Patients in mixed dentition were treated by bioprogressive therapy. In the first case headgear was applied for orthopedic alteration and in the second case headgear was applied for the maximum anchorage of buccal segments. In both cases visual treatment objectives (V. T. O.) were almost achieved. As a result, patients attained proper chin control, stable occlusions, and favorable profiles. It was recognized that the V. T. O. was valuable to forecast the growth of the patient and the anticipated effects of treatment, as well as to evaluate the results achieved at the end of treatment.}, pages = {273--283}, title = {Bioprogressive Therapyを用いた上顎前突の2治験例}, volume = {19}, year = {1993} }
