Early treatment with the twin-block appliance is effective in reducing overjet and severity of malocclusion

Abstract

Design This was a multicentre randomised controlled trial in hospital-based orthodontic practice.Intervention Children of age 8–10 years who had class II division 1 malocclusion with a minimum 7-mm overjet (measured clinically) and absence of a craniofacial syndrome were randomly allocated to receive treatment with a twin-block appliance or to an untreated, control group if they were willing to take part in the study and had parental approval to do so.Outcome measure The outcome measures were the antero-posterior relationship of the maxilla to the mandible after treatment, overjet and dental malocclusion, as recorded by the peer assessment rating (PAR).Results Early treatment with twin-block appliances resulted in reduction of overjet, correction of molar relationships, and reduction in severity of malocclusion (Table 1).Conclusions Early treatment with the twin-block appliance is effective in reducing overjet and severity of malocclusion. The small change in the skeletal relationship might not be considered clinically significant.
