The treatment of midline discrepancy is one of the most challenging problems among orthodontists. The treatment planning and choosing correct biomechanics for the patient with midline discrepancy needs differentiation between dental and skeletal origin. Cephalometrics, PA head film, study model, intra oral and facial photograph, and clinical examination gives the clue of the nature of the midline discrepancy. Among those databases, the role of axial inclination of the dentition gives one of the most important keys for the correct diagnosis and treatment planning. Correcting the axial inclination can be helpful for midline correction, and sometimes axial inclination should be sacrificed for masking underlying skeletal origin problems.
Learning Objectives:
After this session, attendees will be able to:
Identify the origin of midline discrepancies whether they are from facial, apical or geometric midline.
Assess the limits of orthodontic tooth movement and make decisions on whether to employ surgery.
Select appropriate biomechanics that facilitate the most efficient approaches while minimizing potential side effects.
