Digitalized dentistry enables efficient, fast and precise and error free production of fixed prosthodontics appliances. The term 'Digitization' refers to conversion of an image or signal into digital code by scanning, tracing, or a graphics tablet or using an analogue to digital conversion device. There is endless scope of digitalisation and technology in prosthodontics, be it in the clinical and lab procedures like use of CAD-CAM technology, stereolithograph, rapid prototyping, use of virtual articulators and digital facebows, digital radiographs or in the field of training, education and research by the use of virtual patient programs, dental softwares, optoelectronic recording of jaw motion, digital instron machine, retention testing device, audiovisual aids the list will remain endless. The advantages of the digital impressions and scanning systems are improving patient acceptance, reducing the distortion of impression materials, 3D pre-visualization of tooth preparations, and potential cost- and time-effectiveness. Therefore, Digitization has become part and parcel of the Contemporary Prosthodontics with the probability of most procedures being based on the Digitization.

The discipline of biomedical engineering, which applies engineering principles to living system, has unfolded a new era in diagnosis, treatment planning and rehabilitation in patient care. One aspect of this field, biomechanics comprises of all kinds of interactions between tissues and organs of the body and the forces acting on them. Advancements in prosthetic, implant, and instrumentation design have been realized because of mechanical design optimization theory and practice. In many instances biomechanics can literally make (or) break an implant case. Usually, in any structure subjected to functional loads, there may be situations leading to overload and subsequent complications. Biomechanics is critical in dental implant design. The objective of this book is to summarize knowledge about the biomechanics of dental implants to help a clinician confront the following questions: Why are there so many different implant biomaterials and shapes? Should implants have special coatings on the surface, and if so why? Should an implant have some sort of built-in shock absorber? The goal is to give the clinician perception into the design process and biomechanical aspects of implant design.
