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.
Highlights
Mandibular fractures are commonly observed in the clinical routine of small animals and account for approximately 3% of all reported fractures in dogs[1].The precise diagnosis of a mandibular fracture determines the appropriate treatment and prognosis of this condition
There have been several 3D models created that focus on teaching and research, we have not found any reported attempts to reproduce canine jaw fractures (CJF) in veterinary medicine
Radiography of the 3D CJF models was taken and models were generated from the mandibular bone scan
Summary
The precise diagnosis of a mandibular fracture determines the appropriate treatment and prognosis of this condition. Radiographic examination is essential for identifying the exact location and extension of the fracture, enabling appropriate therapeutic planning[2]. Undergraduate veterinary medicine fracture studies take place through books, medical images and, when there is opportunity, the follow-up of clinical cases. Despite the frequency in the clinical routine, this condition is largely overlooked during the course of study[3]. This fact may be directly related to the absence of clinical cases during study, or the limitation of teaching materials that can fully demonstrate all the aspects this condition presents[4]
