Bioinert ceramics (zirconia, alumina) are used in medical devices in orthopedics and dentistry. Their surfaces may provide different functions: fixation of the device in the living tissue (e.g. dental implants), tribological role(joint substitutions),... In all cases the surfaces are treated to maximize their performance, but this modifications may entail negative consequences. The use of roughness to promote osseointegration of implants is a common practice, especially on dental implants. Roughening is often conducted by mechanical treatments, the most common being sandblasting. Therefore, chapter 2 focus on the implications of roughening by sandblasting on the mechanical behaviour of zirconia, alumina and a zirconia-alumina composite, and the differences between them. The work brought in chapter 3 was carried out entirely during a six-month secondment at CeramTec GmbH. In a bearing couple, lubrication mechanisms are complex and wettability and proteins play a yet-to understand role. The study compared the wettability of different materials, their ability to welcome protein adsorption and the effect of different cleaning procedures on wettability measurements and protein adsorption. Finally, the influence of the surface on cell activity is not driven exclusively by roughness: chemical modifications of the surface may enhance the perception of cells for the surface, and by careful tuning of the surface properties one may achieve a better integration without the downsides of roughness. In chapter 4, we explored a novel modification of zirconia, based on known techniques in chemistry, which introduces molecules with special functional groups capable of rendering the surface friendlier for cell adhesion, and opening the window for new exciting developments in the field of bioinert ceramics.

The biomaterials technology industry is already well established in the western world and is growing rapidly within Asian Pacific nations. It is often described as the ‘next electronics industry’, whilst the laser is described as a ‘solution looking for a problem’. This book describes the use of the laser to solve a troublesome and costly problem in a rapidly growing global industry. The authors have spent many years conducting research using laser materials processing and wettability characteristics and have perfected a technique to improve the bio-compatibility of various bone-implant materials using laser irradiation. They have made pioneering discoveries on the subject and established some generic theories and principals that will have a wide range of applications in the biomaterials field. Introduces inter-disciplinary research work covering laser materials processing and surface modification of biomaterials for enhanced compatibility. Includes highly scientific and novel research material. Serves both as a practitioner guide and a reference book. Covers an exciting and rapidly developing area of technology that is of keen interest to engineers and clinicians alike. Laser Surface Treatment of Bio-Implant Materials is rare in providing a reference source that describes specifically a mechanical engineering solution to a biotechnology problem. It serves as both a practitioner guide and a medium to high-level reference text book, and as such is a reference source for the engineer practising or looking to move into the biomaterials field, undergraduate and post graduate students and those conducting bio-related research in either academia or industry. It will prove useful to mechanical engineers, biotechnologists, biomechanical engineers, metallurgists, clinicians and even surgeons.
