October’s Tip: Mulligan Mechanics Part IV Mulligan Intrusion Arch

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

After the .018 SS arch wire is measured and cut, it should be inserted into the maxillary or mandibular tubes, to evaluate the parallelism and the natural tip of the molars. The 30° – 45° tip-back (gable bend off center bend, “V” pointing occlusally) in front of the molar tubes precipitates: a small intrusion and labial moment (proclination, flaring) on the incisors.  Large extrusion and distal moment (tipping) on the molars, this renders the dental arch longer, therefore, there should be left 3 – 4 mm arch wire distally to the molar tubes, followed by annealing and bend-back (cinch).
