In vitro bond strength of silica-coated metal posts in roots of teeth.
This study determined the in-vitro bond strength of abrasive-sprayed and silica-coated Ni-Cr-Be posts to roots of extracted teeth using three resin cements (Panavia EX [P], Super-Bond C&B [SB], Prisma Universal Bond 2-Dicor [PUB-D]) and zinc phosphate cement (ZP). There were no significant differences among bond strengths of resin cements (8.8 to 10.8 MPa) bonded to abrasive-sprayed posts, but the bonds were stronger than those obtained using zinc phosphate cement (4.4 MPa). With the silica-coated posts, Super-Bond C&B produced the highest bond strength (14.5 MPa), followed by PUB-D (10.9 MPa), P (7.5 MPa), and ZP (5.4 MPa).
