What does 'protrusive movements' describe?

Protrusive movements refer to the action of thrusting the lower jaw forward. This movement is crucial in various dental functions, such as during certain dental procedures and when assessing occlusion and jaw alignment. In the context of jaw movement, protrusive movements specifically indicate how the mandible moves in a forward direction, which can be significant in evaluating function, aesthetics, and fitting of dental appliances.

Understanding this movement is essential for expanded function dental assistants, as it plays a critical role in the assessment of temporomandibular joint (TMJ) disorders, occlusal adjustments, and ensuring proper fitting and function of dental restorations. Protrusive movements contribute to the overall biomechanics of the mouth and jaw, and recognizing these movements is fundamental to providing comprehensive patient care.
