 note = {application/pdf, Mechanical properties of titanium wires can be greatly influenced by the degree of working. When titanium wires formed under different degrees of working are fabricated into abutments or fixtures, the thus prepared implant system would be constructed with different types of titanium materials. Since such an implant system with different titanium materials might cause undesired fracture, this situation should be avoided. In this study, three commercially available titanium wires (i.e., CPT3 with 3mm in diameter, CPT4 with 4mm in diameter, CPT5 with 5mm in diameter) were evaluated for their mechanical properties such as tensile strength, elongation, yield strength, energy to break and hardness. The following conclusion is obtained: 1. For tensile strength, CPT4 showed the highest value, while CPT3 had the lowest value. 2. However, CPT3 showed the greatest elongation while CPT4 showed the lowest value, which was below the specification value. 3. The yield strength of CPT4 was the highest, while CPT3 had the lowest value. 4. CPT3 exhibited the highest value of energy to break, suggesting that CPT3 is superior in toughness. 5. Hardness of CPT3 had the lowest value, while there is no significant difference between CPT4 and CPT5. 6. Metallographic observation demonstrated twin structures in CPT4, indicating that a residual strain was involved in their microstructures. 7. Based on the above, material suppliers and manufacturers should be aware of these data, and they should be required to provide titanium materials with constant mechanical properties.},
