ProsthodonticsExplanation: In bilateral balanced occlusion, if the incisal
guidance is steep, it is necessary to create a compensating curve that is also
steep to maintain balanced occlusion during lateral movements. This helps to
ensure that the occlusal contacts remain balanced and stable, preventing tipping
or dislodgment of the denture during function. The other options do not
adequately address the need for balance in occlusion.

ProsthodonticsExplanation: The medial pterygoid muscle primarily functions to move the
mandible medially and assist in closing the jaw. It does not directly influence

Instead, it is involved in the movement of the mandible and may indirectly
affect the fit and stability of the denture.
