A method to compare cost-effectiveness of dental treatments: adhesive bridges compared to conventional bridges

The cost-effectiveness of a dental restoration depends primarily on the durability and the cost of the restoration. In this report a method is described to compare the cost-effectiveness using the durability data of adhesive bridges and conventional bridges. The study shows that, for the situation in the Netherlands, the breakeven point for equal cost-effectiveness compared to conventional bridges is achieved when the 50% survival for adhesive bridges is approximately 6.5 yr. Clinical data indicate a higher cost-effectiveness for anterior adhesive bridges. The method described in this report is considered to be useful for comparing cost-effectiveness of dental restorations in different situations.
