Skeletal Class Iii Malocclusion Correction Via Surgery Early Approach

This case report illustrates the successful implementation of the Surgery Early Approach (SEA) in correcting a skeletal Class III malocclusion, demonstrating enhanced treatment efficiency through reasonable treatment protocols. A 23-year-old male presented with skeletal Class III malocclusion, characterized by mandibular prognathism and compensatory incisor inclinations. The protocol comprised 3 key phases: 1) Four-month presurgical orthodontic preparation focusing on posterior occlusion coordination, 2) Surgical intervention involving intraoperative extractions of #14/24 and segmental Le Fort I osteotomy with 3D maxillary repositioning, 3) Final occlusal refinement. Total treatment duration was 12 months, resulting in improved profile, stable occlusion, and harmonious root-bone relationships. The SEA concept emphasizes early surgical intervention to minimize long-term aesthetic compromise in presurgical orthodontics and reduce total treatment time. Strategic surgical design served as a key factor in this case, which mainly involved intraoperative extractions and segmental osteotomies. Firstly, this mode eliminated the need to close extraction spaces, significantly shortening the preoperative orthodontic period. Additionally, presurgical orthodontics prioritized root-bone harmony, avoiding excessive incisor decompensation to mitigate periodontal risks. Furthermore, digital technology increased the precision of surgery. More importantly, the 3D repositioning of bone fragments not only corrected incisor compensatory, but also optimized posterior occlusion. Generally, this case highlights SEA's efficacy in skeletal Class III management through strategic osteotomy design. The protocol achieved significant functional and aesthetic improvements within 12 months, demonstrating its potential as a time-efficient alternative for similar cases.
