Fig. 1From: In vitro assessment of internal implant-abutment connections with different cone angles under static loading using synchrotron-based radiationSchematic figure of conical connection with a short mating zone (mating zone: orange circle) and butt-joint connection with a slightly angulated platform before (a) and after load application (b). The antirotational indices are encircled in green color. Red lines demonstrate lateral force transmission on the implant wall in conical connections and vertical distribution in butt-joint connections. Butt-joint connections with an adequate preload of the abutment screw distribute the force more vertically into the implant shoulderBack to article page
