Process for providing a topography to the surface of a dental implant

A process for providing a topography to the surface of a dental implant, the surface being made of a ceramic material having yttria-stabilized zirconia, the process including: providing a macroscopic roughness to the surface of the dental implant by a mechanical process and/or injection molding tech...

Beschreibung
Zusammenfassung:	A process for providing a topography to the surface of a dental implant, the surface being made of a ceramic material having yttria-stabilized zirconia, the process including: providing a macroscopic roughness to the surface of the dental implant by a mechanical process and/or injection molding technique; and etching at least a part of the roughened surface, wherein etching is carried out using an etching solution having hydrofluoric acid at a temperature of 70° C. at least, such that discrete grains or agglomerates of grains are removed from the yttria-stabilized zirconia, thereby forming recesses and cavities in the roughened surface is disclosed.
