dc.description.abstract PURPOSE: This study evaluated outcome and quality of treatments with telescopic crownretained dentures. MATERIALS AND METH-ODS: A total of 72 subjects (27 men and 45 women; mean age 67 years) wearing 75 telescopic crown-retained dentures (18 in the man-dible and 57 in the maxilla) participated in the study. There were a to-tal of 368 abutment teeth, 272 in the maxilla and 96 in the mandible. Each patient was clinically examined. Using the CDA evaluation sys-tem, four calibrated evaluators also examined, independently, the in-ner crowns for margin integrity and the superstructure for retention, occlusion, stability, wear, and esthetic appearance. Observer consis-tency was measured with Cohen’s kappa. RESULTS: Tbe observation period varied from 9 months to 9.3 years (mean 3.8 years) One tele-scopic crownretained denture was lost, and 24 abutment teeth (7%) were extracted during the observation period. In 49 abutment teeth (13%), technical complications had occurred, and a total of four framework fractures (5%) were observed. Based on the CDA criteria, most of the characteristics were evaluated as satisfactory. The charac-teristics “condition of denturesupporting soft tissue” and “superstruc-ture wear” showed the highest frequencies of not acceptable ratings, 44% and 45%, respectivly. CONCLUSION: In this retrospective fol-lowup study, satisfactory outcome was found for tooth-supported telescopic crown-retained dentures over a mean observation period of 3.8 years. en
