Secondary Trauma From Occlusion And Periodontitis

Secondary Trauma From Occlusion And Periodontitis

Write short note on secondary trauma from occlusion.
Answer. When tissue injury occurs due to normal or excessive occlusal forces applied to teeth with a reduced support it is called as secondary trauma from occlusion.

In secondary type of trauma from occlusion adaptive capacity of periodontium to withstand occlusal forces is impaired.

Periodontium is susceptible to injury and previously well-tolerated occlusal forces become traumatic, so that is why trauma from occlusion is considered as secondary cause of periodontal destruction.

Secondary Trauma From Occlusion Etiology

• Loss of alveolar bone because of marginal inflammation, which reduces periodontal attachment area.
• Systemic disorders reduce the resistance of tissue and forces previously tolerable increases.

Secondary Trauma From Occlusion Features

• Marginal periodontitis is present with reduced height of bone.
• When secondary trauma from occlusion superimposed with plaque-induced inflammation, it causes angular bone loss and infrabony pocket formation.
