Effect of surface modifications on the retention of cement-retained implant crowns under fatigue loads: An In vitro study

open access: yesJournal of Pharmacy and Bioallied Sciences, 2017
Background: Masticatory forces cause fatigue to the dental luting agents, adversely affecting the retention of these cement-retained crowns. Sandblasting (SB) and diamond abrading the abutment surface improves the bond strength of luting agents. However,
