Alveolar — Arch
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.
Narrow anterior that widens toward the posterior. It provides moderate resistance to movement. alveolar arch
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. Right and left sides run almost parallel with
Success in dental implants depends on the quality and volume of the alveolar bone. Excessive resorption or thin bone levels can lead to complications like fenestration or implant failure. 3. Remodeling and Preservation It provides moderate resistance to 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
