Abstract
Orthodontic appliances formed of a titanium alloy which substantially avoids toxic or allergic reactions in patients containing a .beta.-stabilizing element including at least 12 wt % molybdenum to produce a stable .beta.-monophase at body temperature are disclosed. The yield strength of the titanium alloy is within the range 1150 to 1450 MPa. The tensile strength of the titanium alloy is within the range 1350 to 1950 MPa. The elongation of the titanium alloy is within the range 10 to 14%. The titanium alloy may also contain about 5 wt % zirconium as another .beta.-stabilizing element. It may also contain about 3 wt % aluminum to improve age hardenability by strengthening the .alpha.-phase.
