We received a request from an orthodontic lab to manufacture our Flatbows without the loop, so that their technicians could make the size loop required for a certain prescription from their orthodontist.
Our "Loopless" Flatbow Labial Arches are manufactured using .032 diameter, 304V, bright, 3/4 hard stainless steel, medical grade wire.
Across the anterior section of the archwire, the wire is flattened, providing stability and patient comfort. The posterior region of the flatbow is round to allow anchoring to the orthdontic appliance.
NOTE: This flatbow has no loops as shown in the image, but does have the flattened anterior section.
We also have the original Flatbows with loops.
