Abstract Statement of problem Guidance to determine whether providing an interim implant-supported restoration is beneficial is lacking. Purpose The purpose of this systematic review was to answer the following focused question: “Does the use of interim fixed implant prostheses before placement of a definitive fixed implant-supported prostheses impact esthetics, peri-implant health, and osseointegration in partially dentate adults?” Material and methods A search of electronic databases (Medline and Embase) and the nonpeer-reviewed literature for randomized controlled trials, systematic reviews, and cohort studies in the English language was conducted. Results Two studies met the eligibility criteria. Heterogeneity of the study methodologies and outcome measures did not allow for meta-analysis. Use of interim implant-supported restorations may improve the esthetic outcome. Occlusal loading of definitive implant-supported prosthesis without the use of an interim restoration may decrease chair time and the number of patient visits. Conclusions The systematic review has found insufficient evidence to support or refute the practice of providing an interim restoration before delivering an implant-supported prosthesis. Clinical Implications There is currently insufficient evidence to provide clear recommendations on the use of fixed interim implant-supported restorations; further research is required.
