Lack of retention and stability is one of the major complaints of edentulous patients. Treating older patients, especially those with disabilities, may be a demanding challenge. The implant with Hader bar attachment with a 3 mm stiffener is the best in terms of stress distribution, where the stress is concentrated at the bar and stiffener regions.Īs life spans lengthen, a significant number of people outlive their teeth. In model C the maximum stress concentration was in the bar attachment making it the model with the best stress distribution, as far as implant failures are concerned. The results showed that the maximum stress concentration was seen in the neck of the implant for models A and B.

These different models were analyzed by the Finite Element Software (Ansys, Version 8.0) using von Mises stress analysis. A CT scan of edentulous mandible was used and three models with 1, 2, and 3 mm thick stiffeners were created and subjected to loads of emulating the masticatory forces. The stiffener of the bar attachments was varied and the stress distribution to the bone around the implant was studied. This study aims to analyze the force transfer and stress distribution of an implant-supported overdenture with a Hader bar attachment. But the ideal thickness of the stiffener to be attached to the bar is a subject of much debate. The effect of adding a stiffener to the tissue side of the Hader bar helps to reduce the transmission of the stresses to the alveolar bone. A key factor for the long-term function of a dental implant is the manner in which stresses are transferred to the surrounding bone.

At suitable points in the lectures, we interrupt the mathematicalĭevelopment to lay out the code framework, which is entirely open source, and C++ based. Questions that arose from a small group of graduate students and post-doctoral scholars whoįollowed the lectures live. Interspersed among the lectures are responses to

Three dimensions (linear elastodynamics). (unsteady heat conduction and mass diffusion), and the lectures end with hyperbolic PDEs in Parabolic PDEs in three dimensions come next In vector unknowns (linearized elasticity). Mass diffusion), before ending the treatment of elliptic PDEs with three dimensional problems Then move on to three dimensional elliptic PDEs in scalar unknowns (heat conduction and One dimension (linearized elasticity, steady state heat conduction and mass diffusion). For clarity we begin with elliptic PDEs in The physical phenomena represented by the PDEs. At each stage, however, we make numerous connections to The development itself focuses on the classical forms of partial differential equations (PDEs):Įlliptic, parabolic and hyperbolic. A background in PDEs and, more importantly, linear algebra, is assumed,Īlthough the viewer will find that we develop all the relevant ideas that are needed. Much of the success of the FiniteĮlement Method as a computational framework lies in the rigor of its mathematicalįoundation, and this needs to be appreciated, even if only in the elementary manner Methods, which in turn explains why they work so well. We do spend time in rudimentary functionalĪnalysis, and variational calculus, but this is only to highlight the mathematical basis for the It is notįormal, however, because the main goal of these lectures is to turn the viewer into aĬompetent developer of finite element code. Natural for a topic whose roots lie deep in functional analysis and variational calculus. Introductory graduate class at University of Michigan. The course includes about 45 hours of lectures covering the material I normally teach in an

The emphasis is on coding up the formulations in a modern, open-source environment that can be expanded to other applications, subsequently. The treatment is mathematical, but only for the purpose of clarifying the formulation. This course is an introduction to the finite element method as applicable to a range of problems in physics and engineering sciences.
