Summary

Textbook of Dental Technology is a major new resource for undergraduate dental students and trainee dental technicians.Employing a task-based approach, the book offers step-by-step guidance to the current techniques and materials used in dental technology. As well as providing thorough instruction as to core competencies in impression handling, model production, tray construction, articulators and facebows, the book introduces the reader to the basics of more specific and/or specialist areas of practice, such as complete and partial denture prosthetics, fixed prosthodontics, orthodontic work, maxillo-facial technology, occlusion and implants.The book also provides an excellent ready reference to instruments, equipment and key terms as well as advice on establishing effective communication within the dental team and study tips.
