Abstract

Background: Functional appliances are now widely used in the treatment of Class II Division 1 malocclusion in growing children. Objectives: To describe the clinical characteristics, radiographic features of bone, teeth, and soft tissue on lateral cephalograms of Class II Division 1 malocclusion patients treated with functional appliances at the Ho Chi Minh City Dental Hospital in 2023-2024. Materials and methods: A cross-sectional descriptive study on 60 patients aged 7 to 12 years diagnosed with Class II Division 1 malocclusion, who visited and were treated at the Department of Orthodontics – Ho Chi Minh City Dental Hospital from April 2023 to June 2024. Results: Patients with class II division 1 malocclusion showed class II skeletal relationship (ANB angle of 5.03 ± 1.65°) due to mandibular retrognathism (SNB angle of 79.0 ± 3.18°), maxillary incisors were proclined and protruded (U1-SN angle of 116.6 ± 9.58°, U1-NA angle of 32.6 ± 8.88°, U1-NA distance of 7.06 ± 2.74 mm), increased overjet (8.15 ± 2.3 mm), sharp nasolabial angle (94.69 ± 11.93°), and both upper and lower lips protruded relative to the E-line (Ls-E line distance of -2.37 ± 1.69 mm, Li-E line distance of -2.79 ± 2.41 mm). Conclusion: Patients with class II division 1 malocclusion exhibited a class II skeletal relationship due to mandibular retrognathism.
