Printing 3D models of canine jaw fractures for teaching undergraduate veterinary medicine

Abstract

Purpose To develop 3D anatomical models, and corresponding radiographs, of canine jaw fractures.Methods A base model was generated from a mandibular bone scan. With this model it was possible to perform fracture planning according to the anatomical location.Results The 3D base model of the canine mandible was similar in conformation to the natural bone, demonstrating structures such as canine tooth crowns, premolars and molars, mental foramina, body of the mandible, ramus of the mandible, masseteric fossa, the coronoid process, condylar process, and angular process. It was not possible to obtain detail of the crown of the incisor teeth, mandibular symphysis, and the medullary channel. Production of the 3D CJF model took 10.6 h, used 150.1 g of filament (ABS) and cost US$5.83.Conclusion The 3D canine jaw fractures models, which reproduced natural canine jaw fractures, and their respective radiographic images, are a possible source of educational material for the teaching of veterinary medicine.

3D models of nonunion fractures in long bones as education tools

“…These images allowed the main points of the representations of the different models of nonunion fractures to be preserved. These findings corroborate those of Li et al (2018), who produced three 3D models (i.e., rib, femur, and cervical vertebra of a bovine) and Lima et al (2019), who produced a 3D canine jaw. The studies mentioned describe and emphasize how the precision and quality of scanning influences the process of creating anatomical models.…”

3D printing of brachycephalic and dolichocephalic canine skulls and mandibles: a complement to traditional osteotechnique

“…It is worth mentioning that the use of tomographic images of the skulls allowed the representation of the cribriform plate of the ethmoid bone in 3D SAMCH. Our research corroborates Lima et al (2019), who claim that the use of images generated by medical scanning (such as CT) are crucial for the internal representation (and difficult to access during a dissection) of anatomical bony structures.…”

“…In this field, it has already been used in orthopedic implants production (CASTILHO et al, 2014), clinical training (O 'REILLY et al, 2016, preclinical radiotherapy (MCCAROLL et al, 2015), surgical planning (KIM et al, 2018), and education. In this latter, it includes studies in anatomy (LI et al, 2018), clinic (LIMA et al, 2019), diagnostic imaging (NUNEZ et al, 2020), surgery (CARVALHO et al, 2019), and anesthesiology (NEVES et al, 2020). However, there are no studies that correlate the morphology of different types of skulls in dogs and their 3D printing as a tool for teaching-learning canine anatomy.…”

“…These kinds of 3D printing models are printed hollow. Researchers can fill inside of the model by themselves (8,11,13). The scanning was not applied superficially in this study.…”

“…3D printing models are easier to understand than 2D drawings or figures. In this case, the 3D printing model has become an important educational tool in anatomy, pathology, and surgery education (8,11,13,15).…”
