Class III treatment with invisalign in nongrowing patients without extractions

Adriana Vivar Hernandez

Class III malocclusions can be skeletal or dental. In a Class III skeletal discrepancy, the maxilla can be retro gnathic, the mandible can be prognatic, or both conditions may be present. In these patients, the ANB angle is decreased at 0 degrees or less, and the Wits analysis is negative. In non-growing patients with dental class III malocclusion or very mild skeletal discrepancy, non-extraction treatment may be attempted with clear aligners with mandibular interproximal reduction (IPR) in conjunction with class II elastic wear and mandibular molar distalization.
