Abstract: Bimaxillary protrusion, a prevalent dentofacial deformity, is characterized by excessive lip protrusion in the lateral profile. It originates from either dental causes (proclined incisors) or skeletal factors (jaw abnormalities). The standard treatment involves premolar extractions followed by anterior retraction. However, this approach carries risks of alveolar bone loss and root resorption, which vary according to force magnitude/duration and individual patient factors. This review examines the critical determinants of these complications during retraction and provides evidence-based clinical recommendations.

Key words: bimaxillary protrusion, alveolar bone remodeling, root resorption
