Planned Incisor Positioning: Evidence Based Positioning Strategy

Planned incisor positioning is a cornerstone of orthodontic diagnosis and treatment planning, as it directly influences facial esthetics, occlusal function, stability, and periodontal health. Ideal positioning of the maxillary and mandibular incisors is determined through a comprehensive evaluation of skeletal pattern, dental relationships, soft-tissue profile, and functional requirements. Classical cephalometric analyses, including those proposed by Tweed, Steiner, and Holdaway, provide quantitative guidelines for incisor inclination and anteroposterior position relative to basal bone and facial profile. Andrews' Six Keys to Normal Occlusion emphasize correct axial inclination and alignment of incisors as prerequisites for optimal occlusion. Contemporary concepts integrate soft-tissue paradigms, recognizing that incisor position must be harmonized with lip posture, smile esthetics, and facial balance rather than relying solely on hard-tissue norms. Improper incisor positioning may compromise facial esthetics, predispose to relapse, and increase the risk of periodontal damage.
