Modified Surgical Stent for Accurate TAD Placement.

The development of temporary anchorage devices (TADs) has allowed for the creation of anchorage in situations where there once was none. Many studies have suggested that the most significant cause of miniscrew failure is insufficient distance between the surface of a root and the miniscrew. In order to reduce the miniscrew failure rate, a modified surgical stent has been shown to not only increase TAD insertion accuracy but also to increase TAD success rates.
