Occlusion is a common cause of TMD.

• A. True
• B. Not known
• C. False
• D. Depends on occlusal pattern

Answer: (C)

Occlusion is not a common cause of temporomandibular disorders. TMD arises from multiple interacting factors, including muscle tension, disc displacement, joint pathology, trauma, parafunctional habits, stress, and posture. Occlusal relationships can influence jaw movement and may be associated with symptoms in some people, but large studies do not show a consistent, strong link between occlusal patterns and the development of TMD. Many individuals with noticeable malocclusion have no TMD, while others with normal occlusion do experience TMD. Because of this, occlusion is not regarded as the primary etiologic factor. In practice, occlusal considerations may be relevant in certain cases, but broad occlusal treatment is not universally indicated or proven to be a cure for TMD. Focus tends to be on pain mechanisms, parafunctional activity, psychosocial factors, and joint health, with treatment tailored to the individual’s diagnostic findings.
