Mechanical Debridement of a Peri‐Implant Osseous Defect With a Novel Titanium Brush and Reconstruction With Porous Titanium Granules: A Case Report With Reentry Surgery

Introduction: The scientific evidence for one specific treatment strategy for peri-implant osseous defects is scarce. It will be important to develop methods for efficient decontamination of ailing implants and for reconstruction of lost peri-implant osseous attachment. Access for instrumentation of narrow peri-implant defects is difficult, and to the best of our knowledge, this case report describes, for the first time, the use of a novel titanium brush for mechanical debridement of the implant surface and the defect. Histologic evidence that porous titanium granules (PTGs) support reosseointegration has recently been reported.Case Presentation: A healthy female patient had two implants placed for prosthetic rehabilitation of teeth #21 and #23. In conjunction with second-stage surgery, a buccal osseous defect was disclosed at the most anterior implant. The narrow and deep defect was debrided with a novel titanium brush, chemically decontaminated with 3% H2O2, and filled with PTGs. In conjunction with sec...
