Description
Intermaxillary traction is a dental orthopedic procedure used to correct jaw alignment issues like severe malocclusion or post-surgical stabilization, typically costing ¥200–500 in China; ChinaMedicalHub helps coordinate hospital appointments and interpreter support.
Main Uses
Primary clinical uses include correcting Class II and Class III malocclusions by modifying jaw relationships; facilitating presurgical decompensation in orthognathic cases; stabilizing temporary occlusion during multi-phase orthodontic treatment; managing mandibular asymmetry or functional shifts; and supporting post-surgical orthopedic adaptation. Applicable scenarios encompass adolescent growth modification, adult camouflage orthodontics, and adjunctive therapy before/after orthognathic surgery.
Normal Range
Not applicable —颌间牵引治疗 (Intermaxillary Traction Therapy) is a clinical orthodontic/orthognathic treatment modality, not a diagnostic laboratory test with numerical biomarkers or quantifiable 'values'. It involves applying controlled mechanical force between the maxilla and mandible using elastics, springs, or appliances to correct dental and skeletal discrepancies. There is no standardized 'normal range' of numerical values; instead, clinical parameters include prescribed force magnitude (typically 100–500 g per side), wear time (e.g., 12–24 hours/day), duration (weeks to months), and monitored outcomes such as occlusal improvement, cephalometric angular changes (e.g., ANB reduction ≥2°), and stable intercanine/intermolar width adjustments.
Low Values - Possible Causes
Inadequate patient compliance (insufficient wear time), use of undersized or degraded elastics/springs, premature appliance detachment or breakage, insufficient anchorage (e.g., poor bracket bonding or loose bands), and underestimation of required force during treatment planning.
High Values - Possible Causes
Excessive elastic strength or spring activation beyond prescribed limits, prolonged continuous wear without rest periods leading to tissue overload, improper appliance design causing unbalanced force vectors, patient self-adjustment (e.g., adding extra elastics), and concurrent orthodontic mechanics amplifying net intermaxillary force.
