[Prognosis of abutment teeth in severely reduced residual dentitions]

The survival rate of 2094 abutment teeth in 671 removable partial denture cases was analysed. Within an interval of 2-7 years 150 abutments were lost. The survival-rate of abutments in severely reduced dentitions differs significantly from that in dentitions with more than 3 teeth. Regarding the framework design there was no significant difference in the survival-rate of abutment teeth for removable partial dentures supported by more than 3 teeth.
