Comparison of 1-year follow-up results of Forsus, headgear, and extraction treatment in Class II malocclusion

This cross-sectional case-control observational study aimed to use lateral cephalometric radiographs to examine the 1-year follow-up results of 3 different treatment methods during Class II correction. The authors evaluated the lateral cephalometric records of patients treated with the Forsus fatigue-resistant device (group 1, n = 28), cervical headgears (CHG; group 2, n = 28), and maxillary first premolar extraction with fixed orthodontic appliances (group 3, n = 28). Each group was followed at pretreatment, posttreatment, and 1-year posttreatment. The data obtained were analyzed using the 1-way analysis of variance and Kruskal-Wallis methods. At posttreatment, the ANB angle decreased significantly (P = 0.001) in the CHG group compared with the Forsus and extraction groups. The lower and upper facial heights of the CHG group were significantly increased (P
