About

The aim of this clinical study was to compare the effects of traditional and orthodontic extraction methods on postoperative nerve damage in impacted third molars associated with the inferior alveolar nerve. The main question it aims to answer is:

-Does the orthodontic extraction method reduce the risk of nerve injury compared to traditional extraction?

Participants will:

• undergo either traditional or orthodontic extraction
• be monitored for postoperative paresthesia.

Researchers will compare traditional and orthodontic extraction methods to see if extraction methods affect postoperative nerve damage.

Full description

The extraction of an impacted mandibular third molar is one of the most frequently performed procedures by oral and maxillofacial surgeons. The close anatomical relationship between the root of an impacted mandibular third molar and the inferior alveolar nerve may result in inferior alveolar nerve damage. The incidence of inferior alveolar nerve injury during the removal of an impacted mandibular third molar ranges from 0.35% to 8.4%. In addition to radiographic analysis, various surgical techniques, such as coronectomy, have been proposed to reduce the incidence of inferior alveolar nerve injury.

The orthodontic extraction technique is an orthodontically supported surgical approach that reduces the risk of neurological complications that may occur in inferior alveolar nerve and facilitates the surgical removal of impacted mandibular third molars close to the mandibular canal, even if they are associated with cystic lesions.

The purpose of this study is to examine the effect of orthodontic extraction applied to minimize inferior alveolar nerve damage during the extraction of deeply impacted mandibular third molar teeth on postoperative nerve injury. For this purpose, the postoperative paresthesia findings of patients who underwent orthodontic extraction will be compared with those of those who underwent traditional extraction.
