Abstract

BACKGROUND: Because the subjects of functional appliance are young people in the growing period, children’s growth and Department of

Orthodontics, First

development need to be considered to study whether the functional appliance is valid. Affiliated Hospital of

OBJECTIVE: To build a mathematical model to analyze the correlation between craniofacial soft and hard tissues after the Hebei Medical

correction of Class Ⅱ malocclusion with twin-block treatment. University,

METHODS: Thirty-one Class Ⅱ Division 1 malocclusion subjects with hand-wrist radiographs in FG-G stage were selected. Shijiazhuang

050031, Hebei

Among the 31 cases, 14 abandoned treatment. The remaining 17 subjects received Twin-block treatment. All the subjects were Province, China;

taken cephalometric radiographs before and after twin-block treatment as well as before and after natural growth of hard and soft 2Basci Medical

tissue to observe the variation rule of soft and hard tissue cephalometric values so as to buil
