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