Endodontic surgery aims to remove periapical pathology and regenerate periapical tissues while restoring mucogingival anatomy. An apicomarginal defect, characterized by the loss of buccal alveolus from the crestal bone to the tooth apex, poses a challenge for regeneration due to faster fibroblastic tissue proliferation than bone cells within the defect. Hence, placing barrier membranes over a biocompatible graft material is a common practice. This study reports two cases of persistent symptomatic apical periodontitis, apicomarginal defects, and large periapical lesions managed with endodontic surgery, sticky bone grafts, and guided tissue regeneration (GTR) barrier placements with a 12-month follow-up. Healing potential was evaluated using cone-beam computed tomography (CBCT). Clinically and radiographically examined at 6- and 12-month post-operative, patients were asymptomatic, and follow-up CBCT showed a marked reduction in bone defect area and significant bone density gain. The results indicate that using sticky bone grafts with GTR barrier membranes provides satisfactory bony healing in apicomarginal defects with periapical lesions post-endodontic surgery.
