Long-Term Follow-Up of Class II Adults Treated with Orthodontic Camouflage: A Comparison with Orthognathic Surgery Outcomes

摘要

Thirty-one adults who had been treated with orthodontics alone for Class II malocclusion were recalled at >5 years post-treatment, for evaluation of cephalometric and occlusal stability and satisfaction with treatment outcomes. These were compared to similar data for long-term outcomes in patients who had surgical correction. Small mean changes in skeletal landmark positions did occur long-term, but were in general much smaller than in the surgery patients. The percentage of patients with a long-term increase in overbite was almost identical in the orthodontic and surgery groups, but Class II surgery patients (who had more severe problems initially) were nearly twice as likely to have an increase in overjet long-term. The patients' perceptions of outcomes were highly positive in both the orthodontic and surgical groups. The camouflage patients reported fewer functional or TM joint problems than the surgery patients, and had similar reports of overall satisfaction with treatment.
