Alveolar Arch [FAST]

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.

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 alveolar arch

Narrow anterior that widens toward the posterior. It provides moderate resistance to movement. Right and left sides run almost parallel with

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 Excessive resorption or thin bone levels can lead

The shape and size of the arch directly impact complete denture retention . Square arches are typically preferred as they provide greater surface contact for adhesive and cohesive forces.

Alveolar arch forms are generally classified into three primary shapes based on their curvature and width-to-length ratio:
