area
3. Medial pterygoid muscle may influence the denture border in the region of the
pterygomaxillary notch
4. None of the above
Prosthodontics
Answer: 3
Explanation: The medial pterygoid muscle primarily functions to move the
mandible medially and assist in closing the jaw. It does not directly influence
the borders of a maxillary denture in the region of the pterygomaxillary notch.
Instead, it is involved in the movement of the mandible and may indirectly
affect the fit and stability of the denture.
