As an ideal dental material and consideration of electrochemistry, titanium employed both as an implant and a prosthesis will have good results. Using titanium, this study was conducted to investigate the relationship between bonding strength of dental adhesives and surface roughness and thermal cycling. The results were as follows:
1. Zinc phosphate cement did not adhere to titanium plate.
2. The bond of polycarboxylate cement and Panavia 21 to the titanium was strong.
3. Polycarboxylate cement shrank when it was heated, while Panavia 21 cement expanded.
4. Polycarboxylate cement showed a tendency to decrease in adhesive strength to titanium plate after thermal cycling.
5. Panavia 21 showed considerable decrease in adhesive strength to titanium plate after thermal cycling.
6. The adhesive strength of zinc phosphate cement was influenced by the roughness of the titanium surface.
