Study Title: Evaluation of Treatment Outcomes of Interceptive Orthodontic Intervention for Class III Malocclusion Using Inclined Plane Appliance Combined With Variable Bracket Placement Objective: To evaluate the clinical and radiographic outcomes of interceptive orthodontic treatment for skeletal Class III malocclusion in children Participants: Children aged 7 to 12 years diagnosed with skeletal Class III malocclusion (ANB < 0°, Wits < -2mm) and cervical vertebral maturation stages CS1, CS2, or CS3, treated at the Ho Chi Minh City Hospital of Odonto-Stomatology from 2025 to 2026 Methodology: This is a descriptive study with a non-controlled clinical intervention The treatment involves the application of a fixed inclined plane appliance on the mandibular teeth combined with variable bracket placement (bonded at a 180-degree rotation) on the maxillary anterior teeth to promote the forward movement of the upper incisors and stimulate maxillary alveolar bone growth Evaluation: Treatment efficacy is assessed after 6 months by comparing skeletal, dental, and soft tissue changes using standardized lateral cephalometric radiographs and Cone Beam Computed Tomography (CBCT) Success is defined by achieving a positive overjet (≥2mm), overbite (≥2mm), and an Angle Class I molar relationship

| Treatment success of interceptive orthodontic intervention for skeletal Class III malocclusion | Evaluation of treatment success based on clinical and radiographic criteria. Success is defined as achieving: Positive overjet (OJ ≥ 2mm) . Positive overbite (OB ≥ 2mm) . Angle Class I molar relationship . The assessment includes measuring changes in skeletal, dental, and soft tissue parameters using standardized lateral cephalometric radiographs and Cone Beam Computed Tomography (CBCT) | 6 months after the start of the intervention |
