Purpose: To evaluate CAD/CAM conic crowns to obtain a reversible and predictable retention in implant-supported prostheses.
Materials And Methods: Five 1- to 8-degree CAD/CAM abutments and their respective copings (n = 40) were designed and manufactured to measure the retention strength (in N) on a Zwick/Roell testing frame.
Results: The mean retention strength values found, in descending order of cone angle, were as follows: 8 degrees, 21.
