3D Print of the Maxillary Sinus for Morphological Study International Journal of Morphology
Araneda,Nadia; Parra,Marcelo; Valdivia Osorio,José; Olate,Sergio.
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...

Anatomical Reproducibility through 3D Printing in Cranio-Maxillo-Facial Defects International Journal of Morphology
de Moraes,Paulo Hemerson; Olate,Sergio; Cantín,Mario; Assis,Adriano Freitas; Santos,Edson; Silva,Filipe de Oliveira; Silva,Lucas de Oliveira.
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...

Generation of 3D Tooth Models Based on Three-dimensional Scanning to Study the Morphology of Permanent Teeth International Journal of Morphology
Cantín,Mario; Muñoz,M; Olate,Sergio.
The dental student should have thorough knowledge of the dental morphology and develop adequate manual skill to reproduce any part of the tooth, thus maintaining the perfect correlation with associated structures. Computers are becoming an integral part of dental education and dental practice, especially for the acquisition of information in three dimensions and the production of solid objects from computer models. The aim was to present educational material that would allow the dental student to learn to easily identify the morphologic characteristics of permanent teeth, using new technological tools. In order to do this, healthy permanent teeth were scanning by NextEngine 3D Scanner HD using the MultiDrive. A 360° scan in macro range was chosen in each...
