Objective: The objective of the study was to assess patient-reported preferences and outcomes in patients rehabilitated with both an implant-supported single crown (ISC) and a tooth-supported fixed dental prosthesis (FDP).
Materials and methods: The electronic journal system at the Faculty of Dentistry, University of Oslo, was searched to find patients presenting both an ISC and an FDP replacing no more than two teeth between abutments. Identified patients that agreed answered a questionnaire followed by a clinical examination. Descriptive statistics was calculated.
Results: Thirty patients were included. The mean function time was 11.8 years for FDPs and 6.6 years for ISCs. All but three patients were satisfied with both rehabilitation modalities. No patients were unsatisfied with aesthetics or function of either rehabilitation. All patients reported satisfactory function of their restorations and reported chewing without problems. The self-reported post-operative complications were few, but less than observed in the clinical examinations.
Conclusions: More patients reported food impaction with their FDP as compared to their ISC. Function and aesthetics of FDPs and ISCs were rated similarly, but more patients found the ISC treatment more uncomfortable. Despite this finding, most patients would prefer to undergo ISC treatment if they were to replace another missing tooth.
