score was achieved when the antagonist was a complete denture (p<0.01).
Implant-retained overdentures provide a seemingly acceptable quality of life in the elderly population studied, irrespective of the influence of the location, retention system, and antagonist.
Although further research is necessary, mandibular implant overdentures are more comfortable than maxillary ones. Ball-retained prostheses facilitate eating the most, whereas the presence of oral ulcers and/or candidiasis was only detected in the case of bars, thus impairing OHRQoL. A complete denture as antagonist decreases the patient overall satisfaction.
评估种植体支持覆盖义齿使用者的口腔健康相关生活质量（OHRQoL）。
纳入 2000-2010 年在马德里Complutense 大学接受至少一枚种植体覆盖义齿治疗的 63 名 50-90 岁患者。其中 42 名患者回答了口腔健康影响简表（OHIP-14 sp）问卷。OHIP 分析采用加和法。记录社会人口统计学背景、覆盖义齿特征和临床因素的数据。还从失访患者（n=21）的病史档案中收集与社会人口统计学和覆盖义齿相关的变量。应用描述性探针、Mann-Whitney 和 Kruskal-Wallis 检验以及Spearman 相关系数（p≤0.05）。
主要参与者的特征是 71-80 岁的女性，佩戴下颌带杆固位覆盖义齿，对颌为全口义齿。71.4%的受访者在 OHRQoL 方面受到某种影响，平均得分为 2.7±3.0（范围：0-13）。100%的受访者报告“社会障碍”和“障碍”维度无影响。受影响最严重的领域是“身体疼痛”，其次是“功能受限”和“心理不适”。覆盖义齿位置或固位系统等变量会影响特定的 OHIP 亚量表（p≤0.05）。当对颌为全口义齿时，总得分最高（p<0.01）。
种植体支持覆盖义齿为研究中的老年人群提供了看似可接受的生活质量，无论位置、固位系统和对颌情况如何。
尽管需要进一步研究，但下颌种植体覆盖义齿比上颌覆盖义齿更舒适。球型固位体最有利于进食，而只有在使用杆固位系统时才会出现口腔溃疡和/或念珠菌病，从而影响 OHRQoL。全口义齿作为对颌会降低患者的总体满意度。
