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.
This book creates the theoretical foundation that novices need to perform the finite element method in implant dentistry. It shows how both the implant dentist and the designer can benefit from finite element analysis. The authors explain the theory and math of the finite element method. Then, you get practical applications alongside discussions of the critical issues in using finite element analysis for dental implant design.
This collection provides researchers and scientists with advanced analyses and materials design techniques in Biomaterials and presents mechanical studies of biological structures. In 16 contributions well known experts present their research on Stress and Strain Analysis, Material Properties, Fluid and Gas mechanics and they show related problems.
This book is intended for those dentists and dental technicians who wish to make prostheses specifically for implant support. The methods and materials necessary for making frameworks which fit accurately without corrective soldering form the basis of this innovative book. Here is a unique blend of research data and practical know-how with the objective of providing a dental technology as predictably reliable as the osseointegrated implants to which it is connected.
The maintenance of the osseointegrated implant bone interface is critical to the success of the osseointegrated implant. Many clinical studies have suggested that repeatedly excessive loads applied to the implant restoration, is one of the factors contributing to breakdown at the implant/bone interface and premature failures of the osseointegrated implant. In the single unit osseointegrated implant in the posterior mandible the mesiodistal and buccolingual widths of the crown are generally greater than the width of the implant fixture. The point of load application is one of the variables that influences the manner in which occlusal forces are transmitted to the implant and surrounding bone. Off axis loads applied to the crown create a cantilever effect and introduce bending moments which may cause excessive stresses at the implant bone interface. The wider the crown, the greater the potential for off axis loading. The purpose of this study was to evaluate and compare the effect of axial and off axis loads on the stress gradients at the oxxeointegrated implant/bone interface of a single unit posterior implant. Finite element analysis was used to evaluate the magnitude and location of stresses. Occlusal forces were modeled as axial and off axis vertical loading. The study showed that under load conditions the highest stresses were concentrated at the apex of the implant and at the crestal bone/implant interface. Off axis loading resulted in a large increase in compressive stresses in the crestal cortical bone on the side of the applied load, and a large increase in tensile stresses in the crestal cortical bone on the side opposite the applied load.
