The Morelli Full Self-Ligating Archwires Single Patient Kit holds the complete archwire sequence for one case treated with self-ligating brackets. It combines Superelastic NiTi, Thermo-Plus NiTi, CrNi and TMA wires in 10 different pairs — 20 archwires in total — ordered from the lightest round wire through to the rectangular finishing wires.
Key Features
Ten paired sizes — each size in the kit is supplied as one upper and one lower archwire, for 20 wires in total.
Four alloys in one sequence — Superelastic NiTi and Thermo-Plus NiTi, thermally activated above 27 °C (80.6 °F), for alignment and leveling, CrNi for stabilization and TMA for finishing.
Round to rectangular progression — the round wires align and level without expressing torque; the rectangular wires fill the slot and take over third-order control.
Matched to self-ligating systems — the sequence and force levels are selected for low-friction, clip-retained brackets.
Single-patient organization — one kit covers one case from start to finish, simplifying chairside handling and stock control.
Instructional packaging — the box itself is a booklet describing each archwire in the sequence and its respective forces.

Package Includes: 20 archwires — 10 different pairs, each pair with one upper and one lower wire: Superelastic NiTi Ø.010″; Thermo-Plus NiTi Ø.012″, Ø.014″, Ø.016″, .016″ × .016″, .016″ × .022″, .017″ × .025″ and .021″ × .025″; CrNi .019″ × .025″; TMA .017″ × .025″
Clinical Applications
Full-case treatment with self-ligating brackets, from initial alignment through to finishing, using a single kit per patient.
Sequential archwire exchange at each appointment, following the round-to-rectangular progression built into the kit.
Crowding, rotation, deep bite, open bite, crossbite and diastema cases that require a complete wire progression rather than isolated sizes.
Why choose the Morelli full self-ligating kit?
Because it puts an entire patient’s archwire sequence in one box — four alloys, ten paired sizes, upper and lower — removing guesswork from wire selection and keeping stock control simple.
