  • Title: [Stability of orthodontic treatment of occlusal asymmetry].
    Author: Burstone C, Filleul MP, Pigeot V.
    Journal: Orthod Fr; 2000 Sep; 71(3):197-205. PubMed ID: 11039272.
    Abstract:
    A common finding in orthodontic patients is asymmetric occlusion. These asymmetries can be dental, skeletal, or functional in origin. Since many patients have typical posterior overjet the use of Class II-Class III and anterior crisscross elastics are contra-indicated. Even in skeletal discrepancies axial inclination compensation can produce relatively normal overjet in the arch. The best strategy for non-extraction therapy is to move teeth around the arch rather than an en-masse movement of the entire arch. A number of methods for unilateral distalization are discussed. Midline correction requires the determination of facial, apical base, and posterior midpoints. Differential mechanics between patients with apical base discrepancies and no apical base is presented. Although intermaxillary elastics can be indicated the undesirable effects of eruption and frontal occlusal plane tilt should be considered. Advantages in control and ease of occlusal correction rest with intra-arch mechanics. The use of intermaxillary elastics for the correction subdivision cases can lead to instability and or mandibular shifts.
