What is a consideration when using a complete ceramic crown in patients with bruxism?

When considering the use of a complete ceramic crown in patients with bruxism, the increased risk of fracture is a significant concern. Bruxism involves grinding and clenching of teeth, which generates substantial forces that can exceed the material's strength limit in the case of ceramic crowns. Ceramic materials, while offering excellent esthetics and biocompatibility, can be brittle and may not withstand the repeated stress associated with bruxism, leading to cracks or complete fractures of the crown.

This risk is compounded in patients who are known to exhibit significant tooth wear or have a history of breakage with dental restorations. As such, it is crucial for clinicians to assess the occlusal patterns and forces involved in bruxism before opting for complete ceramic crowns for these patients. Strategies such as using more resilient materials or protective night guards may also be considered to mitigate these risks.
