Does Bruxism cause implant failure?

Bruxism has been identified as a significant factor contributing to dental implant failure. Several studies have investigated the relationship between bruxism and the success rates of dental implants, revealing that patients with bruxism experience higher rates of implant failure compared to non-bruxers.

A meta-analysis indicated that bruxers had a pooled odds ratio (OR) of 4.72 for implant failure when compared to non-bruxers, suggesting a substantial increase in risk. Another study found that the odds ratio of implant failure in bruxers was 2.71, highlighting the increased prevalence of mechanical complications and failures in this group.

The excessive occlusal forces generated by bruxism can lead to complications such as screw loosening, ceramic chipping, and overall higher rates of prosthesis failure. Specific protocols, including the use of occlusal splints or botulinum toxin injections, have been recommended to mitigate these risks before implant placement.

In summary, bruxism is a critical risk factor for dental implant failure, and careful evaluation and management strategies are essential for patients with this condition to improve their treatment outcomes.
