摘要: Abstract Objective: The purpose of this study was to compare the shear-bond strengths (SBSs) an acrylic resin and a cobalt-chromium (Co-Cr) alloy after applying metal primer, Nd:YAG laser irradiation, or both sandblasted surface Co-Cr alloy. Background Data: serviceability removable partial denture (RPD) is dependent on bond strength at resin–alloy interface. No previously published studies exist use lasers for preparing in RPD obtain high-strength between PMMA Methods: One-hundred twenty specimens were randomly assigned four equal groups: Group I, sandblasting; II, sandblasting + metal primer; III, sandblasting + Nd:YAG laser; IV, laser + metal primer. To establish most appropriate fluence modifying cast specimens, we conducted preliminary study. irradiation fluenc...
