Quick Reference

Abnormal occlusal contacts resulting in damage to the periodontium (periodontal traumatism) or other supporting structures. Occlusal trauma has been investigated in relation to the progression of periodontal disease. Studies do not support the role of occlusal trauma in the healthy, plaque-free dentition; there is evidence to suggest that occlusal trauma may be a risk factor for disease progression in the periodontium with established periodontitis. Diagnostic features include tooth mobility, tooth migration, discomfort on chewing or tooth percussion, muscle tenderness, excessive occlusal wear facets, chipped teeth, fremitus, and radiographically visible widening of the periodontal ligament space.
