Abstract
El proyecto comenzó consultando las propiedades requeridas para prototipos dentales, priorizando que se dejaran trabajar con las herramientas empleadas en odontología y se comportaran como dientes reales. La Universidad de Antioquia buscaba proporcionar a los estudiantes de odontología elementos que fueran muy semejantes a los dientes reales para sus laboratorios. Se realizaron pruebas de dureza en muestras reales, superando la dureza del aluminio. Luego, se tomaron dientes escaneados de humanos y se procesaron en programas de modelado 3D para luego imprimir en diferentes materiales poliméricos, superando desafíos técnicos en el proceso. Se realizaron también impresiones en resina de diferentes colores y se aplicaron pruebas de dureza. Aunque los dientes de resina mostraron ser duros pero frágiles, se concluyó que son adecuados para ciertas aplicaciones odontológicas. Las pruebas de laboratorio con herramientas odontológicas demostraron la viabilidad de utilizar estos prototipos para el aprendizaje práctico de los estudiantes de odontología.

The University of Antioquia sought to provide dentistry students with elements that were very similar to real teeth for their laboratories. Hardness tests were performed in real samples, exceeding the hardness of aluminum. Then, human scanned teeth were taken and processed in 3D modeling programs and then print in different polymeric materials, exceeding technical challenges in the process. Resin impressions of different colors were also made and hardness tests were applied. Although resin teeth showed to be hard but fragile, it was concluded that they are suitable for certain dental applications. Laboratory tests with dental tools demonstrated the viability of using these prototypes for practical learning of dentistry students.
