Description
Orthodontic treatment performed before and/or after orthognathic surgery to align teeth properly with the repositioned jaws, ensuring optimal occlusion and facial aesthetics.
Main Uses
Primary purpose is to finalize dental occlusion, aesthetics, and functional stability after orthognathic surgery. Key applications include: refining incisor inclination and torque, correcting residual dental crowding or spacing, establishing ideal overjet/overbite and interarch relationships, eliminating occlusal interferences, coordinating dental midlines, and stabilizing the occlusion prior to retainer phase. It is indicated for patients who underwent bimaxillary or single-jaw osteotomies (e.g., Le Fort I, SSRO, genioplasty) and require fine-tuning of dental position to achieve optimal function, phonetics, and facial harmony.
Normal Range
Not applicable — 'Orthognathic Surgery Postoperative Orthodontics' is not a laboratory or quantitative diagnostic test with numerical values; it is a clinical treatment phase involving dental alignment and occlusal refinement following jaw surgery. There are no standardized numeric reference ranges (e.g., no units like mmol/L or mm). Success is assessed qualitatively and semi-quantitatively via clinical parameters: overjet (2–4 mm), overbite (1–3 mm), intercanine/intermolar widths (sex- and age-adjusted norms), dental midline coincidence (<1 mm deviation), and stable occlusion (Class I canine/molar relationship, absence of posterior open bite, minimal tooth mobility). Cephalometric norms (e.g., ANB 2°±2°, SNB 79°±2°) serve as surgical-orthodontic benchmarks but vary by population and protocol.
Low Values - Possible Causes
Low values are not defined for this procedure; however, suboptimal outcomes (e.g., reduced overjet <2 mm, excessive overbite >4 mm, or midline discrepancy >1.5 mm) may result from: 1) Inadequate pre-surgical orthodontic decompensation, 2) Surgical undercorrection or condylar resorption, 3) Poor postoperative orthodontic torque control or anchorage loss, 4) Noncompliance with elastics or retainers, 5) Unrecognized temporomandibular joint dysfunction affecting occlusal settling.
High Values - Possible Causes
High values are not defined for this procedure; however, excessive measurements (e.g., overjet >5 mm, overbite >5 mm, or intercanine width >3 mm beyond normative range) may stem from: 1) Surgical overcorrection (e.g., excessive maxillary advancement or mandibular setback), 2) Orthodontic overshooting during active alignment (e.g., excessive proclination), 3) Relapse due to insufficient retention or soft-tissue pressure, 4) Late mandibular growth in adolescents, 5) Unplanned dental extractions or arch expansion without skeletal coordination.
