What is the definition of ankylosis in dental terms?

Ankylosis in dental terms refers to the fusion of cementum and alveolar bone, which can lead to the immobilization of a tooth within its socket. This condition typically results from periodontal disease or trauma and can affect a tooth's ability to function normally. In cases of ankylosis, the affected tooth may not erupt properly and may be at risk of being lost, as it is directly fused to the surrounding bone rather than being held in place by the periodontal ligament. This definition encompasses the key aspects of how ankylosis impacts dental health and the structural integrity of teeth. Understanding this condition is crucial for dental professionals in diagnosing and planning appropriate treatments for affected patients.
