Book excerpt: Abstract : Development of an ideal substitute for missing teeth has been a major aim of dental practitioners for millennia. Modern dental implants are biocompatible screw-like titanium {u2018}fixtures{u2019} that are surgically placed into the jaws to replace missing teeth. Implants are superior to conventional prostheses, in both function and long-term predictability. In 2006 approximately 30,000 implants were placed in Australian patients. Implant sales have doubled in the last 5 years and are increasing by about 15% per year. Although implants exhibit excellent long-term retention (~95% after 5 years), there are significantly more failures in areas where bone quality and quantity is poor, resulting in poor patient outcomes and costs estimated at $15 million per year in Australia. Most failures arise from poor clinical technique and inadequate understanding of the potentially damaging stress characteristics during implant placement and function (chewing). Three-dimensional (3D) Finite Element Analysis (FEA) is a numerical method for analysing stresses and deformations in structures of any given geometry and under any load. There are reports on utilising 3D FEA to investigate implant-jawbone interactions after full osseointegration. However no work has been done to comprehensively quantify the performance of the bone-implant system during and after implantation. This research thus aims to develop a comprehensive FEA technique to evaluate the performance of the bone-implant system during the implantation process itself, as well as the healing and maintenance phases of osseointegration.

Book Synopsis Finite Element Analysis of and Multiscale Skeletal Tissue Mechanics Concerning a Single Dental Implant Site by : Timothy James Sego
Download or read book Finite Element Analysis of and Multiscale Skeletal Tissue Mechanics Concerning a Single Dental Implant Site written by Timothy James Sego and published by . This book was released on 2016 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finite element analysis (FEA) in implantology is performed in design applications concerning the complex topology of an implant, according to theoretical assumptions about and clinical data concerning the biomechanical nature of skeletal tissue. Implants are placed in topologically and physiologically complex sites, and major disagreement exists in literature about various aspects concerning their modeling and analysis. Current research seeks to improve the implementation of an implant by the use of short implants, which negate the necessity of additional surgical procedures in regions of limited bone height. However, short implants with large crown heights introduce biomechanical complications associated with increased stress and strain distributions in skeletal tissue, which may cause bone loss and implant failure. The short implant is characterized by the geometric ratio of the crown height to the implant length, called the crown-to-implant (C/I) ratio. In this work nonlinear FEA was performed to investigate the effects and significance of the C/I ratio on long-term implant stability. A finite element model was developed according to literature, and emulation of previous research and comparison of reported results were performed. Comparison of results demonstrated significant sources of error in previous research, which are argued to be caused by mesh-dependency from common model idealizations in literature. A convergence test was then performed, which verified the mesh-dependency of results and challenged the reliability of some common model assumptions and methods of analysis in literature. A 16-point design of experiments was then performed to evaluate the significance and influence of the C/I ratio, considering a proposed novel method for evaluating results and predicting long-term stability. Analysis of results demonstrated that the C/I ratio augments the inherent biomechanical effects of an implant design, particularly overloading strain concentrations at implant interface features. The use of short implants with high C/I ratios is determined to be inadvisable, considering the physiological response of tissue to strain distributions and biological context. A novel, multiscale material model is then proposed to describe the short-term accumulation of damage and biomechanical remodeling response in orthotropic skeletal tissue, as a potential solution to the mesh-dependency of results.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Stresses and strain in the bone surrounding a dental implant are of interest regarding the study of bone healing following the dental implantation procedure. Techniques for mapping strain in bone have been developed for physical experimentation, but computational methods for finding these strain maps are more desirable for their flexibility in dealing with changing physical properties, loading conditions, and geometries.This project first aims to develop a finite element model of a surgical dental implant and two adjacent teeth. Two implants from a cadaver are scanned by a micro-CT scanner and those images are used to create two models. The first is an implant for tooth 23 and the second for tooth 26. After building the model, the implant is loaded with a pressure and the resultant stress and strain in the teeth and surrounding bone are calculated using the finite element method. The effects of element size are studied. Various boundary conditions are explored. The parameters of the model are then modified to simulate various conditions including differences in the stiffness of the cortical bone, the teeth dentin, and the titanium implant. These differences in material properties arise from an interval of stiffness values in the literature for bone and teeth, and the unknown composition of the implant.The computational model is compared to a physical experiment during which the same implants were loaded by a downward force of 100 N. In the experiment, the implant-tooth complexes were scanned again after loading, and digital volume correlation methods were measured to calculate the strain [1]. The goal for this project is to evaluate the finite element method as a means for studying the mechanical effects of loaded implants in the surrounding bone. The methods developed in this project might be used in future studies of implant-bone complexes.
Book Synopsis In Search of an Improved Methodology for Measuring Dental Implant Stability by : Naseeba Khouja

This book was released on 2017 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the importance of the need for measuring dental implant stability, an effective, reliable methodology has eluded researchers, with current methods used to detect implant stability either in the early stages or incapable of providing a complete picture. This study sought to identify a parameter capable of measuring dental implant stability, to allow for the successful detection of failing implants. Through the combined use of experimental modal analysis (EMA) and finite element analysis (FEA), we examined the accuracy and reliability of three implant stability devices--the Osstell ISQ®, the Periotest®, and the Periometer--by calibrating them via both EMA and FEA, using models of dental implants of various lengths in Sawbones® of different densities. The theoretical mechanics used to operate the three devices were analyzed to understand their assumptions and limitations. To estimate angular stiffness, we employed implant models of various lengths and widths in Sawbones® of different densities. To gauge how effectively Sawbones® and porcine bones could represent human bones, different types of bone models (i.e., porcine bone, human mandibular bone, and Sawbones®) were compared using the Osstell ISQ® and the Periotest® devices, and EMA, in addition to measuring apparent bone density. Micro-computed tomography (micro-CT) was used to estimate bone mineral density (BMD) and morphometric parameters of both porcine and human bone samples. After demonstrating that the three above-mentioned devices were deficient both theoretically and experimentally, we developed an optimal model for implant stability testing through the combined use of EMA and FEA. Natural frequency, although a robust and consistent measurement, does not equate with dental implant stability. Porcine bone may overestimate implant stability measurements when applied to human bones. Sawbones® may provide reasonably good models but should be used with caution. Boundary conditions and experimental setup play an important role in the outcome of research and should be taken into consideration. The angular stiffness coefficient--which is independent of the type of abutment used--was found to represent a superior index for quantification of dental implant stability, successfully differentiating stability of implants of both varying lengths and diameters, while the other methods tested did not.
