Occlusal trauma
（重定向自Occlusal traumatism）
Occlusal trauma is a dental term that refers to the damage incurred when teeth are left in traumatic occlusion without proper treatment.
When the maxillary and mandibular dental arches approach each together, as they do, for example, during chewing or at rest, the relationship between the opposing teeth is referred to as occlusion. If this occlusal relationship is not balanced properly it may result in pain, tenderness and even mobility of the affected teeth.
