Orthodontic Treatment for Borderline Class III Malocclusion in Adults: Nonextraction Treatment with Anterior Bite Turbo: A Case Report

Abstract

Retrusive upper lips, retroclined upper incisors, a shorter midface, and a larger maxillary-mandibular difference are the characteristics of borderline Class III malocclusion. Individuals with borderline Class III malocclusion frequently exhibit certain morphologic, dental, and skeletal traits, which should aid in the diagnosis of the condition. To report the case of a 22-year-old Vietnamese woman who complained of having tense front teeth and lacking confidence when smiling. Medical history did not find anything strange, there was root canal treatment of the first premolar on the left of the upper jaw, asymmetrical concave chin, and right deviation. Orthodontic camouflage treatment using anterior bite turbos in combination with early light short Class III elastics and box elastics was proposed since the patient declined to have orthognathic surgery. In just 10 months of treatment, a Class I molar and canine relationship was created, an anterior crossbite was corrected via mandibular retraction, and severe skeletal malocclusions were successfully treated without orthognathic surgery. Smiling currently showcases the patient's maxillary incisors more prominently, and her lower lip fullness has diminished, giving her a more attractive smile and a significant improvement to her facial profile.

Anterior bite turbo (flowable resin) was bonded on the LR2, LR1, and LL1 to open the bite. Early light short triangle Class III elastics (Quail, 3/16-in, 2-oz; Ormco), box elastics (Fox, 1/4″, 3.5-oz; Ormco) from UR4, UR5 to LR5, and LR6 were used to correct the anterior crossbite
