Comparative Analysis of Stress and Deformation between One-Fenced and Three-Fenced Dental Implants Using Finite Element Analysis

Abstract

Finite element analysis (FEA) has always been an important tool in studying the influences of stress and deformation due to various loads on implants to the surrounding jaws. This study assessed the influence of two different types of dental implant model on stress dissipation in adjoining jaws and on the implant itself by utilizing FEA. This analysis aimed to examine the effects of increasing the number of fences along the implant and to compare the resulting stress distribution and deformation with surrounding bones. When a vertical force of 100 N was applied, the largest displacements found in the three-fenced and single-fenced models were 1.7469 and 2.5267, respectively, showing a drop of 30.8623%. The maximum stress found in the three-fenced and one-fenced models was 13.518 and 22.365 MPa, respectively, showing a drop of 39.557%. Moreover, when an oblique force at 35° was applied, a significant increase in deformation and stress was observed. However, the three-fenced model still had less stress and deformation compared with the single-fenced model. The FEA results suggested that as the number of fences increases, the stress dissipation increases, whereas deformation decreases considerably.

The Stresses and Deformations in the Abfraction Lesions of the Lower Premolars Studied by the Finite Element Analyses: Case Report and Review of Literature

“…Dam Van et al [64] underlined that FEA is an important tool in implant dentistry to study the stress distribution on the adjoining bone, the biomechanics of dental implants and bone, the implant and bone interface, and their fatigue behaviors. Other authors concluded that since the experimental capabilities in implant dentistry are greatly limited by the ethical aspects of research on human subjects, FEAs are useful procedures for understanding the microdisplacements of dental implants and the mode of transmission of stresses, strains, and deformations at the bone level, with direct implications for the involved tissues [19,[65][66][67][68][69][70].…”

Air Pollution Detection Using a Novel Snap-Shot Hyperspectral Imaging Technique

“…HSI has been recently used in many industries including agriculture [31], astronomy [32], military [33], biosensors [34][35][36], remote sensing [37], dental imaging [38], environment monitoring [39], satellite photography [40], cancer detection [27,41], forestry monitoring [42], food security [43], natural resources surveying [44], vegetation observation [45], and geological mapping [46]. The visible-light hyperspectral imaging (VIS-HSI) developed in this study uses an aerial camera (DJI MAVIC MINI) image to convert the image into a hyperspectral image in the visible wavelength range of 380-780 nm and up to a spectral resolution of 1 nm.…”

Optical Identification of Diabetic Retinopathy Using Hyperspectral Imaging

“…In HSI, the data from the image are not only processed in the three visible colors but in the whole electromagnetic spectrum. HSI has been previously employed in agriculture [ 18 ], astronomy [ 19 ], military [ 20 ], biosensors [ 21 , 22 , 23 ], air pollution detection [ 24 , 25 ], remote sensing [ 26 ], dental imaging [ 27 ], environment monitoring [ 28 ], satellite photography [ 29 ], cancer detection [ 30 , 31 , 32 ], forestry monitoring [ 33 ], security [ 34 ], food security [ 35 ], natural resources surveying [ 36 ], vegetation observation [ 37 ], and geological mapping [ 38 ]. DR (DR) is one of the major complications of microvascular injury [ 39 ].…”
