How-to Column – Use of open source software for virtual treatment planning

Vol. 14 – Number 53 – 2021 How-to Column Page 14-21 Use of open source software for virtual treatment planning Caroline Pelágio Maués Casagrande1 David Silveira Alencar2 Diego Junior da Silva Santos3 José Augusto Mendes Miguel4 Abstract The orthodontic setup is a tool used for tridimensional simulation for visual treatment planning. Its analysis allows to plan the mechanics to be used during the orthodontic treatment. For this purpose, it is necessary to duplicate the cast model, to cut the teeth and replace them in their respective cast bases. However, this process demands laboratory time and physical space for cast models storage. The traditional setup with cast models has been substituted by the 3D virtual version once it does not demand physical space for storage. Despite the learning curve, the 3D virtual computerized process has a reduced time when compared to the setup with cast models. But the software high cost is still the main point of disadvantage for its use. Thus, the aim of this study is to describe a step-by-step of 3D virtual orthodontic setup process, by using an open-source software.
