“…To obtain the patient's dental geometry, CBCT images made before the first orthodontic wires were used. The InVesalius program was used, which, based on the shades of gray in the images, creates three-dimensional geometric structures by choosing different tissue filter from the program's database [12][13][14][15][16][17][18]. Thus, by choosing from the program menu, Bone type filter, the primary geometry for such structures can be obtained as can be seen in Fig.…”

The paper first presented the stages of obtaining a virtual model of a female patient, aged 13 years and who had multiple dental malpositions. The patient underwent a CT scan, and CT images were initially processed using the InVesalius program and three-dimensional geometries were obtained, both for the mandible and jaw, but also for the dental structure. These primary geometries were processed, edited and transformed using Reverse Engineering techniques in the Geomagic program. Dental alveoli were obtained in SolidWorks using CAD methods and techniques. Bracket elements and orthodontic wires were also generated in SolidWorks. Interference solids have been removed by various processes so that the model is geometrically accurate. Finally, these structures formed of virtual solids recomposed the orthodontic system of the analyzed patient. The custom model was exported to Ansys, where it was analyzed and result maps were obtained. Finally, interesting conclusions and some clinical observations were highlighted.

“…The number of these surfaces was 2,014,637 in this initial phase. Because I was interested in analyzing the behavior of a dentomaxillary system, the components of the upper cervical spine were removed in the next steps [13][14][15][16]. Elimination was done in several stages using direct lasso selection.…”

In order to obtain a personalized three-dimensional model of a patient based on CT images, the InVesalius program was initially used, which performs the initial conversion of the analyzed tissues into a specific engineering file composed of the so-called "point cloud". This "point cloud" was imported into the Geomagic program, in which, using reverse engineering techniques, the "point cloud" was initially transformed into elementary triangular surfaces. These primary geometric structures have been edited, transformed, adapted so that, in the end, perfectly closed surfaces are obtained. It was done in this way, both for the bone structure of the head, but also for the dental structure. These complex geometries were loaded into SolidWorks, where they were originally transformed into virtual solids. These geometric structures were loaded and assembled into SolidWorks and interference solids were removed. Finally, a customized three-dimensional model was obtained on which different normal or pathological situations can be analyzed using kinematic simulations or using the finite element method.

“…First, the images were loaded into this program to determine the scale at which they were made by the CT scanner. Because each tomographic image also contains the fixed mark (a plastic bar having a square section with the side of 20 mm), by comparing the dimensions of the real size bar dimensions to the real plastic bar, the extent to which these images were loaded into Auto-CAD so images appear on a 1: 1 natural scale [7,8].…”

The paper presents some methods used to analyze human bone joints. First, there were defined the "hard" parts as the main bone components and "soft" parts as ligaments or menisci using CT images. These components are imported into a parameterized environment assembly module and a biomechanical model of human walking is being obtained, which is exported to a kinematic simulation environment and finite element analysis, where first the kinematic parameters are defined. With these defined parameters, the kinematic and dynamic simulation of the subsystems for classical, normal motion can be switched. Following the interpretation of the results, the initial parameters of the biomechanical subsystems may be modified. In the next phase, the components of the subsystems are divided successively and the finite element structure is obtained for the entire biomechanical system of the joints that participate in human locomotion.
