Abstract
Metal ion release from metallic materials, e.g. metallic alloys and pure metals, implanted into the human body in dental and orthopedic surgery is becoming a major cause for concern. This lecture provides an overview of both metallic alloys and pure metals used in implant materials in dental surgery. Additionally, a short section is dedicated to important biomaterials and their corrosive behavior in both real solutions and various types of media that model human biological fluids and tissues. The presentation gives an overview of analytical methods, techniques and different approaches applied to the measurement of in vivo, ex vivo trace metals released into body fluids and tissues from patients carrying metal dental implants. Reference levels of ion concentrations in body fluids and tissues that have been determined by a host of studies are presented in this lecture.
