Non-Surgical Treatment of Class II Division 1 Malocclusion in an Adult Patient with a Missing Lower Lateral Incisor Tooth: A Case Report

Abstract

Class II Division 1 malocclusion is clinically more widespread than any other form of malocclusion and can be managed in a variety of ways, taking into account variables such as patient compliance, age, and anteroposterior disparity. Orthodontic camouflage treatment, aimed at masking the underlying skeletal discrepancy, is an acceptable option for most patients. This typically involves the extraction of two maxillary premolars in cases without mandibular arch crowding, or the extraction of two maxillary and two mandibular premolar teeth when crowding is present. The present case report aimed to discuss the successful treatment of a unique case involving a 19-year-old adult female patient with Class II Division 1 malocclusion, a missing mandibular left lateral incisor, and an overjet of 7 mm. Since the patient declined surgical and prosthetic treatment, an alternative, novel, and unorthodox method of camouflage treatment was employed, which involved the extraction of maxillary first premolars combined with symmetrical incisor space closure. The achieved treatment outcomes included a functionally and aesthetically acceptable occlusion, reduced overjet, and an improved soft tissue profile.
