Mulligan Mechanics Part IV Mulligan Intrusion Arch
By Dr. Adrian J. Palencar, MUDr, MAGD, IBO, FADI, FPFA, FICD
December 2024

Do not memorize, understand – Dr. T. Mulligan

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-forward (gable bend off center bend, “V” pointing gingivally) in front of the molar tubes precipitates: a small extrusion and lingual moment (de-torquing, up-righting) of the incisors. Large intrusion and mesial moment (tipping) on the molars, this renders the dental arch shorter, therefore, place a bend-back (cinch) distally to the molar tubes.

The amount of the applied force should be measured with the Gram gage (do not exceed 70 grams).

The Mulligan Retrusion Arch is indicated for retracting flared incisors and is very easy to fabricate. Place 4.0 – 5.0 mm 90° step up bend, just 2.0 mm distally to the lateral incisors. The bend of the horizontal arm should be more acute. The Mulligan Retrusion Arch may be passive, intrusive, or extrusive, depends on if you activate it with a tip-back or tip forward.

The retrusion is done by pulling the arch wire back 1.0 mm and a bend-back (cinch) every month, until the desired result is achieved.

Dr. Adrian Palencar generously continues his popular series of Monthly Tips for the Iao Headquarters . The November tip is titled 'Mulligan Mechanics Part V:
Mulligan Extrusion Arch'. This tip and all past archives can be accessed on the Members Only section of our website at any time. Visit iaortho.org to learn more.

Mulligan Mechanics Part V: Mulligan Extrusion Arch
By Dr. Adrian J. Palencar, MUDr, MAGD, IBO, FADI, FPFA, FICD

Do not memorize, understand – Dr. T. Mulligan

The Mulligan Extrusion arch is a two-couple extrusion arch wire used for control of anterior open bite It is commonly made with round wire (a .020 or a .018 SS), attached to the teeth only at the molars and the incisors and is activated for incisor extrusion by a molar tip-forward (off-center, gable) bend. Dr. Mulligan used a .020 ss arch wire, however, the author prefers a .018 SS arch wire – as there is less friction and biding.

The Extrusion arch is activated by one squeeze of the Tweed loop forming pliers – “V” pointing gingivally, just in front of the molar tubes. This one squeeze creates approximately 45° tip back (off-center bend), if less is desired, squeeze less. In author’s opinion, it is paramount to apply these bends extra-orally.

Analyzing the result of the tip-back; there is a long arm mesially – pointing in the direction of the force (extrusion of incisors) and creating lingual moment (de-torquing – up righting incisors). Distally of the tip-back; there is a short arm pointing opposite of the direction of the force (intrusion of the molars) and creating mesial moment (mesially tipping the molars).

Remember, the long arm points in the direction of the force. The short arm points opposite to the direction of the force.

Is not there an analogy between the teeter-totter and the Extrusion arch?

The Mulligan intrusion arch renders the dental arch shorter; the only obvious application may be a dental anterior open bite with a spaced dentition and flared maxillary incisors.
