Abstract

Introduction: We reported a case of odontectomy of a Class C or grade 4 impacted upper left third molar (M3) that was surgically removed using alternative classification and technique. Case Report: A 20-year-old woman presented with the chief complaint of pain in the upper left posterior jaw. Clinical examination showed a normal appearance without eruption of upper M3. Panoramic radiograph showed impacted 28 and 18 teeth at the apex region of 27 and 17. Odontectomy was performed in 15 minutes under general anesthesia. The incision was extended from the maxillary tuberosity to the mesial cervicobuccal region of teeth #28 and #16 and continued with a curved oblique buccal incision to the mucobuccal fold. The impacted upper M3 was clearly identified by the presence of bulging on the buccal maxillary bone. Finally, odontectomy and wound closure were performed. Conclusion: An impacted upper M3 may be treated easily by understanding the surrounding anatomic structures. Oral surgery experts can also apply suitable surgical techniques to ease the odontectomy.
