CLINICAL CASE

Management of Periimplantitis and Implant Replacement with Guided Bone Regeneration with NOVAMag® membrane and mucoderm®

Dr. Marko Blaskovic

A patient presented with periimplantitis affecting an implant placed four years ago. The CBCT scan confirmed the presence of periimplant bone loss around the implant. The initial treatment plan involved the removal of the crown, followed by disinfecting the implant surface while simultaneously regenerating the periimplant bone. However, due to an unexpected implant fracture, the surgical plan had to be altered, necessitating the extraction of the affected implant. The site was thoroughly cleaned after implant removal, and the wound was closed to promote healing. Subsequently, a new implant was placed in the same area. A double layer of NOVAMag® membrane was positioned at the buccal site and fixated with NOVAMag® fixation screws. Bone augmentation was carried out using cerabone® mixed with autologous bone to ensure proper regeneration. To support soft tissue healing, mucoderm® was placed over the augmented site, followed by primary wound closure. After 6 months, implant uncovering took place.
