This book was released on 2017 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined the effect of using two anterior denture-supporting mini implants (mIMP2) compared to four (two anterior and two posterior) denture-supporting mini-implants (mIMP4) on the stress experienced by the mini-implants and the strain experienced by the peri-implant and analogous posterior bone. The stress and strain values were also compared to known values of strength for the mini-implants and physiologic strain values. Finite element modeling was used to study the effects. Two models were created identically, with the exception of the number of denture-supporting mini-implants used, and contained modeled mucosa, cortical bone, cancellous bone, and the mini-implants. The models were loaded over one second with three 70N loads bilaterally and results with collected using a PostView program. The anterior mini-implants in both models showed stresses that would not put them at risk for fracture. The posterior mini-implants in mIMP4 experienced stresses above their yield point, indicating that they could be at risk for fracture. Strain in the peri-implant bone anteriorly and the posterior bone in mIMP2 was in the physiologic range. The posterior peri implant bone in mIMP4 showed strains that were above physiologic, which indicates this region could be at risk for bone resorption. Based on the limitations of this study, posterior mini-implants and posterior peri implant bone could be at risk for fracture and pathologic resorption. Dentists must weigh the risks and benefits of using mini-implants to support overdentures in each clinical case to determine if the treatment could be successful in light of the potential negative consequences.

Available in PDF, EPUB and Kindle. Book excerpt: In dentistry, instead of conventional prosthetic applications, dental implant prosthesis has recently been used in edentate patients. Biomechanical effects are known to be one of the most important factors in the failure of these implants. In this work, a three-dimensional model of the edentate mandible is formed to use in three-dimensional finite element method for the stress analysis of chewing forces. The computerized three-dimensional solid geometric mandible model is formed by using commercially available CAD tools on a series of two-dimensional CT images obtained from a Hi-speed CT/I imaging system. Satisfactory results on several implant schemes on this model are obtained by applying various critical chewing forces. Keywords - Three-dimensional finite element model, CT images, mandible.

Download or read book Perusal of the Finite Element Method written by Radostina Petrova and published by BoD – Books on Demand. This book was released on 2016-12-14 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The finite element method (FEM) is a numerical technique for finding approximate solutions to different numerical problems. The practical applications of FEM are known as finite element analysis (FEA). FEA is a good choice for analyzing problems over complicated domains. The first three chapters of this book contribute to the development of new FE techniques by examining a few key hurdles of the FEM and proposing techniques to mitigate them. The next four chapters focus on the close connection between the development of a new technique and its implementation. Current state-of-the-art software packages for FEA allow the construction, refinement, and optimization of entire designs before manufacturing. This is convincingly demonstrated in the last three chapters of the book with examples from the field of biomechanical engineering. This book presents a current research by highlighting the vitality and potential of the finite elements for the future development of more efficient numerical techniques, new areas of application, and FEA's important role in practical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Finite Element Analysis represents a numerical technique for finding approximate solutions to partial differential equations as well as integral equations, permitting the numerical analysis of complex structures based on their material properties. This book presents 20 different chapters in the application of Finite Elements, ranging from Biomedical Engineering to Manufacturing Industry and Industrial Developments. It has been written at a level suitable for use in a graduate course on applications of finite element modelling and analysis (mechanical, civil and biomedical engineering studies, for instance), without excluding its use by researchers or professional engineers interested in the field, seeking to gain a deeper understanding concerning Finite Element Analysis.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background;Slight offset of the central implant in 3-unit implant-supported prostheses has been recommended to improve biomechanical behavior.However, studies that assessed the effects of an offset implant congfiguration in the posterior mandible are rare.Aim/Hypothesis;The purpose of this 3-dimensional (3D) finite element study was to assess the effects of load direction and number of implant in 3-unitimplant-supported prostheses with varying implant positions (straight-line or offset) on the stress distribution in the implant,prosthesis, and bone tissue.Materials and Methods;Three 3D models were used to simulate a posterior mandible bone block: 2 implants and 3-unit fixed dental prosthesis(FDP) with apontic in the middle (model M1), 2 implants and 3-unit FDP with a cantilever pontic at one end (model M2), FDP supported by 3implant with straight line placement (model M3) and FDP supported by 3 implant with staggered implant configuration (model M4).The applied forces were 120 N axially (L1), or 120 N obliquely(L2). The type of implant platform simulated was an external hexagon.Maximum von Mises stress (VMS) on the fixture, abutment, screws, fixed prosthesis and supporting alveolar bone was measured andanalyzed.Results;Peak VMS in the implants by oblique loading were 10-25 times greater in implant and 6-12 times greater in alveolar bone,respectively than the stresses by axial loading.Compared to the maximum stress value of the implant by oblique loading in model M1, the maximum stress value increased to 116%in M2, but decreased to 74% and 71% in M3 and M4, respectively.In the cantilevered M2 model, the maximum stress values in the FDP were 851.5 and 908.4 MPa, respectively, by the vertical andoblique loadings, which are 5.1 and 7.1 times higher than the other models, respectively.The area of maximum stress in the implant was located around the area where the abutment screw and fixture were connected.Stress concentration was observed at an abutment screw by oblique load and at the top of the implant fixture by axial load.In the supporting bone, the maximum stress value increased to 120% in M2, but decreased to 69% and 63% in M3 and M4,compared to the stress in M1 by oblique load.Conclusions and Clinical Implications;The effect of staggered alignment on implant stress was negligible, but the cantilever design of the prosthesis and the number ofimplants had a greater impact on stress distrubution.
