Uprighting Partially Impacted Permanent Second Molars

Abstract

Impaction of the lower second molar is not a common problem, but it is very challenging for both orthodontist and oral surgeon. Treatment options depend on the degree of tooth inclination, the position of the third molars, and the desired type of movement, which may be surgical and/or orthodontic in nature. A good treatment alternative is surgical uncovering with orthodontically-assisted eruption. A case of successful uprighting using a 0.017 x 0.025-inch titanium molybdenum alloy (TMA) tip-back cantilever is presented. Different aspects of uprighting impacted second molars are discussed in light of the literature. The iatrogenic character of lower second molar impaction is emphasized. © 2006 by The EH Angle Education and Research Foundation, Inc.
