“…In addition, new and efficient production process, based around rapid prototyping (RP) technologies, is currently revolutionizing the generation of physical models [2]. In recent years, the advances in computing technologies and production processes, both terms of hardware and software have led to the using of Computer Aided Design (CAD) in biomedical engineering that is a technological field, which includes medicine engineering, tissue engineering, genetic technology, medical treatment engineering [3], in applications, ranging from clinical medicine, and customized medical implant to tissue engineering [4].…”

The purpose of this study is to prepare a model of the human mandible in accordance with anatomical structure and fabricated by rapid-prototyping (RP) technology. In this study, a computed tomographic (CT) scan of a dentate mandible was obtained with a 0.3 mm voxel resolution with capability to export to DICOM format. The data were cleaned; edited and separated 'mask' generated for cortical bone, cancellous bone, and teeth using Mimics 10.01 and Geomagic 11.0 software. The data were imported to Solidworks from Geomagic and converted to the solid model and fabricated by 3D rapid-prototyping technique. The mandible structure was divided into layers and then an average Young's modulus value was calculated for each layer of cortical bone and cancellous bone using the basis of CT density as in previously published protocols. In this study, the procedure of obtaining bio-CAD model of mandible methodology has nine phases: computed tomography (CT), 2D segmentation, calculating 3D object from scanned data, reverse engineering interface, point cloud data processing, surface reconstruction, solid model reconstruction, obtaining bio-CAD model, and fabricating the model using RP technology. The average Young's Modulus value of cortical bone and cancellous bone was calculated 30100.88 MPa, and 685.42 MPa, respectively. As a result, according to expert review, examination of the anatomical structure, and literature survey, we concluded that the development of 3D human mandible model can be used to conduct research on human mandible.

“…A 3D model is a manufactured model made by a 3D printer using digital imaging and communication for medicine (DICOM) data from a computed tomography (CT) scan, and then, converted into computer-assisted design (CAD) data [3,[4][5][6][7]. To illustrate an example of a 3D model, Fig.…”

“…To accommodate the need for precision pre-operative planning, surgeons frequently need guidance such as a threedimensional (3D) model to display complex cranial structures [2,3]. Over the past decade, 3D models have been employed widely in maxillofacial surgery [4]. This has tended to concentrate on the reproduction of exact physical replicas of patients' skeletal anatomy, which surgeons and prosthetic experts use to help plan reconstructive surgery and prosthetic rehabilitation [5].…”

Objective: The objective of this study is to compare fabrication of commonly used three-dimensional (3D) models with original multislice computed tomography (MSCT) scan data for accuracy and precision in reconstruction surgery.Methods: MSCT data from 10 samples are processed and manufactured to be 3D models. Both groups are then measured and analyzed for the purpose of comparison. Results:The average mandibular measurement difference between 3D models and MSCT scans is 0.26 mm more <2%. The final results of the comparison reveal high accuracy in 3D models compared to MSCT scan data. Conclusion:The 3D model could be considered as surgical guidance for maxillofacial reconstruction surgery since it yields highly accurate results.

Influence of processing parameters on mechanical properties of a 3D‐printed trabecular bone microstructure

Natural bone microstructure has shown to be the most efficient choice for the bone scaffold design. However, there are several process parameters involved in the generation of a microCT‐based 3D‐printed (3DP) bone. In this study, the effect of selected parameters on the reproducibility of mechanical properties of a 3DP trabecular bone structure is investigated. MicroCT images of a distal radial sample were used to reconstruct a 3D ROI of trabecular bone. Nine tensile tests on bulk material and 54 compression tests on 8.2 mm cubic samples were performed (9 cases × 6 specimens/case). The effect of input‐image resolution, STL mesh decimation, boundary condition, support material, and repetition parameters on the weight, elastic modulus, and strength were studied. The elastic modulus and the strength of bulk material showed consistent results (CV% = 9 and 6%, respectively). The weight, elastic modulus, and strength of the cubic samples showed small intragroup variation (average CV% = 1.2, 9, and 5.5%, respectively). All studied parameters had a significant effect on the outcome variables with less effect on the weight. Utmost care to every step of the 3DP process and involved parameters is required to be able to reach the desired mechanical properties in the final printed specimen. © 2019 The Authors.
