A dental implant system having a first implant part, provided for introduction into a jawbone, and having a second implant part, provided for attaching a tooth replacement part, the implant parts being mechanically interconnectable via a connection pin which is integrally formed on one of the implant parts and which is insertable into a receiving duct provided in the other implant part, is to have a particularly high stability and long duration of use, even when ceramic materials are used for the implant parts. For this purpose, in a contact region to the receiving duct the connection pin is provided with a spacer formed of a material softer than the material of the connection pin, and the connection pin has a porous surface, in the surface region which is provided with the coating, to form a material fit connection to the coating.
