Orthodontic camouflage versus orthognathic surgery - PDF

Objective: The purpose of this study was to compare long-term stability and satisfaction between ortho- dontic camouflage and orthognathic surgery in treat- ment of moderate skeletal Class III adults. Materials and Methods: A total of 25 adults females who had been treated with orthodontic camouflage for Class III malocclusions were recalled at least 3 years post- treatment to evaluate stability and satisfaction with treatment outcomes. The data were compared with similar data for long-term outcomes in 21 patients with the same Class III problems who had bimaxil- lary surgical correction. Results: In the camouflage patients, small mean changes in skeletal landmark positions occurred over the long term, although the changes were generally much smaller than in the surgery patients. Dental changes in the surgery group were more severe than those in the camouflage group. The camouflage patients reported fewer functional or temporomandibular joint problems than did the sur- gery patients. Both groups reported similar levels of overall satisfaction with treatment. Conclusion: The results suggest that both camouflage and surgical treatment in moderate skeletal Class III adults can achieve satisfactory outcomes and provide long-term stability. If patients do not readily accept surgery be- cause of potential surgical complications or financial difficulties, camouflage treatment may be an effective alternative treatment.

Class III malocclusion [1-5] is a structural deviation in the sagittal relationship between the maxillary and man- dibular bony arches. It is characterized by maxillary re- trusion, mandibular protrusion, or a combination of the two. The condition is sometimes associated with anterior crossbite and increased or decreased divergence. Studies indicate that 63% - 73% of Class III malocclusion cases are of a skeletal type [3]. Prevalence varies by race [1], with a higher prevalence found in Asian populations (ranging from 15% - 23%) and a lower prevalence re- ported (below 5%) for American, European, and African Caucasian populations...
