Abstract

This study was to compare the patients wearing comfortable distally extending cantilever bridges (DECBs) with those having discomfortable ones, in the aspect of the periodontal condition & prosthodontic status. The subjects in the present study were 164 patients appointed to Seoul National University Dental Hospital. One group was consisted of 101 patients wearing comfortable DECBs and the other group were made of 64 patients who had felt discomfort. On clinical parameters, there were no significant difference between 2 groups in plaque index, tooth mobility & probing depth, but gingival index was higher in group wearing discomfortable DECBs. In prosthodontic status, the ratio of pontic oversize was higher in the group of discomfortable DECBs, but there were no significant difference in the view of crown overcontour, overhanging margin & interproximal space closure between 2groups. This study failed to clarify causal factors of discomfortable DECBs.
