Abstract

Introduction: Class III malocclusion has a multifactorial etiology, resulting from interactions among innate, genetic, and environmental factors. It is generally characterized by a concave facial profile, anterior crossbite, increased effective mandibular length, and, in combined cases, midface deficiency due to maxillary retrusion. Objective: This case report aims to review the biological basis and characteristics of Class III malocclusion in the mixed dentition, as well as its early functional orthopedic management. Case Report:An 8-year-old girl with anterior crossbite and skeletal Class III malocclusion was treated with the Klammt Class III elastic open activator, resulting in correction of the anterior crossbite and a favorable change in her facial profile. Conclusion: The Klammt Class III elastic open activator produces favorable outcomes in anterior crossbite correction, enhances facial profile and posture, and redirects maxillary and mandibular growth during the mixed dentition stage.
