Dentistry is a branch of medicine with its own peculiarities and very diverse areas of action, which means that it can be considered as an interdisciplinary field. Currently the use of new techniques and technologies receives much attention. Biodental Engineering III contains contributions from 13 countries, which were presented at BIODENTAL 2014, the 3rd International Conference on Biodental Engineering (Póvoa do Varzim, Portugal, 22-23 June 2014). They provide a comprehensive coverage of the state-of-the art in this area, and address issues on a wide range of 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 III will be of interest to academics and others interested and/or involved in biodental engineering.
