| 内容記述 | Aims: The present study aimed to calculate the incremental cost-effectiveness ratio (ICER) by performing cost–utility analysis on implants, insurance fixed dental prostheses (IFDPs) and private fixed dental prostheses (PFDPs) for a single missing intermediate molar. Methods: In this model study, transition probability was used based on the results of past research, and the Markov model was used for analysis. To analyse sensitivity, Monte Carlo simulations were performed. In September 2017, the utility values for various types of missing teeth were collected, and dental prosthetic treatment was performed in general members of the Japanese population adjusted by sex and age. The time trade-off (TTO) method, an index scale (0-1), was used for measuring the utility values. Results: The utility value was the highest when measured at the state in which implant treatment was performed and the lowest when measured in the untreated missing-tooth state. This model showed that compared to fixed dental prostheses (FDPs), selecting implants resulted in higher quality-adjusted life years (QALYs). However, the estimated cost for 30 years was lower for IFDPs. The results also showed that PFDPs were in a more extended, dominant state than IFDPs and implants. The implant-to-IFDP ICER was €2454.37. Conclusion: Our results suggested that implants can be used to obtain more utility values in comparison to IFDPs and PFDPs. The ICER threshold for 1 QALY in Japan is approximately €37,037–€44,444, and the implant-to-IFDP ICER was found to be below that found in this study. Accordingly, it appears that implants offer superior cost-effectiveness. |
