This book provides surgeons with important insights into laser technologies as well as a sound understanding of their current and potential applications within oral and maxillofacial surgery and related disciplines. The opening chapters focus on the relevant physical background, the technology of the typically used lasers, laser–tissue interactions, and the treatment systems. Detailed information is then provided on the various established applications of laser treatments, including in relation to skin and mucosa and the dental hard tissues and bone. Special applications are also described, for example with respect to periodontal surgery, peri-implantitis therapy, photodynamic treatment, holography and additive manufacturing. The book closes by examining technologies that will soon be available for application in hospitals, topics which are currently the subject of research, and laser safety. Beyond surgeons, the book will be of value for engineers and scientists working in the field of medical engineering using lasers.
