Roland Strietzel has created a new standard work for dental technology. Materials science specifies procedures for manufacturing processes. The author provides background knowledge on why certain processes should proceed in this way and not differently. In addition to a brief history, the respective material groups are defined and classified and their properties explained. The sequence of the treated material groups essentially follows the workflow of the dental technician. The meaning of the individual work steps and materials is explained. In addition to the conventional (analog) process, the (digital) CAD/CAM technology is also represented. Volume 1 deals with physical, chemical and biological properties and production processes. Volume 2 contains the material groups (impression materials, model materials, ceramic materials, implant.
