Impact of the retention system of implant fixed dental restorations on the peri-implant health, state of the prosthesis, and patients' oral health-related quality of life. J Dent. 2020 Mar;94:103298. doi: 10.1016/j.jdent.2020.1032980300-571210.1016/j.jdent.2020.103298https://hdl.handle.net/20.500.14352/113255Objectives: 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). Methods: 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). Results: 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. Conclusion: 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. Clinical significance: 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.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article1879-176Xhttp://dx.doi.org/10.1016/j.jdent.2020.10329832067997https://www.sciencedirect.com/science/article/abs/pii/S030057122030035X?via%3Dihubopen access616.314-089.843: 616.314-089.28616.314-089.28:616.314-089.843Cemented implant-supported partial prosthesesImplant fixed dental prostheses (i-FDPs)Oral health impact profile (OHIP)Oral health-related quality of life (OHRQoL)Peri-implant healthScrewed implant-supported partial prosthesesOdontología (Odontología)Prótesis dentalImplantes dentales3213.13 Ortodoncia-Estomatología3314.02 Prótesis3213.04 Cirugía de Huesos
