The Morelli Self-Ligating Interactive Ceramic .022 Roth Brackets Single Patient Kit is a complete single-patient set of aesthetic self-ligating brackets in the Roth prescription. The interactive clip behaves passively on light round archwires and engages actively as wire dimension increases, so the same appliance delivers low-friction alignment early and full torque expression at finishing.
Key Features
Interactive clip mechanism — the clip clears the slot on light round wires for free sliding, then contacts larger rectangular wires to express the built-in torque during finishing
Interactive across the whole arch — every ceramic position in the kit, upper and lower, is an interactive piece, so clip behaviour is consistent from incisors to premolars
Alumina ceramic body — translucent, color-stable ceramic with a matte surface that blends with enamel and resists staining through long treatments
Nitinol clip — superelastic nickel-titanium clip with a simple open-and-close mechanism, operated chairside without separate instruments
Anti-Lock System — Morelli’s clip system, specially designed to prevent the clip from jamming due to plaque and tartar buildup, so it keeps opening and closing smoothly throughout the whole treatment
Bi-blasted and silanized base — treated bonding base for reliable adhesion and controlled debonding
Low-profile design — reduced bracket height and rounded contours for patient comfort and soft-tissue tolerance
Hooks on canines and premolars — integrated hooks on the canine and premolar positions for elastics and auxiliaries

Clinical Applications
Comprehensive Roth treatment requiring active torque delivery in the finishing stage, where the clip must engage the rectangular archwire rather than simply retain it
Aesthetic cases in adults who want ceramic brackets without giving up the torque control of a conventional ligated appliance
Alignment and levelling with light forces in the initial phase, where the clip stays clear of round wires and lets them slide freely
Do you need low friction at the start and real torque expression at the end?
Choose the interactive version when the case depends on finishing torque — the passive kit will not engage the wire, and the hybrid kit only places interactive pieces on the incisors.
