A meta-analysis of durability data on conventional fixed bridges

Abstract A meta-analysis was performed on the dental literature since 1970, presenting clinical data of conventional bridges. 42 publications were found that contained durability data of conventional fixed bridges. These publications dealt with 33 different samples. According to the exclusion criteria 26 studies were excluded for the meta-analysis. The data of 4118 conventional bridges were analyzed. The calculated overall survival rate was 74.0 ± 2.1% after 15 yr.
