Narrow anterior that widens toward the posterior. It provides moderate resistance to movement.
Right and left sides run almost parallel with a broad anterior. This form offers the largest denture-bearing area and best resistance to rotational movement.
Alveolar bone thickness varies significantly by arch form. Studies indicate that square arches generally have thicker bone than tapered or ovoid forms, which can dictate the safe limits for orthodontic tooth movement.
A rounded, circular shape throughout. This form provides the least resistance to rotational forces and is often associated with the smallest denture-bearing surface. 2. Clinical Significance
