Abstract
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.
The following results were obtained:
1. Regarding blast treatment pressure, the tensile shear strength was highest at 0.4 MPa.
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.
