Abstract
The invention relates to an angled abutment for a dental-prosthetic arrangement, in which the abutment is divided into a first sub-component and a second sub-component, wherein the first sub-component can be fixed by means of a fixing screw to an implant and has a tool opening through which a tool is able to engage to reach the screw head of the fixing screw. After the first sub-component has been fixed to an implant, the second sub-component can be connected to the first sub-component, preferably via a screwed connection, and at the same time completely covers the tool opening of the first sub-component. A retaining structure facing away from the first sub-component is formed on the second sub-component and interacts with a counter-retaining structure on a prosthesis to provide a releasable connection, which can be produced without tools, between the abutment and the prosthesis.
