Claim 0:
1. A dental prosthesis system with a mechanical weakness, for the use with at least two dental implants, comprising:
a first prosthetic part, with a mesial, distal, lingual and buccal faces, a top section and a bottom section;
a second prosthetic part, with a mesial, distal, lingual and buccal faces, a top section and a bottom section;
a sacrificial prosthetic screw, joining the first prosthetic part and the second prosthetic part, and configured to deform or fracture in the event of excess load due to mastication force or fatigue use;
at least two screw channels leading to at least two connectors arranged in the bottom section of the first prosthetic part, wherein the at least two screw channels are configured to introduce implant screws; and
an engaging and guiding system comprising two female elements disposed on the top section of the first prosthetic part, and two corresponding male elements disposed on the bottom section of the second prosthetic part, wherein the two female elements and the two corresponding male elements are releasably connected, wherein the first prosthetic part is connected to at least two dental implants through the at least two connectors,
wherein the mechanical weakness is provided by the sacrificial prosthetic screw.
