Introduction: The teeth spontaneously erupted into excellent positions without surgical procedures. A permanent teeth fails to erupt and is often displaced into ectopic positions in the upper and lower jaw in the maxillofacial region. We report a rare case of an impacted right secnd and third molar of mandibular. The buried teeth were embedded in the mandibular molar area. This raises important questions concerning the possible treatment options for such teeth as well as the timing of any interceptive treatment.
Tooth extraction is a very common procedure in oral surgery. There are many complications in tooth extraction, especially Inferior Alveolar Nerve (IAN) injury and Iatrogenic Fracture of Mandible (IFM). This case report describesthe third molar close to the IAN and the crown under the first molar, showing that it is important to protect the INA and molar.
Case presentation: A 22-year-old man was referred to the Department of Implantology, Stomatology Center, Central South University Xiangya School of Medicine Affiliated Haikou Hospital with a chief complaint of the molar miss in the right side.He had no significant past medical history, social, environmental, family and employment history. He does not smoke, and/or consume alcohol.The temperature, pulse, blood pressure and temperature are normal on admission. A dental check revealed absence of right mandibular third molar, Mesial impaction of right mandibular second molar with mesial caries. CBCT revealed that the tooth was found in the apex of first molar and near the inferior alveolar nerve canal. Diagnoses were #47 #48 impacted wisdom teeth. The Wisdom teeth were removed by precise surgery. The wound healed well without infection or nerve damage. There was no complaint.
Conclusion: The impacted wisdom tooth described in this case report was close to the IAN. We evaluated the relationship between tooth and IAN with CBCT. Then impacted teeth were safe to be removed by precise surgical procedure under CBCT guidance.
