Abstract
This present paper describes 3 clinical cases which were treated with Bioprogressive mechanism. Each patient has shown a deficient maxilla combined with prognathic and steep mandible. The purpose of treatment was planned to obtain the forward growth of maxilla and redirectioning of mandibular growth. The most noteworthy approach in the treatment was the application of Cl III intermaxillary elastics with upper protraction utility arch immediately after rapid maxillary expansion. In the analysis of the data obtained from pre- and post treatment lateral cephalogram, the result achieved by this method is very favolable to the correction of anteroposterior relationship of maxilla and mandible.
