Application of two segmentation protocols during the processing of virtual images in rapid prototyping: ex vivo study with human dry mandibles

Abstract

Virtual processing of CT images is the most complex stage during the manufacture of the biomodel. Establishing a better protocol during this phase allows the construction of a biomodel with characteristics that are closer to the original anatomical structures. This is essential to ensure a correct preoperative planning and a suitable treatment.

Three-Dimensional Digitalized and Printed Tongue Models of the Cow, Dog, Pig, and Horse for Undergraduate Veterinary Educationh

“…Students who used physical models for identifying the anatomical structures of the horse hoof recalled information better than those who used books and/or virtual models. The use of 3D models has been promoted for the training and qualification of medical professionals.Its benefits include assisting in diagnosis, surgical planning, and reductions in the length of operative procedures, the period of anesthesia, the risks of infections, the number of surgeries necessary to obtain a final result and the overall costs of a treatment.Studies have also presented the possibility of 3D printing of biomaterials, cells, and components of tissue supports used in regenerative medicine (Paiva et al, 2007;Robiony et al, 2007;Meléndez-Álvarez, 2009;Ferraz et al, 2013;Thomas et al). The aim of the present study was to build 3D virtual and physical models of the tongues of different domestic mammalian species (cow, dog, horse, and pig) in order to construct a didactic collection for the study of veterinary anatomy.…”
