AS17B44D - Early Treatment for Class II Crowding with Guided Eruption

Apr 24, 2017 3:00pm ‐ Apr 24, 2017 3:15pm


Reducing time in braces and the burden of care for the Class II crowded and/or protrusive patient while controlling mandibular rotation can be achieved with early primary and premolar extraction. Full cusp Class II correction can be obtained with the use of only a maxillary Nance holding arch as the mandibular molars migrate mesially, the mandible rotates counterclockwise, and incisor crowding unravels and facial balance improves.

Learning Objectives:

  • Diagnose during the mixed dentition cases amenable to guided eruption.
  • Reduce the time in braces and amount of tooth movement needed for the Class I or II crowded and/or protrusive case with guided eruption and serial extraction.
  • Obtain full cusp Class II correction.
