Between April 1, 1987 and August 7, 1997, a total of 128 abutment teeth associated with 34 telescope removable partial dentures in 28 patients (22 females and 6males) who had a mean age of 57.4±9.3 years was observed. The survival time (with extraction being the endpoint) for each abutment tooth was calculated using Kaplan-Meier analysis. Significance levels were determined using 8 prognostic factors for 4 statistical tests, i. e., the generalized Wilcoxon, the Cox-Mantel, the Logrank, and the Mantel-Haenszel tests. Furthermore, survival estimates and relative risks were calculated by Cox hazard regression.<BR>The results conclusively indicated a higher survival for vital as compared to endodontically-treated teeth. The relative risk of an abutment tooth adjacent to a free-end saddle was 5.81. The risk increased by 2.79 for each group from molar to cuspid, to premolar, and to incisor. The survival estimate was 89.8% at 9-10 years after placement of the denture.
