This book shows computational finite element simulations to analyse the strength of implant anchorage for intrasinus and extramaxillary approaches under various occlusal loading locations and directions. Three-dimensional model of the craniofacial area surrounding the region of interest, soft tissue and framework are developed using computed tomography image datasets. The zygomatic and standard dental implants are modeled using a conventional computer-aided design software and placed at the appropriate location. Material properties are assigned appropriately for the cortical, cancellous bones and implants with Masseter forces applied at the zygomatic arch and occlusal loadings applied on the framework surface.

This book presents an analysis of the stress distribution and contact stresses in severe rheumatoid wrist after total wrist arthroplasty. It assesses and compares the load transfer throughout the joint and contact pressure at the articulations. The data obtained from this study is of importance as this provide greater evidence to the benefits of total wrist arthroplasty in rheumatoid arthritis patients.

Trauma Plating Systems is the first reference and systematic book in the topic of trauma plating system in view of biomechanical, material, biological, and clinical aspects. The effects of these aspects on effectiveness of trauma plating fixation are deeply reviewed, discussed, and challenged from which promising evaluation and development concepts are explored. This book is divided into five sections: Section I covers general concepts of biomechanical, material, biological, and clinical aspects. Then it provides fundamentals of trauma plating systems, principles of biomechanical evaluation methods, and biomechanics of plating fixation in Section II. Section III reviews current metallic materials with their advantages and disadvantages in plating fixation of bone fractures and new promising materials with their potential benefits to enhance the effectiveness of plating fixation. Section IV represents currently concerned biomechanical-clinical challenges of plating fixation for various bone fractures, and Section V presents current and new development concepts of this type of trauma implants. This book as an accessible and easy usable textbook for various disciplines of audiences who are dealing with trauma plating system and fixation such as orthopedic surgeons, trauma implant manufacturers, biomechanical researchers, biomaterial researchers, and all biomedical or medical students and residents in different levels of education. Author has been diligent in both engineering and research environments in terms of research, testing, analysis, validation, verification, clinical studies, and technical writing. His main interest and effort is to integrate biomechanical, material, biological, and clinical requirements of orthopedic implants for creation of novel design conception in this industry. He has developed the website http://orthoimplant-development.com/ for further communication in development of orthopedic implants.

This work identifies the characteristics of racket design parameters that influence racket performance. It presents the finite element analysis of several designs of badminton rackets and compares them to experimental results for validation. Designing a racket requires a comprehensive understanding of racket performance characteristics. Essentially, racket performance is related to the sweet spot, which is the spot on the racket head that produces the most power and control when it strikes a shuttlecock. Determining a coefficient of restitution can help to identify the sweet spot on a racket. By analyzing several head shape designs, it becomes apparent that isometric head shape rackets produce better coefficients of restitution compared to oval and round ones. It is recommended that the racket design consist of low string tension, stiffer racket shafts and bigger head size in order to produce higher shuttlecock speed.

This book develops and analyses computational wear simulations of the total ankle replacement for the stance phase of gait cycle. The emphasis is put on the relevant design parameters. The book presents a model consisting of three components; tibial, bearing and talar representing their physiological functions.

This book presents analyses of the most commonly reported failure modes of hip stems: loosening and thigh pain; both are attributed to the relative motion and instability at the bone-implant interface due to failure to achieve sufficient primary fixation. The book investigates various factors that could affect primary stability and therefore the long-term outcome of hip arthroplasty. The results complement experimental work carried out in this area as in-vitro experiments have several limitations that could be addressed through computer simulations.
