To assess and compare patient satisfaction and oral health-related quality of life (OHQOL) in patients treated with implant-supported overdentures and complete implant fixed prostheses.
From a database of patients who had undergone implant treatment over a 6-year period, a study population of 62 patients was identified; every patient had at least four implants placed in one edentulous arch and was restored with either an overdenture or a fixed prosthesis. Patients were examined and a self-administered, structured multiple-response questionnaire, including the Oral Health Impact Profile-14 measurement tool and a patient satisfaction survey, was used to evaluate patient-centered treatment outcomes.
Generally, patient satisfaction was very high in both the implant overdenture and fixed prosthesis groups, although the subjects in the overdenture group, who had mostly maxillary prostheses, reported significantly lower overall satisfaction and lower satisfaction with chewing capacity and esthetics. In just three categories--cost, satisfaction with treating doctor, and ability to perform oral hygiene measures--the fixed prosthesis group was less satisfied than the removable overdenture group, but the difference was not significant. Similarly, the overall OHQOL was high, although patients receiving a fixed prosthesis demonstrated significantly lower psychologic discomfort and psychological disability compared to the overdenture group.
Among all patients who had similar numbers of implants placed, those who received an implant overdenture were less satisfied and had lower OHQOL than the patients who had a fixed prosthesis. Since patient and dentist preferences influenced the type of prosthesis provided, it is likely that subjective, patient-related factors are major determinants of satisfaction and treatment outcomes.
评估和比较种植体支持的覆盖义齿和完全种植体固定修复体治疗患者的患者满意度和口腔健康相关生活质量（OHQOL）。
从一项为期 6 年的患者接受种植治疗的数据库中，确定了一个 62 名患者的研究人群；每位患者至少在一个无牙弓中植入了四颗种植体，并采用覆盖义齿或固定修复体进行修复。对患者进行检查，并使用自我管理的结构化多响应问卷，包括口腔健康影响概况-14 测量工具和患者满意度调查，来评估以患者为中心的治疗结果。
总体而言，种植体覆盖义齿和固定修复体组的患者满意度都非常高，尽管覆盖义齿组的患者（大多为上颌义齿）报告的总体满意度和对咀嚼能力以及美观的满意度明显较低。仅在三个类别（成本、对治疗医生的满意度和进行口腔卫生措施的能力）中，固定修复体组的满意度低于可摘戴覆盖义齿组，但差异无统计学意义。同样，总体 OHQOL 较高，尽管接受固定修复体的患者在心理不适和心理残疾方面明显低于覆盖义齿组。
在接受相同数量种植体植入的所有患者中，接受种植覆盖义齿的患者的满意度和 OHQOL 低于接受固定修复体的患者。由于患者和牙医的偏好影响了假体的类型，因此主观的、与患者相关的因素很可能是满意度和治疗结果的主要决定因素。
