This lecture will present a review of the rationales, indications, methods, and effects of orthodontic treatment with second molar extractions in open bite cases. The second molar extraction may be a viable strategy in selected open-bite cases to remove ‘wedges’ and to drive first molars distally. But it is important to understand the indications and limitations of this treatment choice. The following topics will be explained with cases: 1. Effects of second molar extraction, 2. Indications and contradictions of second molar extraction, 3. Timing of extraction, 4. Limitations in second molar extraction, and 5. Cases.
Define the indications of second molar extraction to treat open bite cases.
Analyze the limitations of second molar extraction to treat open bite cases.
