Book A Three Dimensional Numerical Interaction Model for the Fixation of Mandibular Fractures

Download or read book A Three Dimensional Numerical Interaction Model for the Fixation of Mandibular Fractures written by and published by . This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two and three dimensional finite element models (FEM) were developed to simulate the behavior of a fractured jaw bone and the fixation materials. Mini-plates with various geometric and material properties and screw combinations were considered. Their effects on the variation of maximum stress contours were investigated. The geometric and material properties of the plate screw and bone were seen to play important roles in effecting the relative displacement at the fractured surface and the spatial variation of the maximum stress across the jaw bone. Softer materials yielded less stress concentrations around the screws while increasing the relative deformation at the fractured surface and stiffer ones caused higher stress concentrations while decreasing the displacements. Results were also seen to be dependent on the loading and the need for the use of patient specific 3D solutions was emphasized.

The main focus of this thesis is the implementation of a bone remodeling algorithm in MATLAB and ANSYS on the basis of FEM. The strain energy density is used as mechanical stimulus. The cortical and trabecular bone are described as continuous materials with variable density. This thesis can be divided into four main parts. The first part is due to the material properties of cortical and trabecular bone. The second part is about the remodeling theory and gives an historical review of the developed numerical approaches up to now. The implementation of the remodeling algorithm in ANSYS and MATLAB as well as its validation is topic of part three. In last main part, the algorithm is applied to a 2D FE-model of a human proximal femur.

Book Current Controversies in Temporomandibular Disorders

Download or read book Current Controversies in Temporomandibular Disorders written by Craniomandibular Institute. Squaw Valley Winter Seminar and published by Quintessence Publishing (IL). This book was released on 1992 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume discloses the various and, at times, conflicting views regarding temporomandibular disorders (TMD) as presented at the Craniomandibular Institute's 10th Annual Squaw Valley Winter Seminar held in January 1991. The field of TMD has been long on testimonials and clinical opinion but short on scientific documentation. As a result, there is presently a growing concern in the field that scientific foundation is needed to support the various belief systems and to improve credibility. This seminar encouraged participants to openly discuss and expose the controversial issues plaguing the field and to provide clinical and basic research to support or to question those issues. To this end, 14 internationally renowned experts assembled to discuss the current status of terminology, epidemiology, etiology, diagnoses, and management for TMD. This book is divided into four main parts, each of which helps to provide the reader with a better understanding of the complexity of TMD. A wide variety of scientific evidence, clinical experience, and informed opinions is presented. This variety will ensure that the volume will serve as the foundation for future discoveries in the study of TMD. As such, this book will be of interest to all who work within the field.

Book Three dimensional Finite Element Analysis of Internal Conical Joint Implant supported Fixed Prostheses in the Posterior Maxilla

Download or read book Three dimensional Finite Element Analysis of Internal Conical Joint Implant supported Fixed Prostheses in the Posterior Maxilla written by and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: There are various implant placement options, such as using a short implant or changing the direction of the implant placement to use more residual bone. Currently, the connection design between implant fixture and the abutment is in two forms: external hex type and internal conical type. The biomechanical information on the various implant systems and various implant placement option is not sufficient to determine reliable treatment plans and implant choices.This study aimed to compare the functional stresses generated in the internal conical joint implant, prosthesis and supporting bone in the posterior maxilla, using finite element method.Two internal joint type implant (u00d85 X 7mm, u00d85 X 13mm) with TS2 SA fixture design of Osstem (Seoul, Korea) were modeled by computer-aided design software (Solidwork 2018). The posterior maxillary bone and 3-unit all zirconia crowns were also simulated. Three different scenarios were modeled with various implant alignment (SI3; 3 unit fixed prosthesis on 3 short implant abutments, SI2; 3 unit fixed prosthesis on 2 short (7mm) implant abutments, AI2; 3 unit fixed prosthesis on 1 short implant abutment and 1 long (13mm) implant with an angled abutment). A load of 30 N was applied vertically and obliquely, respectively to each of 12 occlusal contact points of the crown.The maximum Mises stresses produced by oblique loading was observed near the connection interfaces of the abutment. The peak value was 430 MPa for SI3, 568 MPa for SI2 and 656 MPa for AI2 respectively. There was no significant difference in peak von Mises stress between models due to vertical loading. The maximum compressive stresses due to oblique load on the supporting bone adjacent to the implant were 145 MPa for SI3, 204 MPa for SI2 and 200 MPa for AI2, respectively.Internal joint type design of implant concentrated the stresses to the conical interface between fixture and abutment interface, demonstrating the wedge effect between them. Increasing the number of implants was the most effective contributing factor to reduce the stresses in the internal conical joint implant and supporting bone in our study models.
