Interproximal Reduction (IPR): A Complete Guide to Tooth Slimming & Orthodontic Benefits 🦷

Interproximal reduction (IPR) (also called interproximal enamel reduction (IER) / slendering, air rotor stripping (ARS) or reproximation) is the practice of mechanically removing enamel from between the teeth to achieve orthodontic ends, such as to correct crowding, or reshape the contact area between neighboring teeth.[1] After reducing the enamel, the procedure should also involve anatomic re-contouring and the protection of interproximal enamel surfaces.[2
