Orthodontic traction in dentigerous cyst treatment: a case report

26729

INTRODUCTION: Impacted third molars increase the risk of cystic follicular tissue changes. The presence of impacted third molars and bone defects caused by cysts increase the risk of mandibular angle fractures during surgical procedures. The aim of this case presentation was to describe an alternative method for the extraction of an impacted third molar where a miniscrew was used for the orthodontic traction of the impacted tooth and, thus, a mandibular angle fracture risk as well as the amount of bone defect was reduced. CASE REPORT: A 68-year-old male patient had been referred to the Department of Oral Surgery, Ege University with pain and swelling complaint at the third molar area. His panoramic radiograph revealed the presence of a dentigerous cyst and a severely impacted third molar at the mandibular angle. Following the intraoral and radiographic evaluation, a miniscrew was inserted into the buccal cortex between the canine and first premolar. An attachment was bonded to the available exposed surface of the impacted molar and light, continuous extrusive force was applied with a coilspring. A powerarm was used in order to bypass the soft tissue curvature and to prevent soft tissue impingement. After a traction period of 8 months, the molar was surgically removed. CONCLUSION: Orthodontic extrusion of impacted molars with miniscrews prior to surgical removal may be an alternative treatment option for reducing the risk of mandibular angle fracture in the presence of bone defects.
