| Abstract Scope |
Due to their low mechanical strength, the ASTM Ti G2 and Ti G4 have limitations for biomedical applications. The ASTM F136 (Ti G5) releases toxic ions. This work aimed to compare the mechanical and clinical properties of Ti G4 nanostructured after ECAP with those of Ti G2, Ti G4, and Ti G5. Bars, disks, and dental implants were tested. Mechanical tests (tension, compression, hardness, elastic modulus, fatigue, and torque) and roughness measurements were performed. The mechanical test results showed that Ti G4 ECAP has a higher mechanical strength than Ti G2, Ti G4, and Ti G5. After acid-etching treatment, Ti G4 ECAP has better surface morphological features than Ti G2, Ti G4, and Ti G5. The clinical performances of Ti G4 and ECAP Ti G4 were similar. The ECAP Ti G4 dental implants have adequate mechanical properties for biomedical applications with the advantage of not releasing toxic ions. |
