Objective: To assess the longitudinal changes in oral health-related quality of life (OHRQoL) and the denture satisfaction of immediate rehabilitation by implant-supported full-arch prostheses in patients of the edentulous and potential edentulous jaws. Methods: Patients in the Department of Implantology, Peking University School and Hospital of Stomatology from April 2008 to November 2020 were enrolled in the study. The treatment group (TG) consisted of 73 patients who had been treated with immediate rehabilitation by using implant-supported full-arch prostheses while the control group (CG) consisted of 31 patients who would be treated with immediate rehabilitation of implant-supported full-arch prostheses. The mean age of the patients in the treatment group was (57.5±11.1) years (ranged 31-79) and the average follow-up duration was 5.5±2.9 years (ranged 1-12). The OHRQL ratings were collected using oral health impact profile-20 (OHIP-20) and the visual analogue scales (VAS) was used to assess the denture satisfaction including stability, aesthetics, mastication, ease of cleaning, speaking and general satisfaction. Independent t-test, Mann-Whitney U-test and locally weighted scatterplot smoothing were applied for data analysis. Results: The cumulative survival rate (CSR) of the implants was 97.6% (450/461). The CSR of the prostheses was 93.3% (98/105). The average peri-implant marginal bone loss (MBL) was (0.8±0.4) mm and (1.2±0.6) mm after 1 and 5 years, respectively. The mean OHIP-20 total scores of TG and CG were 5(7) and 32.9±12.6, respectively, which had statistical difference between the two groups (P<0.001). The general satisfaction in the TG was 95.0(10.0), while the higher scores were for chewing [100.0(7.5)] stability [100.0(10.0)] and esthetics [100.0(10.0)] and the lower scores were for ease of cleaning [85.0(25.0)] and speaking ability [100.0(12.5)]. With prolonged follow-up, the total OHIP-20 score decreased significantly at first and then remained stable with minor fluctuations. Conclusions: Based on the present study, immediate rehabilitation with implant-supported full-arch prostheses was a feasible treatment program that had a long-term positive impact on OHRQoL, provided strong psychological and sociological support to the patients and restored the chewing and speech functions effectively.
目的： 追踪观察全牙弓种植即刻固定修复1至12年后患者的口腔健康相关生活质量（oral health-related quality of life，OHRQoL）以及义齿满意度。 方法： 选取2008年10月至2020年11月于北京大学口腔医学院·口腔医院种植中心就诊的73例行全牙弓种植即刻固定修复的无牙颌或潜在无牙颌患者（治疗组）和31例未行全牙弓种植即刻固定修复的无牙颌或潜在无牙颌患者（非治疗组）。采用口腔健康影响量表-20（oral health impact profile-20，OHIP-20）和视觉模拟量表评价患者OHRQoL和义齿满意度，其中满意度包括稳固、美观、咀嚼、言语、易清洁和总体的方面。采用独立样本t检验、Mann-Whitney U检验、局部加权回归散点平滑法统计。 结果： 治疗组患者年龄为（57.5±11.1）岁（31~79岁），随访时间为（5.5±2.9）年（1~12年），种植体累积存留率为97.6%（450/461），修复体累积存留率为93.3%（98/105），1年种植体边缘骨吸收为（0.8±0.4）mm，5年种植体边缘骨吸收为（1.2±0.6）mm。治疗组患者OHIP-20总分［5（7）分］显著低于非治疗组患者［（32.9±12.6）分］（Z=7.454，P<0.001）。治疗组患者义齿总体满意度为95.0（10.0）分，其中咀嚼［100.0（7.5）分］、稳固［100.0（10.0）分］和美观［100.0（10.0）分］评分较高，易清洁［85.0（25.0）分］和言语［100.0（12.5）分评分较低。随观察时间的延长，治疗组患者的OHIP-20总分先下降，随后在波动中长期保持稳定。 结论： 基于本研究结果，全牙弓种植即刻固定修复是一种可行的治疗方案，可长期对患者OHRQoL产生积极影响，从功能上有效恢复咀嚼、言语作用，从心理、社会功能上提供给患者有力的支持。.
