The management of congenitally Missing Bilateral Maxillary Lateral Incisors (MBMLI) remains one of the most intriguing and challenging multidisciplinary paradigms in contemporary orthodontics.
Because lateral incisors play a vital role in establishing anterior guidance, arch symmetry, and overall facial esthetics, their absence requires precise diagnostic planning.
Clinicians are routinely faced with the strategic dilemma of either opening space for implant-supported or prosthetic restorations, or closing space via canine substitution and subsequent anterior recontouring.
Achieving a harmonious, natural-looking smile in MBMLI cases extends far beyond mere space management; it hinges on controlling the mesiodistal axial angulations (crown-root tipping) of the adjacent anterior teeth.
The axial inclination of maxillary central incisors and canines directly dictates light reflection, soft tissue emergence profiles, and root alignment within the alveolar bone.

However, standard compensatory tooth movements can inadvertently alter these critical angulations, potentially compromising long-term esthetic stability and periodontal health if left unmonitored.
This clinical research study provides a comprehensive comparative evaluation of the mesiodistal axial angulations of maxillary central incisors and canines in patients undergoing orthodontic treatment for MBMLI.
By analyzing panoramic radiographic data across space-opening protocols, space-closure mechanics, and untreated ideal controls, the study investigates how different therapeutic approaches impact root parallelism and incisor positioning pre- and post-treatment.
Understanding these specific angulation changes provides orthodontists and restorative dentists with invaluable, evidence-based insights.
By highlighting the biomechanical tendencies of central incisors and canines during space closure versus space opening, this study helps clinicians optimize bracket placement, refine torque expression, and select the most predictable, esthetically pleasing, and cost-effective treatment strategy for patients with missing lateral incisors.
