Abstract
Durable adhesion between resin composite cement and Ti prostheses is critical for a long clinical life in dentistry. A rough surface is a prerequisite for mechanical interlocking and a special coating method, silica-coating must be followed by silanation for chemical adhesion. Commercially pure grade-2 Ti specimens were modified by silica-coating and silanized with an experimental silane blend primer or two commercially available silane primers. Specimens were assigned randomly: Group-A (control; polished only Ti), Group-B (polished Ti + silica-coating + primers), Group-C (polished Ti + etching with HNO 3 + with or without primers), Group-D (polished Ti + silica-coating + etching with HNO 3 + with or without primers), Group-E (polished Ti + etching with HCl+H 3PO 4 + with or without primers), and Group-F (polished Ti + silica-coating + etching with HCl+H 3PO 4 + with or without primers). Next, Ti specimens were analyzed for their atomic concentration by electron dispersive spectroscopy (EDX). BisCem™ resin cement was used to build up enclosed mold stubs onto the Ti specimens. Enclosed mold micro-shear bond strength (EM-µSBS) was measured after storage in distilled water for 1 day, 1 week, 4 weeks, and 8 weeks. A combined treatment employing silica-coating + the blend HCl+H 3PO 4had a more substantial effect on Ti surface roughness when compared to other surface pretreatments. Whereas, the highest EM-µSBS values were observed in Group-D from week 1 to week 8. A novel combined dual surface modification creates higher surface roughness on Ti, and this might significantly improve the durability of resin-Ti adhesion.
