The range of motion, as measured in millimeters, is least for the
1. pure hinge like opening and closing movement
2. protrusive movement
3. left lateral movement
4. Bennet movement
Prosthodontics
Answer: 4
Explanation:
Pure hinge-like opening and closing movement: The range of pure rotation in
the temporomandibular joint (TMJ) was determined to be up to 15–20 mm in the
1960s. However, recent research suggests that pure rotational movement may not
occur.
Protrusive movement: The normal range of motion for protrusive movement is
8–12 mm.
Left lateral movement: The normal range of motion for left lateral movement
is 8–12 mm. The normal range of motion for mouth opening is 35–60 mm.
The average immediate Bennett shift was found to be 1.05 mm on the left
side and 1.12 mm on the right side when firm guidance was used.
