Expert consensus sets new framework for adult orthodontic care

International experts have published three consensus articles in the International Journal of Oral Science to guide adult orthodontic care for patients with bone defects, periodontal concerns, and complex skeletal discrepancies. The framework aims to improve diagnosis, treatment planning, and safer tooth movement as more adults seek orthodontic treatment.

Why it matters: - Adult orthodontic care is becoming more complex as more adults seek treatment with reduced bone support, periodontal concerns, and skeletal discrepancies. - The new consensus framework is designed to help orthodontists deliver safer, more predictable, and more personalized treatment. - The recommendations may lower the risk of periodontal complications while expanding treatment options for appropriately selected patients.

What happened: - International experts published three consensus articles in the International Journal of Oral Science. - The articles cover orthodontic-associated alveolar ridge augmentation for adult patients, clinical strategies for clear aligner treatment, and orthodontic treatment of protrusive facial deformities. - The papers were published on March 25, 2026; March 13, 2025; and February 1, 2025. - Dr. Li Xu said the growing demand for adult orthodontic treatment has highlighted critical challenges.

The details: - The guidance is built on systematic evidence reviews and multidisciplinary expert consensus. - The framework recommends diagnosing protrusive facial deformities through total-element diagnosis, which evaluates the patient as a whole rather than focusing only on the teeth. - The approach calls for assessing sagittal, vertical, and transverse relationships, growth potential, and other clinical factors to identify the causes of the deformity and set realistic goals. - Facial, skeletal, dental, functional, and periodontal assessments should all shape treatment objectives before a treatment approach is chosen. - Dr. Chenchen Zhou said diagnosis of protrusive facial deformities should follow the principle of total-element diagnosis. - Clear aligner planning should use complete and accurate patient data, including facial and intraoral photographs, radiographic examinations, cone beam computed tomography scans, and digital dental models. - The consensus says initial, intermediate, and final tooth positions are the three keys to successful clear aligner therapy. - Treatment planning should map every stage before active treatment begins and should match case complexity and biomechanical demands. - Dr. Wenli Lai said precise initial tooth position requires complete and accurate patient data. - Adult patients often have reduced alveolar bone support or pre-existing defects that increase periodontal risk during orthodontic treatment. - CBCT imaging for comprehensive assessment of alveolar bone is strongly recommended, especially when extensive tooth movement is expected. - The guidance includes orthodontic-associated alveolar ridge augmentation as an evidence-based strategy when additional bone support is needed.

Between the lines: - The consensus reflects a shift from tooth-focused orthodontics to whole-patient planning that combines facial aesthetics, skeletal relationships, and tissue health. - Digital tools matter, but the articles frame them as support for, not substitutes for, clinical judgment. - The emphasis on biology suggests adult orthodontics is moving toward more conservative movement planning when tissue limits raise complication risk.

What's next: - The authors say the recommendations will evolve as new evidence emerges. - Future large-scale clinical studies, technological advances, and multidisciplinary research are expected to refine the guidance. - Dr. Chenchen Zhou said continued research and better methods should improve treatment outcomes and long-term patient stability. - The three papers are available in the International Journal of Oral Science: the alveolar ridge augmentation consensus, the clear aligner strategies consensus, and the protrusive facial deformities consensus.
