Correction of Class II malocclusion and soft tissue profile in an adult patient

Abstract

Treatment of Class II malocclusion in nongrowing individuals is a challenging situation for the clinician. Class II malocclusion with bialveolar protrusion often dictates premolar extractions with maximum anchorage. The present article describes the case of an adult female with skeletal Class II malocclusion, bimaxillary protrusion, increased overjet, deep bite, lip protrusion, everted lower lip, deep mentolabial sulcus, and lip incompetence. To correct the malocclusion, all four first premolars were extracted. Direct anchorage from miniscrews was used for retraction of the anterior segment. The mandibular buccal segment was protracted into the extraction space using Class II mechanics. Ideal Class I canine and molar relation were achieved in 24 months. There was a significant improvement in facial profile and smile esthetics of the patient.

The Importance of the Occlusal Plane in Predicting Better Facial Soft Tissue in Class II Malocclusion in Ethnic Javanese

“…Many factors need to be considered when treating adult patients, such as aesthetics, skeletal vertical dimensions, dentoalveolar protrusion, lip formation, facial convexity, and occlusion stability. 8,9 Characteristics of Class II malocclusion include the protrusion of the upper jaw and upper lip, incompetent lip growth, poor chin morphology, and small nasolabial angles, which are often the main complaint of patients. [10][11][12] Measurements in this study were divided into three parts: occlusal plane (OCC-SN, OCC-FH, and OCC-MP), facial balance and soft tissue profile (FMA, FMIA, IMPA, and Z-angle), and vertical plane of the face (Y-axis and facial axis) as support.…”
