Ceramic materials in implant dentistry: Overview
Introduction. The roots of the term "ceramic" can be traced back to the Greek word "keramos", meaning "pottery". Keramos in turn is derived from a Sanskrit origin, meaning "to burn". Thus, it may be reasoned that a ceramic material is a substance that is tempered through burning or heat-treating. A more scientific definition of ...
