Abstract

The aim of this case report presents a case of
skeletal II and dental Class II divisional I treated
with functional appliance in a male patient with
increased overjet. A 9-year-11-month-old male
patient was admitted to our clinic with lower jaw
retention. Clinical and radiographic evaluation
revealed skeletal class II and dental class II division
I anomaly and increased overjet due to mandibular
retrognathie. The treatment was started with rapid
maxillary expansion. After the retention period of 6
months, the treatment was continued with activator
appliance to correct mandibular retrognathia.
Mandibular advancement and class I molar and
canine relationship were achieved after 10 months
of activator use. In conclusion, in the case of
dental class II division I, increased overjet, rapid
maxillary expansion and functional treatment with
activator appliance resulted in a good occlusion
with normal overbite and overjet with dental class
I relationships.
