| The maxillary sinus (MS) is described as a pyramid-shaped cavity of the maxilla. Knowledge of its morphology makes it possible to define normality and abnormality so that its three-dimensional analysis can be a valuable preoperative tool during surgery in this anatomical area. The aim of this study is to present a strategy of morphological analysis of the MS using 3D printing acquired through computed cone beam tomography (CBCT) images. A cross-sectional descriptive study was conducted, including 15 subjects (8 women and 7 men). The 3D virtual reconstruction and modeling was done on the MSs bilaterally, and 30 physical models were produced on a 3D printer. The results revealed that the MSs obtained exhibited various morphologies. An individual analysis of... |

| The planning and 3D reconstruction in craniofacial defects based on anatomical principles of symmetry and passive adaptation has evolved radically the past few years. This article recounts the possibility to develop personalized and extensive craniofacial implants. We present a case of a patient with a 10-year trauma sequel evolution; the patient lost the right frontal bone, supraorbital wall and part of the temporal fossa. From the computerized tomography, and by using Materialise software (3-Matic and Mimics). Subsequently, the printing was performed using the virtual planning with a laser printer in titanium where the piece was elaborated with the determined specifications in the planning; surgery was performed without complications in which the implant... |

| ABSTRACT: 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... |
