The accuracy of visualized treatment objectives in bimaxillary protrusion patients
Abstract
The aim of this research project was to assess the accuracy of four different types of VTO [Steyn (1979), Jacobson and Sadowsky (1980), Ricketts (1982) and Holdaway (1984)], in predicting the final result of the incisor and soft tissue response to orthodontic treatment in bimaxillary protrusive patients.
