Background. Peri-implant soft tissue health and esthetic is one of the main factors influencing the longterm survival and success of implants. While Platform-switched (PS) implants have been widely studied in terms of marginal bone preservation, the purpose of this study is to review the soft tissue conditions around these implants. Methods. Using pertinent keywords, PubMed and Embase databases were searched for relevant clinical studies which compared the peri-implant soft tissue outcomes of PS implants to the implants with matching diameter abutments. The quality of articles was evaluated using Cochrane Collaboration’ s tool for randomized controlled trials and Methodological Index for Non-Randomized Studies. Results. Eight clinical studies were selected to be reviewed. The articles varied in numerous features such as the implants’ brands, the duration of follow-up and the study quality. The evaluated peri-implant soft tissue parameters included the height or recession in buccal mucosa, height of the mesial and distal papilla, the mucosal thickness, and pink esthetic score. In all studies, PS implants showed better or at least similar results relative to the implants with flat-to-flat or conical connections. The difference between the test and control groups reached statistical significance in three of the reviewed articles. Conclusions. PS implants can provide peri-implant soft tissue health and stability and consequently acceptable clinical results.
