CASE REPORT

Non-surgical Treatment of a Late Adolescent Patient with Skeletal Class II Malocclusion Using Clear Aligners: A Case Report

The Open Dentistry Journal 24 Nov 2022 CASE REPORT DOI: 10.2174/18742106-v16-e2206276

Abstract

Background/Introduction:

There are a variety of treatment modalities for orthodontic treatment of patients with skeletal Class II malocclusions in late adolescence. These treatment modalities may include surgical intervention, camouflage treatment, functional appliances, extraction of teeth, and/or Class II elastics mechanics. Most Class II mechanics produce retroclination of the upper incisors and proclination of lower incisors. These dentoalveolar effects limit the possibility for forward mandibular projection/growth, hence minimizing skeletal improvement.

Case Presentation:

To present a unique case report that was treated with a new perspective in maximizing skeletal improvement in a late adolescent male with skeletal Class II malocclusion and deep overbite.

A 15-year-old male presented with a skeletal Class II pattern due to mandibular retrognathism was treated with non-extraction, non-surgical technique using clear aligners in two phases. Phase 1 was designed to decompensate the compensated inclination of his anterior teeth, and phase II was planned to correct his skeletal and dental Class II malocclusion/mal relation. Results: Maxillary incisors decompensation of the inclination of the upper and lower incisors and posterior teeth intrusion allowed forward mandibular projection that led to skeletal and dental correction of his malocclusion and improvement of his chin forward projection.

Conclusion:

This case report shows successful treatment of a Class II malocclusion in alate adolescent male. This method could perhaps be used for similar cases, avoiding the need to extract teeth or include surgical intervention.
