2019 Annual Session Conference


Vertical Considerations in Class II Treatment


May 4, 2019 3:55pm ‐ May 4, 2019 4:25pm

Description

Vertical dimension of the maxillomandibular complex should be controlled along with horizontal and transverse correction to achieve a successful orthodontic treatment of Class II malocclusion. Vertical expansion of either the maxillary or mandibular posterior teeth causes many undesirable reactions. Consequently, good facial balance can be obtained by Tweed-Merrifield directional force technology with TAD, which provide horizontal and vertical anchorage control in the maxillary and mandibular posterior teeth, and intrusion and torque control in the maxillary anterior teeth, resulting in a favorable counterclockwise mandibular response, particularly in hyperdivergent Class II patients.

Learning Objectives:

  • Define and identify the factors influencing the vertical dimension in Class II malocclusion.
  • Understand the biomechanics for vertical control in Class II treatment using TAD.
  • Describe and explain the importance of the vertical control using new protocol of Tweed-Merrifield directional force technology in Class II treatment.
