摘　　要：BACKGROUND Intrabony defects beneath non-keratinized mucosa are frequently observed at the distal site of terminal molars.Consequently,the application of regenerative treatment using the modified wedge-flap technique is considered impractical for these specific dental conditions.CASE SUMMARY This article proposes a modified surgical procedure aimed at exposing the distal intrabony defect by making a vertical incision in the keratinized buccal gingiva.The primary objective is to maintain gingival flap stability,thereby facilitating periodontal regeneration.The described technique was successfully employed in a case involving the left mandibular second molar,which presented with an intrabony defect without keratinized gingiva at the distal site.In this case,an incision was made on the disto-buccal gingival tissue,creating a tunnel-like separation of the distal non-keratinized soft tissue to expose the intrabony defect.Subsequently,bone grafting and guided tissue regeneration surgeries were performed,resulting in satisfactory bone fill at 9 mo postoperatively.CONCLUSION This technique offers a regenerative opportunity for the intrabony defects beneath non-keratinized mucosa and is recommended for further research.
