ABSTRACT
A 63-year-old male patient, who had a severely resorbed edentulous maxillary arch and partially edentulous mandibular arch decided on the implant-supported fixed treatment option to replace the edentulous maxillary arch. The fully guided implant placement that utilizes the computer-generated guide is more accurate than traditional surgical guides and free-hand placements. The researchers have correlated possible implant failure risk factors with age, sex, smoking, type of edentulism, bone quality and volume, implant location, angulation, diameter, length, and various systemic factors. This case report demonstrated the failure cause of virtually planned anterior implants in All-on-4 and how to manage it by free-hand surgery without surgical guides.
ABSTRACT
Neural tumors of oral cavity is a very rare condition and it occurs because of putative changes in the Schwann cells which surround the axonal process, perineural cells which surrounds the nerve fascicles within a nerve fiber and fibroblast cells. Intraosseous neurilemmoma or schwannoma is one such lesion presenting as a focally expanding area of radiolucency along the course of the inferior alveolar nerve canal in an otherwise asymptomatic patient. Intraosseous schwannomas are rare, accounts to 1% of benign primary bone tumors. This article presents a case with the radiographic presentation of intraosseous neurilemmoma of inferior alveolar nerve in an asymptomatic male patient; represented by focally expanding radiolucency along the course of nerve. The follow-up was maintained for 8 years and subsequent radiographs depict the benign nature of the lesion. Also, the change in subjective symptoms like development of paraesthesia and mild pain associated with the progress of lesion is documented in this case.
