Failure of dental bridges. I. Age and sex of patients and distribution of replaced and abutment teeth

In this study, 156 dental bridges, constructed in 132 randomly selected patients were evaluated. There was no significant difference between the number of bridges placed in males and the number placed in females. However, the results revealed that the maxillary arch received more prostheses than the mandibular arch. The most-frequently replaced teeth were the mandibular first molars and the least-frequently replaced were mandibular canines. Maxillary second premolars, the mandibular second premolars and the mandibular second molars were the most frequent teeth used as abutments.
