| Outline of Final Research Achievements |
It can be concluded that the application of priming agents containing hydrophobic phosphate monomer (MDP) yielded the durable bond strengths of resin-based luting agents to a translucent zirconia material.The bond strength of a dual-polymerizing (UNI) resin-based luting agent to a translucent zirconia material was more stable in comparison with those of an auto-polymerizing (OPA) resin-based luting agent after thermocycling. In addtionly, the use of a silane (3-TMSPMA) enhances the bond strength of zirconia ceramics to lithium disilicate glass-ceramic material.Airborne-particle abrasionimproves the bond strebgth of CAD/CAM resin block to zirconia ceramics. Forthermore, the adhesively bonded veneering technique enhances fracture resistance of implant-supported zirconia-based prostheses veneered with a resin-based material.
