The Morelli Self-Ligating Hybrid Stainless Steel .022 Roth Brackets — Single Patient Kit combines two ligation behaviors in one case: interactive brackets on the incisors and passive brackets on canines and premolars. The result is anterior torque control for a precise finish without giving up low-friction sliding in the posterior segments. Stainless steel, MIM manufactured, Roth prescription.
Key Features
Dual activation by arch position — interactive self-ligating brackets on the four incisors of each arch, passive self-ligating brackets on canines and premolars.
Anterior control, posterior freedom — the interactive clip engages the archwire on the incisors for torque expression, while the passive posteriors let the wire slide with minimal resistance.
Nitinol clip with elastic memory — the nickel-titanium alloy resists mechanical deformation throughout the entire treatment.
Anti-lock system — specially designed to prevent the clip from jamming due to plaque and tartar build-up.
Optimized slot — curvature relief and rounded edges reduce binding and notching for excellent sliding mechanics.
MIM-injected body with rounded design — a single highly precise, resistant piece with rounded contours for patient comfort.
High-retention base — mesiodistal and cervico-occlusal curvatures, micro pins, retention bands and sandblasting for maximum adhesive anchoring.

Clinical Applications
Cases requiring anterior torque expression while keeping posterior sliding mechanics efficient.
Finishing and detailing of the incisors, where interactive engagement improves control of inclination and rotation.
Full-arch fixed treatment under the Roth prescription, upper and lower, for a single patient.
Want low friction without losing anterior control?
Choose the Hybrid kit when the case demands torque expression on the incisors at the finishing stage. If the priority is minimum friction everywhere, choose the fully Passive kit; if the patient asks for a discreet treatment, choose the Ceramic kit.
