Mandibular Molar Distalization Using Interradicular Microimplants and Direct Anchorage: A Case Report

Management of skeletal Class III malocclusion using traditional orthodontic mechanics can be challenging because of limited anchorage control and undesirable reciprocal effects. However, the introduction of microimplants allowed a better control of tooth movement, reducing the need for surgical intervention in selected cases. This case report illustrates the effectiveness of direct skeletal anchorage using interradicular microimplants for mandibular molar distalization in the treatment of a skeletal Class III malocclusion. A female patient aged 19 years showing a mandibular prognathism and a normodivergent growth pattern underwent mandibular dentition distalization using a direct anchorage protocol supported by interradicular microimplants. A distalization of the mandibular dentition and a controlled vertical dimension were achieved. The mandibular plane rotated in a counterclockwise pattern, allowing the closure of the anterior bite while maintaining proper inclination of the lower incisors and stable alveolar bone support. Direct anchorage using interradicular microimplants represents an effective non-surgical strategy for camouflage treatment in selected skeletal Class III cases.
