2018 Annual Session Conference

Influence of the Curve of Spee on Physiologic Anchorage Control

May 8, 2018 8:50am ‐ May 8, 2018 9:35am


Description

Although leveling the curve of Spee is one of the goals in straight-wire technique, natural dentition is not straight. The increasing backward tipping of more posterior molars in the upper arch and the forward tipping of more posterior molars in the lower arch compose the posterior curve of occlusion. Different malocclusions show different curve of Spee and therefore different inclination of posterior occlusal plane. This lecture will discuss what will these features affect our treatment mechanics.

Learning Objectives:

  • Recognize the mechanism of Physiologic Anchorage Loss.
  • Realize the influence of leveling the curve of Spee on anchorage control.
  • Recognize the significance of keeping posterior curve of Spee on anchorage preservation.
