Since dentistry is a branch of medicine with its own peculiarities and very diverse areas of action, it can be considered as an interdisciplinary field. BIODENTAL ENGINEERING IV contains the full papers presented at the 4th International Conference on Biodental Engineering (BIODENTAL 2016, Vila Nova de Famalicao, Portugal, 21-23 June 2016), and covers the use of new techniques and technologies in dentistry. The contributions provide a comprehensive coverage of the state-of-the art in this area, and addresses the following topics: * Aesthetics * Bioengineering * Biomaterials * Biomechanical disorders * Biomedical devices * Computational bio- imaging and visualization * Computational methods * Dental medicine * Experimental mechanics * Signal processing and analysis * Implantology * Minimally invasive devices and techniques * Orthodontics * Prosthesis and orthosis * Simulation * Software development * Telemedicine * Tissue engineering * Virtual reality BIODENTAL ENGINEERING IV will be of interest to academics and professionals involved or interested in dentistry, biomechanical disorders, numerical simulation, orthodontics, implantology, aesthetics, dental medicine, medical devices and medical imaging.
