Effects of different types of temporary cements on the tensile strength and marginal adaptation of crowns on implants.

Purpose: The aim of this study was to evaluate the influence of four different types of temporary cements, Tempbond (Kerr), Tempbond NE (Kerr), Improv (Sterioss), and Dycal (Dentsply/Caulk), on the marginal adaptation and tensile strength of prosthetic specimens cemented on replicas of CeraOne abutments.

Materials And Methods: Four test groups were formed: Group 1 (G-1), Tempbond (Kerr); Group 2 (G-2), Tempbond NE (Kerr); Group 3 (G-3), Improv (Sterioss); Group 4 (G-4), Dycal (Dentsply/Caulk). For the specimens, gold cylinders (DCB 160, Nobel Biocare) adapted to stainless steel replicas of CeraOne abutments (Nobel Biocare) were utilized.
