Abstract
A ceramic dental prosthesis including an implant for osseointegration in a jaw bone with a receiving opening and an abutment having a through-hole for receiving a bolt. The bolt is produced from a fiber-reinforced thermoplastic and connects the abutment and the implant. The dental prosthesis system includes an anti-rotation feature formed by a first interlocking means arranged on a proximal end of the abutment and a second interlocking means arranged on a distal end of the implant. The first interlocking means engages in the second interlocking means, wherein the first and second interlocking means are arranged at a distance from one another such that the abutment can be tilted relative to the implant. The bolt runs in the through-hole of the abutment and the receiving opening. An interference fit is provided between the bolt and the receiving opening of the implant.
