Interproximal Reduction: A Twin Helix Device

Abstract

Introduction: Interproximal enamel reduction dates back to 1944 when it was first advocated for correcting lack of tooth size harmony by stripping the proximal surfaces of the mandibular anterior segment. Despite convincing results, interproximal reduction (IPR) only became popular after the advent of bonding, as full-arch banding done previously completely deferred the use of this method for tooth material reduction. With the current status and ongoing development of new techniques of IPR, use of this method as a mean of gaining space has increased exponentially over the last three decades.Procedure: A 12-inch length of 0.036" diameter wire is used for fabrication of the assembly. Helices of 2.5 mm diameter with two coils and the other according to finger grip are fabricated, and U-loops are prepared at the free ends for engaging the proximal strips. This assembly can be placed intraorally in the interdental region of our choice to cut the tooth material. Conclusion:This assembly provides an effective grip rather than using hand held strips. It is also accessible in both anterior and posterior regions with a minimum requirement of armamentarium and can be sterilized and reused.
