Description

Implant Laboratory Procedures: A Step-By-Step Guide provides its readers with a systematic and practical approach to the common dental laboratory procedures associated with implant restorative dentistry. Written with laboratory technicians and restorative dentists in mind, the book is organized by case type, taking common case scenarios and devoting a separate chapter to each one in turn, demonstrating each step of the laboratory procedure required for the implant restoration. Complications associated with the various prosthetic procedures are also included in each chapter and work orders are shown for each and every step. Cases are illustrated with products from various implant companies, but predominantly feature products from Biomet 3i.
