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.
Alveolar arch forms are generally classified into three primary shapes based on their curvature and width-to-length ratio: alveolar arch
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 bone thickness varies significantly by arch form
Narrow anterior that widens toward the posterior. It provides moderate resistance to movement. alveolar arch
