Influence of occlusal interferences on the periodontium in patients treated with fixed prosthesis.
Gingival bleeding, pocket depth, and tooth mobility were recorded, and occlusal analyses were made on 147 subjects treated with fixed prostheses placed 4 years earlier. The percent of gingival bleeding was greater in teeth with interferences than in those without interferences. A slight increase in pocket depth was found in connection with interferences. However, the difference was statistically significant only in the group with no preprosthetic treatment. No differences in tooth mobility were found between teeth with and those without interferences, possibly partly because of the splinting influence of the fixed partial dentures on the mobile teeth.
