Implants need to be how many mm from mental nerve?
2 mm
3 mm
4 mm
5 mm
The correct answer is: 5 mm
Implants need to be placed a minimum of 5 mm away from the mental nerve to avoid any potential damage to the nerve during placement. This distance helps to ensure the safety and health of the patient, as injuring the mental nerve can lead to numbness or altered sensation in the lower lip and chin area. Option A (2 mm), Option B (3 mm), and Option C (4 mm) are all less than the recommended 5 mm distance, making them incorrect choices for the optimal placement of implants in relation to the mental nerve.
