Abstract
An implant, in particular an intervertebral endoprosthesis, with a connection plate (3) which is to be fixed so as to bear on a bone surface and which is to be applied to the bone surface in a direction of application running transverse to its main extension. For protection against a shearing force running parallel to its main extension, the connection plate (3) has teeth (6) projecting in the direction of application. These teeth (6) are delimited by surfaces (11, 12, 13) which include a main surface (11) arranged in the direction of application and transverse to the direction of shearing. Two teeth or groups of teeth in each case lie opposite one another in the direction of shearing and point in opposite directions.
