The Morelli Light Stainless Steel .018″ Roth Brackets — Single Patient Kit is a complete 20-bracket set for one full case of fixed orthodontic treatment in the Roth prescription with an .018″ slot. It is supplied as Light Prescription Roth with hooks on canines (13th) and premolars, with torque, angulation and body length built into each bracket body.
Key Features
.018″ × .025″ slot — a smaller wire channel that works with lighter forces during alignment and levelling
Roth prescription, 13° canine version — +13° angulation on the upper canines (13/23) and -2° torque
Integrated hooks on canines and premolars — elastics and auxiliaries attach directly to the bracket, with no crimpable hooks on the archwire
Light line body — Morelli’s Light metal bracket line, with the body length specified per tooth position (2,3 mm to 3,2 mm)
Stainless steel construction — corrosion resistance and dimensional stability throughout treatment
Sandblasted base with anatomical curvature — mechanical retention for the adhesive and close adaptation to the enamel surface

Clinical Applications
Fixed orthodontic treatment in the Roth prescription on an .018″ slot set-up
Alignment and levelling with lighter forces, where the smaller slot limits the wire cross-section engaged
Canine retraction and space closure, anchoring elastic chain or coil on the integrated hooks
Which wires does an .018″ slot take?
The .018″ × .025″ slot engages a smaller wire cross-section, so it works with lighter forces during alignment. The bracket has to match the slot of the series already bonded, and the archwire sequence has to match the bracket.
