Based on the number of previous dentures and on the information given by the patients the authors describes a mathematical model for the estimation of the denture survival time. The distribution of edentulousness according to age (based on 9991 patients) shows a regular pattern and can be described by a second degree function. The survival time shows a similar regularity. The application of the Kaplan-Meier method can be used to estimate the survival time calculated only from a single cross-sectional study. This approach uses the survival time of the first set of complete dentures and the average edentulous time of the patients with their second complete dentures as a base for the calculation.
