抄録

To achieve the long-term function of superstructures inserted in titanium implants without causing dislodgement, it is necessary to maximize their adhesive strength. It is known that sand-blast treatment markedly influences the adhesive strength. Therefore, to improve the adhesive strength using sand-blast treatment of titanium materials, we evaluated the influence of blast pressure, and effects of applying blast powder coated by adhesives (Super-Bond C&B), based on tensile and compressive shear strengths.<br/> The following results were obtained:<br/> 1. Regarding blast treatment pressure, the tensile shear strength was highest at 0.4 MPa.<br/> 2. When blast treatment was performed using alumina powder coated with adhesives, the compressive shear strength increased by approximately 13%. We considered that this was because the adhesives coated on the alumina powder remained on the surface of the titanium.
