Impact of Bruxism on Defects in Implant–Borne Dental Prostheses: Summary

Ceramic veneer fracture poses as a frequent complication in implant-borne fixed restorations in prosthetic Dentistry. The absence of mechanoreceptors around implants, and lack of pulp receptors, decrease “tactile sensitivity” therefore presenting unmanageable forces from mastication and excess stress on the implant. These forces surge a sizable amount in bruxers, or people who grind their teeth.

This retrospective clinical study was done to determine any ceramic veneer fractures and decide if there was any correlation between bruxism and demographic/ clinical parameters in patients being rehabilitated at a collection of dental programs.

Materials and Methods

507 implant- borne fixed units between 1996 and 2011 were analyzed. A total of 144 patients with these fixed units were examined. There were four defect groups, each patient assigned to one, according to extent and position of the implant. In this study, a hypothetical correlation between bruxism and ceramic veneer fractures was done.


69 of the 144 contributors were diagnosed with signs of bruxism. The prevalence of fractures was significantly increased when there were signs of bruxism. Bruxers were 3.6 times more likely than non bruxers in having ceramic fractures.


According to the results of the study it can be concluded that bruxism poses as a hazard to ceramic veneer fractures in implant borne fixed dental prostheses.
