INTENSIV's Ortho-Strips System strips are diamond-coated instruments designed to be mounted on a dedicated oscillating handpiece, for controlled interproximal enamel reduction (IPR) as part of orthodontic treatment. Their double-sided diamond coating allows both adjacent proximal surfaces to be treated simultaneously in a single pass, unlike a single-sided strip that would require insertion from each side separately. The oscillating motion, gentler than continuous rotary action, limits heat build-up and the risk of grooving the enamel, resulting in a smoother final surface. Sold in a box of 3, sterilizable, these strips fit into the interdental space-gaining sequence without extraction, alongside a set of grits of varying fineness depending on the treatment stage.
