Goal-oriented positioning of upper second molars using the palatal intrusion technique.
This article describes an orthodontic mechanical variation to reduce prominence of the palatal cusp of the upper second molar and to correct buccal crossbites in the molar area. By using a modified transpalatal arch with a soldered spur, a button bonded to the palatal surface of the second molar, and an elastic chain intrusion of the palatal cusp with control of buccal root torque is accomplished. The palatal intrusion technique provides a simple and very efficient approach to correct upper second molar position.
