which occlusal forces are of least concern? Why? Which forces/loading should be avoided? Why

Solution

Occlusal forces within the normal range are adapted by the tissues but the forces exceeding the normal range or the adaptive capacity of the tissues lead to trauma. The forces are divided based on the direction, duration, magnitude and frequency of application. These forces are normal physiological forces, impact forces, contineus forces and jiggling forces. The normal physiological forces are of least concern because they are produced during chewing and swallowing and their pressure is less and donot exceed 5N. They are needed for maintainence of healthy and functional bone.

Jiggling forces should be avioded because they are deletrious and result in widening of alveolus and increased motility.
