Abstract

Supporting a Removable Partial Denture (RPD) with implants can be beneficial to the many shortcomings associated with conventional RPD treatment. However it is also quite likely to increase treatment costs. The aim of this study was to conduct a cost-effectiveness analysis comparing conventional RPD and Implant Supported Removable Partial Denture (ISRPD) treatment in patients with a bilateral free-ending situation in the mandible. Eleven patients were included, a new RPD was made and implant support was provided 3 months later. Opportunity costs and costs based on the national tariff structure where determined and compared to 3 outcome measures: oral health related quality of life measured using the OHIPNL49, a chewing ability test (Mixing Index) and perceived general health (SF-36) which was subsequently converted into Quality-adjusted Life Year’s (QALY’s). Outcome measures where determined at 3 moments in time: baseline (To), after having worn a newly made conventional RPD for 3 months (T1) and 3 months after the provision of implant support to the RPD (T2). Results strongly depend on choice of outcome measure. When SF-36 is used as an outcome measure no incremental effect and thus added value was found. When MI or OHIP are used as outcome measures implant supported RPD’s provide better outcomes. A minimal importance difference (MID) is only known for OHIP, making clinical relevance of MI difficult to determine. Considering the clinical relevance of the gain in oral health related quality of life, supporting a RPD with implants is cost effective when a monetary threshold exceeding than €130 per OHIP point gained is adopted.
