dc.description.abstractPurpose of this study is to evaluate the effects of Forsus Fatigue-Resistant Device (FRD) EZ and Andresen activator in terms of skeletal, dental, and soft tissue changes in actively growing patients presenting with class II, division 1 malocclusion. Study sample included 60 subjects. Inclusion criteria were as follows: class II division 1 malocclusion, retrognathic mandible, normal or low-angle growth pattern, and peak growth period. The first study group consisted of 20 patients who were treated with Forsus appliance, and the second group of 20 patients received treatment with Andresen activator. Control group received no treatment. Our results revealed that both appliances enhanced mandibular growth, helped increase the length of the mandible, and had a restraining growth effect on the maxilla. Anterior face height increased in both of treatment groups, whereas posterior face height had a significant increase in the activator group only. More mandibular incisors protrusion and intrusion were seen with the Forsus appliance. Moreover, occlusal plane and palatal plane rotated significantly in clockwise direction as a result of dentoalveolar changes only in the Forsus group. As well as the Forsus appliances corrected class II discrepancies mostly through dentoalveolar changes as compared to the activator group, both appliances proved effective in the treatment of growing individuals having class II malocclusions with mandibular retrognathia. By this investigation, two treatment methods, which are currently used in clinical practice, will be evaluated, and the results will be useful for clinicians.en_US
