Retention Load of Telescopic Crowns with Different Taper Angles between Cobalt‐Chromium and Polyetheretherketone Made with Three Different Manufacturing Processes Examined by Pull‐Off Test

Abstract

Based on these results, telescopic crowns made of PEEK seem to show stable retention load values for each test sequence; however, data with thermo-mechanical aging are still required. In addition, further developments in CAD/CAM manufacturing of PEEK materials for telescopic crowns are warranted, especially for 0°.
