Abstract: A process for the preparation of a topography for improved fibrin network formation and cell mineralization on at least a portion of a dental implant made of a binary titanium-zirconium alloy, the portion being destined to be embedded in a patient's jawbone and to be in contact with the jawbone via a bone-contacting surface, the process includes the subsequent steps of a) subjecting the bone-contacting surface of the dental implant to a sandblasting treatment, b) etching the sandblasted bone-contacting surface, and c) treating the sandblasted and etched bone-contacting surface with water or an aqueous solution for a duration of more than two days, during which nanostructures continuously grow on the bone-contacting surface, the nanostructures extending in at least two dimensions to 200 nm at most. The process is characterized in that the treatment of b) is carried out at a temperature from 40° C. to 60° C.

Abstract: A method of surface treating a drill, the drill including a shaft extending along a central longitudinal axis from a proximal end to a distal end, the proximal end of the shaft including a shank adapted for connection to a rotary driver, the shaft further including, distal of the shank, a fluted section including at least one flute extending along the longitudinal length of the fluted section, the method including the steps of: acid etching at least a portion of the fluted section of the shaft in order to create a visible matted effect, subsequently electro-polishing at least the portion of the fluted section of the shaft in order to visibly reduce the matted effect and subsequently creating one or more visual marking within the portion of the fluted section of the shaft.

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.

Abstract: A process for providing a sterilized dental article, at least a portion of the surface of which exhibiting a contact angle of less than 45°. The process includes the subsequent steps of a) providing a dental article and b) subjecting the initial dental article to a hydrogen peroxide plasma treatment. It is characterized in that the hydrogen peroxide plasma sterilization treatment of step b) is carried out in the presence of a carbon-containing compound, which during treatment is converted to form a carboxylic group attached to the surface of the dental article.
