2015 AAO Annual Session - Mechanical Strategies to Improve Open Bite Treatment Stability / Surgical Correction of Anterior Open Bite With Mandibular Counterclockwise Rotation

Mechanical Strategies to Improve Open Bite Treatment Stability

This presentation will describe the treatment approaches of open bite in the different maturational stages, their respective expected clinical stability and the mechanical strategies that can be used to increase stability in the long-term.

Learning Objectives:

• Distinguish the clinical stability of different approaches of open bite treatment
• Perform mechanical procedures to increase open bite treatment stability

Surgical Correction of Anterior Open Bite With Mandibular Counterclockwise Rotation

Historically, open bite closure through surgical counterclockwise rotation of the mandible and intermaxillary wire fixation was discontinued due to the high degree of instability associated with this technique. Instead, correction of open bite deformities with maxillary surgical impaction became the standard of care. Currently, the development of rigid internal fixation has allowed clinicians to again close anterior open bite discrepancies in the mandible with bilateral split osteotomies and counterclockwise rotation of the distal segment.

Learning Objectives:

• Manage presurgical orthodontic preparation for cases being prepared for open bite correction in the mandible
• Evaluate the long-term stability of surgical open bite correction through counterclockwise mandibular rotation
