Encombrement dentaire（ED） - Guide de tourisme médical et soins en Chine

Dental crowding refers to teeth overlapping, rotated, or displaced due to insufficient arch space. Treatment aims to align teeth and restore function—guided by age, severity (measured via Little’s Irregularity Index or Bolton analysis), skeletal pattern, and patient goals. Mild cases in adolescents may resolve with observation or space management. Moderate-to-severe crowding usually requires active intervention. Adults often need comprehensive planning including periodontal and occlusal assessment before proceeding.

Non-surgical options Clear aligners (e.g., Spark, Invisalign-compatible protocols) are common for mild-to-moderate crowding in patients aged 12–35. Requires full-arch impressions, CBCT, and digital setup. Estimated cost: USD 1,800–3,200 for full treatment (24–36 months). Traditional metal braces (Damon Q2 or similar self-ligating systems) start at USD 1,400–2,600. Includes initial consultation, bracket bonding, 8–12 adjustment visits, and retention. Removable appliances (Hawley retainers, Schwarz expanders) apply only to select pre-adolescent cases with transverse deficiency—USD 350–700. All prices exclude pre-treatment imaging.

Surgical/procedural options Extraction-based fixed orthodontics remains standard for severe crowding (>6 mm space deficiency). Common extractions: first premolars (bilateral). Per-hospital protocol includes panoramic X-ray, lateral cephalogram, model analysis, and surgical clearance. Total estimated cost: USD 2,100–4,500. Orthognathic surgery (e.g., mandibular setback + maxillary expansion) is reserved for adult skeletal Class III or bimaxillary discrepancies with crowding. Requires collaboration between Oral & Maxillofacial Surgery and Orthodontics departments at hospitals like Peking University School of Stomatology or Shanghai Ninth People’s Hospital. Preoperative workup adds USD 320–580. Full surgical-orthodontic course: USD 8,900–14,300.

Complex/resistant cases Patients with cleft-related crowding, severe hypodontia, or post-trauma arch collapse may require micro-implant anchorage, corticotomy-assisted alignment, or staged prosthodontic-orthodontic integration. These involve multidisciplinary review at specialized centers (e.g., West China Hospital Department of Oral and Maxillofacial Surgery). Costs range USD 5,200–11,600 depending on implant count, bone grafting needs, and lab-fabricated appliances.

Quick selection guide Under 14? Prioritize growth monitoring + removable expansion if indicated. Budget under USD 2,000? Metal braces or basic aligner plans. Severe crowding + jaw imbalance? Surgical-orthodontic pathway likely. Comorbidities like uncontrolled periodontitis or diabetes require stabilization first.
