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

Abstract

This paper aimed at reporting the creation of brachycephalic and dolichocephalic 3D synthetic anatomical models of canine heads (3D SAMCH) as a complementary technique to traditional osteotechnique using Computed Tomography (CT) images in volumetric reconstruction. The study was carried out in three stages, namely: a) preparation of canine heads in natura; b) creation of digital files of canine heads using CT; and c) 3D printing of synthetic anatomical models of canine heads. As a result, two 3D SAMCH were produced due to rarer availability in Animal Anatomy laboratories collections; the important representation of the cribriform plate was possible, but a remarkable defect presented was the teeth. It concluded that the digital files creation through CT scanner allows a fine representation of canine heads if considered pros and cons regarding the use of synthetic models instead of natural bones.

Prototyping and 3D Printing of Computed Tomography Images with an Emphasis on Soft Tissues, Especially Muscles, for Teaching Human Anatomy

“…The applications of this technique in the teaching of human anatomy still have a limited literature, with most studies being carried out through digital bone scanning (Thomas et al, 2016;Bartikian et al, 2019;Massari et al, 2021), and more rarely, soft tissue (Anwari, 2020;Tan et al, 2022).…”

3d Printing as a Tool in Anatomy Teaching

“…In studies carried out in Brazil, a critical analysis of contents for teaching topographic anatomy, intends to implement new teaching technologies with the possibility of adaptations which meet the expectations of students and the real needs of the course and the job market. It is important to mention that the morphological characteristics of an organic anatomical structure, in a synthetic object, in the construction of 3D didactic models involves virtual and physical steps [3], [4].…”
