Aim:
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.
Conclusion:
The approach used in the present case is simple and efficient for both traction and retention of a maxillary molar.
