Resumen: Detailed geometric models of a mandible can improve the accuracy of computer simulations. However, cost, time and qualified labor available for their construction may hinder or delay the task. The purpose of this article is to describe a technique for reconstructing a mandible with and without teeth from clinical CT scans of low resolution. The method allows modeling geometric details usually difficult to reconstruct with these scans, such as the periodontal ligament. The models of a toothless and toothed mandible resulting from the process are available online for non-commercial use. The models can be used in various fields such as orthodontics, implantology, orthopedics and traumatology as presented or as a basis for simulations.
