| Abstract: | PurposeTo study the results of an easy orthodontic extraction method for impacted lower third molar removal which had roots compressing to the inferior alveolar nerve (IAN).Patients and methodsForty patients were divided into two groups according to their desire. Orthodontic traction group (n = 20) had brackets or mini bone screws on the antagonist maxillary molars as anchorage for orthodontic traction from 3 to 10 weeks until the roots’ tip was away from the IAN, the tooth was then removed. Traditional extraction group (n = 20) had the tooth removed immediately by the same surgeon. Post-operative results were compared between the two groups.ResultsAll 20 patients in the orthodontic extraction group had their lower impacted third molar removed easily without lower lip numbness after surgery, while 5 patients in the traditional extraction group had transient IAN injury and went away 1 week later. There were no anchorage teeth and adjacent mandibular second molar loose or displacement.ConclusionApplication of orthodontic brackets or mini bone screws on the antagonist maxillary molars is an easy way for orthodontic extraction of impacted lower third molar with roots’ tip compressed to the IAN. It is an effective way to avoid IAN injury during tooth extraction. |
