SURGICAL REMOVAL OF BILATERAL MANDIBULAR EXOSTOSIS FOR PROSTHETIC REHABILITATION: CASE REPORT

Abstract

Mandibular torus is an exostosis that develops along the lingual surface of the mandible. The etiology is due to both environmental and genetic factors, and most cases present with a single increase in volume. The peak prevalence of mandibular torus occurs in early adulthood, and it is easily diagnosed on clinical examination. In most cases, there is no need for treatment, however, in cases of oral rehabilitation, surgical removal may be indicated for better accommodation of the total or partial denture. This study aims to report the surgical treatment of bilateral mandibular torus, as pre-prosthetic preparation. The diagnostic method was performed solely by clinical examination, and the presence of bilateral mandibular torus was confirmed, thus initiating planning for exostosis resection and subsequent oral rehabilitation with removable partial dentures. The patient SSPS, a 37-year-old female, sought the UFPE Dentistry Clinic with speech and swallowing disorders, local discomfort and poor prosthetic adaptation. The surgery was performed on an outpatient basis, under local anesthesia, incision and bilateral envelope-type flap. A groove-shaped osteotomy was performed with a 702 surgical drill, excision of the exostosis and regularization of the ridge with a maxicut drill. Then, interpapillary suture was performed with 4-0 nylon thread. After one week, the patient returned to the clinic without complications, the sutures were removed and she was referred for prosthetic rehabilitation. In this way, the patient was able to be effectively rehabilitated, since before the surgical removal of the torus, there was an impossibility of prosthetic adaptation and consequently a change in her quality of life.
