May’s Tip: IPR in Posterior Sextants-ARS Air-Rotor Slenderizing

By Dr. Adrian J. Palencar, MUDr, MAGD, IBO, FADI, FPFA, FICD

Air-Rotor Slenderizing is a protocol for creation of space by removal of precise amount of enamel between the teeth in the posterior sextants.  The crowns of the teeth in posterior region have approximately twice the thickness of the interproximal enamel on the anterior teeth. Thus, we can easily create 4 – 8 mm space per arch in the molar and premolar regions.  Maximum 0.5 mm of interproximal enamel should be removed per tooth.  It means creating total interproximal space not more than 1.0 mm.
