Abstract
Objective: The purpose of this study was to compare long-term stability and satisfaction between orthodontic camouflage and orthognathic surgery in treatment 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 bimaxillary 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 surgery 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 because of potential surgical complications or financial difficulties, camouflage treatment may be an effective alternative treatment.
Highlights
Class III malocclusion [1,2,3,4,5] is a structural deviation in the sagittal relationship between the maxillary and mandibular bony arches
The results suggest that both camouflage and surgical treatment in moderate skeletal Class III adults can achieve satisfactory outcomes and provide long-term stability
When treating non-growing patients with skeletal Class III malocclusion, only the two following treatment alternatives are possible [2]: 1) orthodontic repositioning of the teeth to camouflage the underlying skeletal discrepancy or 2) orthognathic surgery combined with orthodontic treatment
Summary
The sagittal relationship between the maxillary and mandibular bony arches. It is characterized by maxillary retrusion, mandibular protrusion, or a combination of the two. Many case reports have discussed Class III malocclusion treated with orthodontic camouflage [3,4,5] with satisfactory results, there has been almost no discussion of long-term stability (>3 years). Costa [6] reported on the use of orthodontic camouflage in patients with skeletal Class III malocclusion and found relapses over the eighteen months after the end of active treatment. For patients with Class II malocclusion, according to Mihalik [11], long-term stability appeared to be the same for patients treated with camouflage treatment or combined treatment. The author noted that patients treated with orthodontic camouflage displayed fewer severe problems than those treated surgically These data are insufficient to report outcomes of alternative treatments for comparable problems. The aim of the present study was to compare longterm stability and satisfaction between patients receiving orthodontic camouflage and orthognathic surgery
