AS17B38C - Three Major Applications of Extra-radicular Screws


Apr 24, 2017 10:45am ‐ Apr 24, 2017 11:15am


Description

Extra-radicular screw placement addresses one of the main challenges of inter-radicular screw placement, that is root interference during a large scale of tooth movement. This lecture will provide application examples of extra-radicular screws in treating sagittal and vertical problems as well as impactions.

Learning Objectives:

  • Identify appropriate screw insertion sites according to the corresponding types of malocclusions.
  • Describe the function of a 3-D lever arm in the force system for impaction treatment.
  • Compare the difference between inter-radicular screw placement versus extra-radicular screw placement.
