Vol. 14 – Number 55 – 2021 Case report Page 55-66 3D biomechanical planning in Class II treatment – how to benefit from side effects – case report Adriana Maria Bonadio Lopes Ramos¹ Lincoln Leonel Ramos² Armando A. de Mendonça¹ Edimilson Ramos¹ Wislei de Oliveira³ Abstract Orthodontic treatment in adult patients today is part of clinical practice routine. The aesthetic request, increased life expectancy and accessibility to treatment caused the demand for adult patients to increase exponentially. The purpose of this work is to present the threedimensional (3D) and orthodontic mechanics of the correction of Angle Class II division 2 malocclusion with deep overbite and extruded molars, through a clinical case, in which side effects of intrusion mechanics were used, associated to the torque arc in favor of vertical anteroposterior correction, as well as correction of the upper molars extrusion, that is, the use of associated force systems in order to facilitate and mechanically accelerate the treatment. Treatment planning was carried out with T3D Occlusogram and DDP program.
