Question

What are border movement and neutral zone while recording muscles?

• A. Border movement refers to the movement of the mandible, and neutral zone refers to the position where muscles have equal force.
• B. Border movement refers to the limits of tooth movement, and neutral zone refers to the natural resting position.
• C. Border movement refers to the position of teeth during occlusion, and neutral zone refers to the area of the tongue's influence.
• D. Border movement refers to the jaw's occlusal position, and neutral zone refers to the teeth's contact.

Hint:

When recording muscle positions for dentures, focus on the balance between opposing muscle forces in the neutral zone to ensure comfort and function.

Answer 1

The Correct Option is A

Border movement refers to the range of movement of the mandible during chewing or speech, while the neutral zone is the region in the oral cavity where the forces of the lips and cheeks balance the forces of the tongue. This is important for recording accurate muscle positions when constructing prostheses or dentures.
