Anterior limit of mandibular movements is defined by which statement?

Anterior limit of mandibular movements is defined by which statement?

• A. Condyles Undergo a Twisting Around the Insertion of the Temporo-Mandibular Ligaments
• B. Condyles Are Located in the Highest and Posterior Portion of the Glenoid Cavity
• C. Condyles Are Located Below and Anteriorly to the Glenoid Cavity
• D. The Mandible Is in Centric Relation

Answer: (A)

The anterior limit of mandibular movement is set by the way the condyle moves forward within the glenoid fossa while being constrained by the ligaments that attach around the joint. As the mandible translates anteriorly during protrusion, the condyle not only slides along the articular eminence but also twists around the insertion points of the temporomandibular ligaments. This twisting acts as a pivot, limiting further forward displacement and establishing the forward boundary of movement. The other descriptions place the condyle in different positions or reference a jaw position (centric relation) that isn’t itself the defining anterior limit of movement.
