Abstract

Introduction: Possible sensory changes in patients should be one of the concerns of the dentist during surgical planning, making it of high interest of professional techniques to prevent this complication. The intentional partial odontectomy is an alternative to prevent inferior alveolar nerve injury, when the roots of the third molars are in intimate contact with this structure. The technique should be taken during the preoperative planning and involves the removal of the coronary segment of the element in question, atraumatically. Objective: The aim of this study was to report a case of submucosal third molars submitted to coronectomy, describing step by step surgical technique. Case report: Female patient, 26 years old, came to the Oral Surgery Service of Centro Odontológico de Estudos e Pesquisa (COESP), located in João Pessoa, Paraíba, Brazil, for extraction of the third molars. Therefore, it was requested panoramic radiograph, which were observed radiographic signs suggesting proximity of the roots to the mandibular canal. In order to confirm precisely these relations, it was requested CT, and in sagittal sections it was possible to observe the mandibular canal and its relationship with the roots of the third molars, it was still possible to view the root curvature and intimate contact with the nerve. After diagnosis, surgical treatment was initiated based on the principles of the intentional partial odontectomy. It was done postoperative follow-up of 12 and 24 months. The patient is satisfied and no complaints about the loss of sensation and / or infection. Conclusion: When properly indicated and wisely conducted, the intentional partial odontectomy makes it an excellent treatment option, avoiding accidents and unnecessary risks during dental extractions.
