Table 4 In addition to the cost calculation based on composite survival rates of 15 or 31 years (Table 3), the same cost calculations were repeated with a reduced median time until need for repair (i. e., 5 years / 60 months, or 10 years / 120 months, respectively), in order to give an idea of expected costs for shorter repair intervals for composite restorations. Other than that, identical settings of dental fee increment factors (GOZ 2.3, or 3.5) and treatment fees (in Eur) have been used
