Parafunction refers to habitual jaw activities such as teeth grinding and clenching. Which category does parafunction belong to as a TMD risk factor?

Explanation:
Parafunction is a category that specifically covers habitual nonfunctional jaw activities, like grinding and clenching. These activities place extra load on the jaw muscles and the temporomandibular joint, increasing the risk of TMD symptoms. Because the question asks which category parafunction fits into, the best answer is the parafunctional category itself—it’s a distinct domain that describes these habits, separate from posture (body alignment), occlusion (tooth contact and bite relationships), or stress (psychosocial factors).
