Research Abstract |
The improvement of bone formation-inducing activity for dental implant treatment and the newly developed adhesive for superstructure (crown, bridge, etc) were investigated. At 2 weeks after the implant surgery in rat tibia, the enhanced new bone formation was showed on the titanium surface treated with phosphorylated pullulan. The bone strength to Ag-Au-Pt-Cu alloys of 15-20% derivatized amino acid (cystine) containing urethane dimethacrylate polymers was 22.4MPa(SD:1.8),and the degradation of the bone strength was only 10% after thermal cycling with 20.000 cycles at 5-55℃.
