Peri‐implantitis is an inflammatory disease in the mucosa around an implant that results in bone loss and, if allowed to progress, can result in loss of the implant. This disease has been estimated to have a prevalence varying from 11.3% to 56%. To date, there is little evidence to indicate the most effective method of treatment of peri‐implantitis. This report describes a regenerative treatment for restoration of bone and reduction of probing depth (PD) around a peri‐implantitis‐affected implant. Case Presentation: A 67‐year‐old male patient presented with advanced peri‐implantitis around a mandibular right first molar implant that was placed and restored 3 years before his visit. An examination revealed PD of 7 to 12 mm and bone loss of 7 to 10 mm circumferentially around the implant. Treatment consisted of flap reflection, a six‐step surface decontamination, placement of enamel matrix derivative on the implant surface, and fill of the defect with combined allograft/xenografts mixed with platelet‐derived growth factor. The graft was covered with two absorbable collagen membranes, and the flap was coronally advanced and sutured. A 7‐year follow‐up revealed PD reduction of 4 to 10 mm, bone level gain of 3 to 3.5 mm, and no change in the coronal level of the mucosa (no post‐surgical recession). Conclusion: The technique used in this case report resulted in an outcome that saved the implant, brought the peri‐implant tissues back to health, and reduced PD and increased bone support around the affected implant without soft‐tissue recession.
