简要总结
Objective: The purpose of this study was to compare the clinical effectiveness of reducing severe overjet in Angle Class II division 1 malocclusion between Activator and the EF (Functional Education) class II standard in treating.
Methods: A randomized clinical trial was conducted on a total of ̉60 patients with an Angle Class II, division 1 malocclusion (ANB angle ≥ 4°, basic normal maxillary status), and an overjet of ≥ 6 mm in the developmental stage (CS1-CS3) who were eligible for the study. Thus, the sample consisted of 60 subjects (29 girls and 31 boys) with a mean age of 9.7 ± 1.31 years. The investigators designed the study to treat patients, randomly assigning them by lottery to receive either an activator or the EF (Functional Education) class II standard. The activator versus the EF (Functional Education) class II standard group consisted of 30 subjects (17 girls, 13 boys) and 30 subjects (12 girls, 18 boys), respectively. The changes in skeletal, dental, and soft tissue were recorded before, at 6 months of treatment. Blinding was not performed. After six months of treatment, the study's endpoint was reached.

A randomized clinical trial was conducted on a total of ̉60 patients with an Angle Class II, division 1 malocclusion, and an overjet of ≥6 mm who were eligible for the study. Thus, the sample consisted of 60 subjects (29 girls and 31 boys) with a mean age of 9.7 ± 1.31 years. We designed the study to treat patients, randomly assigning them by lottery to receive either an activator or the EF (Functional Education) class II standard. The activator versus the EF (Functional Education) class II standard group consisted of 30 subjects (17 girls, 13 boys) and 30 subjects (12 girls, 18 boys), respectively. The changes in skeletal, dental, and soft tissue were recorded before, at 6 months of treatment. Blinding was not performed. After six months of treatment, the study's endpoint was reached and then selected those who achieved the standards for sampling at Can Tho University of Medicine and Pharmacy. The Can Tho University of Medicine and Pharmacy Ethics Council in Biomedical Research No. 23. 340.HV/PCT-H signed the study on April 12, 2023.

主要结局
To compare the clinical effectiveness of reducing severe overjet in Angle Class II division 1 malocclusion between Activator and the EF (Functional Education) class II standard in treating.
时间窗: 6 months
Every month, the research participants from both groups underwent regular re-examinations, during which they collected cephalometric radiographs for assessment at two specific time points: T0, before treatment, and T1 after 6 months of treatment. A Planmeca ProMax® 2D digital X-ray system (Planmeca, Poland) captured the cephalometric radiographs. The Dental Hospital used the licensed AudaxCeph program to accurately draw lines and perform measurements on the cephalometric images.
