title: Impacted mandibular second molar with extruded maxillary second molar: a case report.
abstract: OBJECTIVE
  To present a method for correction of an extruded maxillary second molar.
  
  
  METHODS
  A female patient, 16 years of age, presented with an impacted mandibular second molar and an extruded opposing maxillary second molar. After placement of appliances in the maxilla, an elastic was hooked between the distal end of the extended lingual arch and the lingual button of the maxillary second molar.
  
  
  RESULTS
  After sufficient intrusion of the maxillary second molar was achieved, the conventional method for traction of an impacted mandibular second molar was used. Neither root resorption nor undesirable periodontal problems were observed.
  
  
  CONCLUSIONS
  The approach used in the present case is simple and efficient for both traction and retention of a maxillary molar.
