Simultaneous approach: Repair of a dehiscence defect during implant placement by Dr. Claude Andreoni and Dr. Thomas Meier Fig. 1 Status after insertion of the implant (SPI ® , Thommen Medical AG). A Fig. 2 After covering the exposed implant sur- face with bone chips from the surrounding area, the Geistlich Bio-Oss ® granules are applied using the Geistlich Bio-Oss Pen ® . 4-ye Follo ar w-up Fig. 3 Covering of the graft with two layers of Geistlich Bio-Gide ® . Here the collagen mem- brane is applied using the “double layer” tech- nique to stabilize the graft and protect it from the ingrowth of soft tissue.

Sequential approach: Reconstruction of the alveolar ridge in a fenestration defect immediately after tooth extraction with implant placement at 7 months by Dr. Claude Andreoni and Dr. Thomas Meier Fig. 1 Flap formation showing the extraction socket. The large labial fenestration defect is clearly visible. A 16 months after grafting Fig. 2 The fenestration is too large for sing- le-stage implantation with bone grafting. The- refore, a two-stage approach is opted for. First, the infected tissue is completely removed, be- fore the extraction socket is filled with Geistlich Bio-Oss ® Collagen. 5.5-y Follo ear w-up Fig. 3 For stabilization of the graft and protec- tion from ingrowing soft tissue, using the “dou- ble-layer” technique, the socket is covered with two layers of Geistlich Bio-Gide ® .
