Orthodontic Beta TMA Molybdenum Wire

Titanium-Molybdenum alloy (Ti-Mo Alloy)wires were developed to have properties between stainless steel and Ni-Ti.

It is widely used as an orthodontic archwire for performing an orthodontic mechanotherapy.

When NITI wire, TMA wire,and austenitic stainless steel wire were compared, it was found that TMA.

Showed the greatest plastic strain and springback, followed by NITI and stainless steel.

The composition is: 79% Ti (Titanium), 11% Mo (Molybdenum), 6% Zr (Zirconium), and 4% Sn (Tin).
