This review evaluated the change in treatment outcomes after conversion from conventional removable partial denture (RPD) to implant-assisted removable partial denture (IARPD). The patient-reported outcome measures (PROMs), objective parameters for evaluation of functional performance, and biological and mechanical complication were evaluated.


This systematic review was based on the Cochrane review methodology and followed the criteria of the preferred reporting items for systematic reviews and meta-analyses (PRISMA). We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science and Scopus up to April 3, 2019. After the initial search, additional electronic and hand searches were performed to identify further studies, ongoing studies and gray literature, without restrictions on language, year of publication or publication type.


In total, 6,544 non-duplicate articles were identified, and 31 were eligible for full-text search. Finally, 19 publications based on 13 independent studies were selected. In the meta-analysis, general patient satisfaction was significantly increased (p < .05), and the improved mastication was remarkable oral function. In oral health-related quality of life, the oral health impact profile score was significantly improved, and improvements of physical pain and psychological disability were prominent (p < .05). Masticatory performance was improved in terms of maximum bite force, active occlusal contact area, and mandibular jaw movement (p < .05). The weighted mean survival rate of implants was 96.60%.


After conversion from conventional RPD to IARPD, the PROMs and masticatory performance significantly improved in partially edentulous patients under mandibular Kennedy classification Ⅰ.
