To investigate the impact of the retention system (screwed or cemented) of implant fixed dental prostheses (i-FDPs) on the peri-implant health, prosthesis' state, patient self-evaluation of functionality and aesthetics, and oral health-related quality of life (OHRQoL).
35 participants were classified into two groups according to the retention system of their metal-ceramic i-FDPs. For the analysis of peri-implant health and prosthetic complications, the implant units were individually assessed. Group 1 (SPD; n = 22): implant units for screwed i-FDPs; and Group 2 (CPD; n = 36): implant units for cemented i-FDPs. Data related to socio-demographics, design and installation of the superstructures, peri-implant condition, prosthetic complications, functionality, and aesthetics, were gathered. Patients answered the Oral Health Impact Profile (OHIP-14sp) questionnaire. Descriptive and parametric probes were run to evaluate the impact scores considering the study variables (α = 0.05).
The plaque index, gingival index, functionality, aesthetics, and global evaluation made by the patient recorded significantly better results for the SPD group. The most affected OHIP-14sp domain was 'Physical pain', followed by 'Psychological discomfort', and 'Functional limitation'. The subscales: 'Functional limitation', 'Physical disability', and 'Social disability', attributed significantly worst OHRQoL to CPD users.
A major presence of peri-implant disease, together with a worse functionality, aesthetics, and patient satisfaction were recorded in cemented i-FDPs with respect to the screwed ones.
The retention system of i-FDPs can impact the peri-implant health, the subjective functional and aesthetic evaluation of the restoration, and the patients' OHRQoL; the screw retention providing superior results than the cementation.
研究种植体固定修复体（i-FDPs）的固位系统（螺丝固位或粘结固位）对种植体周围健康、修复体状态、患者对功能和美观的自我评估以及口腔健康相关生活质量（OHRQoL）的影响。
根据金属陶瓷 i-FDPs 的固位系统，将 35 名参与者分为两组。为了分析种植体周围健康和修复体并发症，对每个种植体单位进行评估。第 1 组（SPD；n=22）：螺丝固位 i-FDPs 的种植体单位；第 2 组（CPD；n=36）：粘结固位 i-FDPs 的种植体单位。收集了社会人口统计学、上部结构的设计和安装、种植体周围状况、修复体并发症、功能和美观相关的数据。患者回答口腔健康影响量表（OHIP-14sp）问卷。考虑研究变量（α=0.05），进行了描述性和参数探测，以评估影响评分。
SPD 组的菌斑指数、牙龈指数、功能、美观和患者总体评价记录的结果明显更好。受影响最严重的 OHIP-14sp 领域是“身体疼痛”，其次是“心理不适”和“功能受限”。“功能受限”、“身体残疾”和“社会残疾”等亚量表对 CPD 用户的 OHRQoL 评价最差。
与螺丝固位的 i-FDPs 相比，粘结固位的 i-FDPs 种植体周围疾病的发生率更高，功能、美观和患者满意度更差。
i-FDPs 的固位系统会影响种植体周围健康、修复体的主观功能和美观评估以及患者的 OHRQoL；螺丝固位比粘结固位效果更好。
