DENTAL IMPLANT OR ABUTMENT COMPRISING A CERAMIC BODY COVERED WITH A MONOMOLECULAR PHOSPHATE LAYER

摘要

The present invention refers to a dental implant or abutment including a ceramic body having a surface, the ceramic body including zirconia as the main component. At least a first surface area of the ceramic body is covered with an at least essentially monomolecular phosphate layer having a thickness of less than 1.0 nm. The phosphate layer contains phosphates selected from the group consisting of ortho-phosphate, poly-phosphates, cyclo-phosphates, and mixtures thereof. Furthermore, a kit including a gas- and liquid-tight container, with the dental implant or abutment being stored inside the container, and a method for the preparation of the dental implant or abutment are disclosed.
