Impacted molars occur more often in the mandibular arch than in the maxillary arch, with an overall prevalence of .01-1.8%.(1-4) The most common type of impaction, a mesially inclined molar, is also the most successfully treated.(5) Even a horizontally impacted lower second molar can be uprighted. If a molar is diagnosed in a vertical position, however, its prognosis is more compromised and ankylosis should be suspected.(5,6).
