Abstract :
Objective: The aim of this study was to compare the stability of dentoskeletal parameters of Class II patients treated with either functional appliances or mandibular advancement surgery.
Materials and Methods: The study consisted of two groups: Group I - 10 growing patients treated with removable functional appliances and Group II - 10 non growing patients treated with surgical mandibular advancement. Dentoskeletal changes that occurred were compared on lateral cephalograms taken at three points of time: Pre treatment (T1), post treatment (T2) and long term post treatment (T3).
Results: Both functional appliances and surgical patients showed stable results over time. Small amount of relapse was observed in surgical patients from post surgical (T2) to long term post surgical (T3) which was statistically insignificant. Conclusion: Both functional appliances and mandibular advancement surgery can be used successfully for the correction of Class II malocclusion.
