Introduction: Skeletal Class III malocclusion is clinically presented as a result of maxillary retrusion, mandibular protrusion, or a combination of the two. It is often associated with complex dento-alveolar problems, which include an anterior edge-to-edge relation or anterior and posterior crossbite (Mousoulea dkk., 2016). Patients with Class III malocclusion exhibit potential aesthetic problems presenting a concave profile and a vertical function pattern which limits their function to vertical movements. The prevalence of Class III malocclusion presents a wide variety among and within populations, declared high around Asian populations, with a 23% rate. Case Report: A girl 14-year old with Skeletal Class III with anterior crossbite, unilateral posterior crossbite, and concave profile. Conclusion: The patient’s overall treatment resolved the patient’s chief complaint, correcting maxillary crowding, and anterior crossbite, achieving Class I Molar and Canine Relationship, a harmonious facial profile, and positive overjet achieved.
