For final adjustment in tooth inclination (torque), the best wire choice is:

A Stainless steel wire

B Titanium molybdenum alloy

C Nitinol wire

D Gold wire

Solution

Correct Answer: Option B

Titanium molybdenum alloy (TMA) wires offer an optimal balance of flexibility and stiffness, making them ideal for precise torque control during the final tooth inclination adjustment. TMA provides a consistent, moderate force that allows effective root movement without risking excessive stress or unwanted tooth movement. Its excellent springback and formability enable customization of torque bends, essential for fine adjustments. Unlike stainless steel, TMA has superior biocompatibility and resilience to maintain the desired force level over time. This combination ensures efficient and controlled torque application, critical for final treatment stages.
