Skeletal Class III malocclusion correction using miniscrew implants

Abstract

This article describes the orthodontic treatment of a young adult with a skeletal Class III malocclusion. The treatment consisted of mandibular molar distalization using miniscrew implants (MSIs). MSIs were placed between the mandibular second premolars and mandibular first molars. Mandibular molars were distalized using open nickel-titanium coil springs, and indirect anchorage was provided by the MSIs. The lower anterior segment was distalized with direct anchorage using closed nickel-titanium coil springs and the same MSIs. The active treatment period was 28 months (it took 4 months to distalize the lower molars). Normal occlusion was obtained and facial balance was improved.
