In rare cases, impacted second molars may create additional problems for orthodontic treatment. Both parents and the orthodontist should be aware of this problem early to prevent further complications. Good teamwork between the orthodontist and oral maxillofacial surgeon is needed in handling these cases, especially if it involves removing the impacted second molar. The right time to treat an impacted second molar is between the age of 11 to 14 years old. An impacted second molar can lead to a lack of arch length in the patient.


The case report described the management of a female patient with a treated left-and-right impacted second molar in the mandible. The chief complaint of the patient was a protrusive mouth and having two impacted second molars, as told by her general dentist.

Case Report:

A 15-years-old female patient with Class I molar relationship, bilateral second molar impaction, and bimaxillary protrusion visited the clinic for orthodontic treatment. Extraction of four first premolar and mandibular second molar was completed. Both mandibular third molars were moved anteriorly to help close the space.


Good cooperation from various disciplines and treatment planning to resolve the case can produce excellent and ideal results.
