The Morelli Titanium Molybdenum Straight Lengths are beta-titanium (TMA) orthodontic wires supplied as pre-cut straight sticks in round and rectangular cross-sections. The titanium-molybdenum alloy delivers lighter, more continuous force than stainless steel of the same cross-section, while remaining formable and weldable at the chairside.
Key Features
Beta-titanium alloy — delivers a lighter, more continuous force than stainless steel of the same cross-section, for physiologic tooth movement.
Weldable without solder — joints can be welded directly to the wire while preserving its mechanical properties.
Excellent formability — accepts loops, offsets and compensating bends without fracturing, so springs can be built at the chairside.
High elasticity and springback — maintains force over a long activation range, reducing the number of reactivation visits.
Shape memory characteristics — the alloy returns toward its formed shape after deflection.
Round and rectangular sections — the same alloy covers alignment, torque control and finishing stages.
Corrosion resistant and biocompatible — smooth surface finish with high wear resistance for extended intraoral service.

Clinical Applications
Finishing and detailing — final settling and individual tooth positioning where a lighter, continuous force is preferred over stainless steel.
Torque control and root positioning — rectangular sections engage the bracket slot to express third-order correction with reduced force levels.
Auxiliary springs and sectional mechanics — bent and welded at the chairside for intrusion arches, uprighting springs and cantilever segments.
What sets TMA apart from stainless steel?
It combines light, continuous force with chairside formability and weldability, giving the clinician one alloy for the springs, sectionals and finishing wires that stainless steel cannot deliver.
