Rapid prototyping (RP) is an innovative technology that allows one to obtain a prototype of a mold quickly and accurately from a virtual model. This study aimed to establish the use of photogrammetry and 3D prototyping for the production of bone biomodels of the canine species for training in orthopedic techniques in veterinary medicine. Virtual bio-modelling was performed by the photogrammetry technique with commercial anatomical pieces, and physical biomodelling was performed by 3D printing. Osteotomies were performed on the biomodels that served as platforms for osteosynthesis of the femur and ileum, and the final product was not associated with a risk of biological contamination, was able to support special orthopedic materials, and was used for training and surgical planning. We concluded that the use of photogrammetry and RP for the production of bone biomodels of the canine species enabled techniques for fracture reduction to be performed with the use of special instruments, enabling training in the area of veterinary orthopedics in an economically viable manner with an alternative to experimental animals.
Congenital anomalies are hereditary or acquired, and their location and intensity are determining factors for the survival of animals. Some cases are rare, often unidentified, poorly reported and of unknown etiology. This paper reports a congenital malformation in a French bulldog, demonstrating the importance of accurate diagnosis for surgical decisions. The use of new technologies such as computed tomography and rapid prototyping enables the analysis of morphofunctional changes, resulting in excellent results for clinical cases in which it is difficult to identify and scale the anatomical deformities. Through this feature, it is possible to accurately recreate anatomical structures of interest, enabling greater assertiveness in deciding the treatment to be established, whether surgical or not. Castration of animals that survive this condition due to hereditary etiology is recommended.
Medical images combined with 3D printing techniques have been a differential for clinical surgical and didactic approaches. The segmentation of anatomical structures in medical images for their 3D printing of biomodels has been showing promise in medical applications. The use of iodine contrast in solution on anatomical specimens promotes an increasing the density and better caption resolution of CT, expanding the range of possibilities for 3D medicine. With the capture of a complex anatomical arrangement, there is an advantage over the use of biomodels both in a digital and physical interactive way. In this article, we explain how to digitize a set of anatomical structures of the canine urogenital system in topographic position and how to create 3D digital and printed replicas. The biomodel can be applied in the most diverse areas of veterinary medicine and related fields.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
