Abstract: A dental implant made of a ceramic material including an implant surface having at least partially a contact angle of less than 20°, the implant surface being at least partially covered by a protective layer. The protective layer includes a dextran having a molecular weight of more than 15,000 Da.

Abstract: A process for the preparation of a sterilized ceramic body including or essentially consisting of stabilized zirconia of a defined colour, including the steps of: providing a ceramic primary body including or essentially consisting of stabilized zirconia of a first colour A, and sterilizing the primary body using radiation sterilization whereby the primary body undergoes a colour change to a colour B. The process includes the further step of irradiating the sterilized primary body with electromagnetic radiation of at least one wavelength lying in the wavelength band ranging from 150 nm to 700 nm to induce an at least partial reversal of the colour change to obtain a colour C of the sterilized ceramic body, the colour C complying with the following requirements in the CIELAB colour space: L* being from 54 to 95, a* being from −15 to 15 and b* being from −15 to 15.
