Fig. 2.

The diagram shows the different parameters measured on the digital images and radiographs as well as the three defined zones of the prosthesis: side (I), chamfer (II), and dome (III). Cement penetration depth was measured perpendicular to the implant (A), cement mantle height was measured at the dome (B), and cement mantle thickness was measured at the side (C). Cement penetration was calculated as a percentage of bone interdigitated by cement to the total area of bone under the implant. The mean depths of penetration were also measured for each zone by averaging the depth of penetration at 1-mm intervals.
