 note = {application/pdf, Commercially available titanium materials are classified on a standard scale form 1 to 4. The standard is based on the amount of Oxygen, Nitrogen, and Iron contained in the titanium. Recently, implant material made of type 4 titanium, has been marketed. This study compares several mechanical properties including tensile strength, elongation, yield strength, energy to break and hardness between type 2 and type 4. The followings conclusions were obtained: The tensile strength, yield strength, and energy to break of type 4 are higher than those of type 2. Elongation of type 4 is less than that of type 2. Hardness of type 2 is than that of type 4. Overall evaluations of mechanical properties indicate that pure titanium type 4 is superior to type 2 as an implant material.},
