Glass hybrid cost effective option for restoring permanent molars, reveals study

Using Markov modelling, the authors followed molars over the lifetime of an initially 12-years-old individual. Our health outcome was the time a tooth was retained, explained the lead author.

A mixed-payers' perspective within German healthcare was used to determine costs (in Euro 2018) using fee item catalogues. Monte-Carlo-microsimulations, univariate and probabilistic sensitivity analyses were conducted. Incremental cost-effectiveness ratios (ICER)s and cost-effectiveness-acceptability were quantified.

The results showed that in the base-case scenario, composite was more effective (tooth retention for a mean (SD) 54.4 (1.7) years) but also more costly (694 (54) Euro) than glass hybrid (53.9 (1.7) years; 614 (56 Euro). The ICER was 158 Euro/year, i.e. payers needed to be willing to invest 158 Euro per additional year of tooth retention when using composite. In a sensitivity analysis, this finding was confirmed or glass hybrid found more effective and less costly.

As a result, it was concluded that composite was more costly and limitedly more effective than glass hybrid, and while there is uncertainty around our findings, glass hybrid is likely a cost-effectiveness option for restoring permanent molars.
