Conical implant–abutment connections are popular for their stability; however, in other conditions, such as excessive force, implants and abutments can absorb all the stress. Some connections with three points of support can resist more than conical connections. In recent years, different studies has shown that the design of a connection affects its stability. The aim of this study was to analyze and compare the stresses in finite elements (FEs) in a newly proposed conical triangular connection in implants with hexagonal and conical connections. A nonlinear 3D FE parametric model was developed using SOLIDWORKS 2017®. All the connections, i.e., external and internal hexagons, morse taper, conical connection, and the new conical triangular proposal were compared when axial forces of 150, 250, and 350 N were applied to the occlusal. The maximum stress was found in the external hexagon. The maximum stress was concentrated at the level of the neck of the abutment, implant, and bone, except for the morse taper; at the level of the crown and abutment, the lowest stress occurred in the new proposal. Conclusions: The new conical triangular (CT) connection and the conical connection (CC) generate similar stress in the implant, abutment, and crown. However, the CT connection improves the CC by reducing stress at the bone level, adding an advantage to having three retention points.

“…FEA was selected for this study because it is the method of choice for calculating the stresses involved in engineering designs and has had great impact in various biomedical applications, [12][13][14] including the design of medical devices. [15][16][17][18] We refer the reader to various excellent sources for more information on FEA and its applications in medicine and medical devices. [15][16][17][18] A solid model of one case that included an ARSD and another that did not (Figure 1) was created using Onshape software (Onshape, Boston, Massachusetts), and the FEA was carried out using SimScale (SimScale GmbH, Munich, Germany).…”

Background and Aims: The purpose of this investigation was to test the hypothesis that a novel adhesive retention suture device (ARSD) can increase perfusion at elliptical wound closures by distributing stress away from the suture site.Methods: Stress in the skin around a suture both with and without support from an ARSD was evaluated using a finite element model. A single-center, randomized splitscar comparison trial using laser speckle contrast analysis was used to quantify the perfusion at elliptical wound closures in human patients both with and without an ARSD. Results:The finite element model revealed that the ARSD promoted load transfer to the skin over a larger area, thus reducing the local stress and deformation in the skin around the suture site. Results from the split-scar study showed a mean improvement of 25% perfusion units with the ARSD, and the improvement was statistically significant (p = 0.002). Conclusion:The reduction in local stress and enhanced perfusion around the suture site reveals the potential benefit of using an ARSD to enable more efficient healing by avoiding complications associated with both low perfusion and skin tearing, such as dehiscence, infection, and cheese wiring.

“…Finite element modeling can potentially be used in many experimental studies. At present, it is widely applied in various branches of medicine [11][12][13], including orthopedics, cardiovascular surgery, and dentistry [13]. For considering food-grade applications, a high-pressure extractor was designed and analyzed using FEA.…”

Finite Element Simulation Tests of the Structural Strength of the Molding Module for Burger Production from Vegetable Outgrades

et al. 2021

The aim of the study was to assess the stresses of the structural materials of the forming module in the process of burger production from vegetable outgrades. The simulation research object was a virtual CAD 3D model of a device used for forming multi-vegetable products. Strength tests were performed on the computational model by applying the finite element method. The following were analyzed in the model: the forces exerted by the mixture of vegetables on the side walls of the tank and the dosing unit; the force from the servomotor resulting from the horizontal thickening of the vegetable mixture; the force from the servomotor resulting from the vertical mixing of the vegetable mixture; the force from the die assembly actuator; the force caused by punching the actuator from the die assembly. For evaluating the structure in the scope of the study, it was assumed that safely reduced stresses should be taken into account, with a safety factor equal to 1.1 of the yield strength of the parent material from which the structure was made (steel 1.4301 (304) with a yield stress Re0.2 of 230 MPa). For welds, safely reduced stresses should be taken into account, with a safety factor equal to 1.4 of the yield strength (Re0.2 of 230 MPa). Strength analyses confirmed that the permissible stress levels were not exceeded in the molding module.
