Cyanoacrylate Tissue Adhesives in Peri-Implant Surgery: A Case Report and Surgical Technique

Cyanoacrylate tissue adhesives have been proposed as an adjunct or alternative to sutures in periodontal and peri-implant surgery, offering hemostasis, bacterial sealing, and improved wound healing. However, their clinical application remains scarcely documented. This case describes the adjunctive use of n-butyl-2-cyanoacrylate in combination with sutures for donor site stabilization during peri-implant soft tissue grafting in a 67-year-old female patient rehabilitated with implants in the maxillary right quadrant. A free gingival graft was harvested from the palatal premolar region and secured with sutures and cyanoacrylate adhesive, while the recipient site received a split-thickness flap under local anesthesia. Healing was uneventful, with complete graft integration and stable keratinized mucosa formation in the donor site after 30 days. No inflammation, infection, or necrosis was observed, and postoperative discomfort was minimal. The adjunctive use of cyanoacrylate provided rapid hemostasis, effective wound protection, and enhanced patient comfort, suggesting a simple and clinically feasible approach to soft tissue management around implants. However, these findings are based on a single case and should be interpreted descriptively.
