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.
