Clinical neurosensory examination and cone-beam computed tomography (CBCT) confirmed extrusion of sealer material into the inferior alveolar canal. Virtual surgical planning was performed, and a CAD\/CAM patient-specific surgical guide was fabricated. Guided piezoelectric corticotomy was used to access the canal and remove the extruded material. Leukocyte- and platelet-rich fibrin (L-PRF) was applied for nerve coverage, followed by reconstruction with autologous fibrin-stabilized bone graft (sticky bone).<\/jats:p>\n                    <jats:p>Postoperative follow-up demonstrated gradual improvement in neurosensory function. Electric pulp testing (EPT) values of adjacent teeth changed from elevated thresholds (55\u201376) to values within normal limits (12\u201334) over a 3-month period.
