Uprighting mesially impacted mandibular permanent second molars.

Impaction of permanent teeth is a relatively common occurrence and can involve any tooth in the dental arch. Impacted mandibular second molars are relatively rare, but when they occur they may present a clinical problem for the orthodontist and oral surgeon. A typical case of bilaterally impacted mandibular second molars is illustrated, with orthodontic and surgical treatment options presented. Emphasis is placed on early diagnosis and initiation of corrective orthodontic therapy.
