The Morelli TwistForm Stainless Steel Braided Lingual Retainer is a three-wire braided CrNi (nickel-chromium) wire supplied in 41.5 mm sticks for bonded 3x3 lingual retention. It is offered in two external diameters, .020" (ร 0.50 mm) and .026" (ร 0.65 mm), so the retention wire can be matched to the case, and the braided section adapts to the curvature of the lingual arch for a low-profile bonded retainer.
Key Features
Three-wire braided construction โ three CrNi wires braided into a single retention strand.
Two external diameters โ ร 0.50 mm (.020") and ร 0.65 mm (.026").
41.5 mm sticks โ pre-cut length intended for canine-to-canine (3x3) retention and trimmed chairside to the arch.
