Abstract
This article presents the nonsurgical orthodontic treatment of a skeletal Class III malocclusion of an adult patient.
Highlights
A Class III malocclusion invariably shows skeletal and dentoalveolar components
A Class III phenotype is commonly associated with craniofacial characteristics displaying a sharp cranial base angle, a retrusive maxilla, and a protrusive mandible
Dentoalveolar compensations are frequently observed in Class III patients and, in addition to maintaining function, the compensations mask the underlying skeletal discrepancy
Summary
A Class III malocclusion invariably shows skeletal and dentoalveolar components. Genetic and environ mental factors act as positive stimuli regulating mandibular growth, related to mandibular functional anterior deviation or mouth breathing.[1,2,3,4] A Class III phenotype is commonly associated with craniofacial characteristics displaying a sharp cranial base angle, a retrusive maxilla, and a protrusive mandible. Subjects with a retrusive maxilla are more likely to present with a hyperdivergent facial pattern, demonstrating vertical growth as a potential compensation mechanism.[1] Dentoalveolar compensations are frequently observed in Class III patients and, in addition to maintaining function, the compensations mask the underlying skeletal discrepancy. The aim of the present article is to discuss an orthodontic treatment approach using miniscrews for anchorage, in an adult skeletal Class III malocclusion, who refused an orthognathic surgical procedure
