The treatment of Class II division 1 by jaw upper disorder is a controversial subject in the literature. This study aims to evaluate, through the PAR Index (Peer Assessment Rating), orthopedic treatment of Class II malocclusion division 1 in 15 patients of both sexes who have made growing use of the appliance Thurow modified. This study consisted of a retrospective longitudinal clinical study with no control group. The average age of patients at the start of treatment was 9.3 years for females and 9.4 years for males. The PAR index was obtained from pre and post treatment of each patient. An improvement of 31% or more was considered effective treatment. After descriptive analysis, it was observed that the initial average PAR index of 33 was reduced to 18.5 at the end of treatment, featuring an improved occlusion averaged 43.9%. The treatment was effective in 86.7% of patients, no statistical difference was observed in relation to sex and age at start of treatment (p> 0.05). It was also found that the apparatus provided significant changes in overjet correction (p <0.05). From this study it can be concluded that the orthopedic treatment of Class II division 1 with modified Thurow appliance in growing patients presented a viable alternative, and we observed an improvement of occlusal relationships primarily with respect to overjet and molar relationship towards anteroposterior.
