Surgical approach six months after the conservative treatment. A site-specific full-thickness flap was raised and all inflammatory soft-tissues were thoroughly removed using sharp curettes and degranulation burrs (A). The exposed implant surfaces were cleaned with titanium brushes (B) and then polished (C). Subsequently, blue®m gel was topically applied for 5 mins to hydrate the bone and release oxygen and lactoferrin in the area, in an attempt to decontaminate the implant surfaces and the surrounding tissues, and to enhance the healing (D). After removing the gel and rinsing with sterile saline, guided bone regeneration was performed using a synthetic bone substitute (E) and the flap was repositioned and sutured using 5–0 PTFE sutures (F). Blue®m gel was applied immediately post-operatively and provided to the patient to use twice a day during the healing period (G).
