Synthetic bone grafts in peri-implant bone dehiscences: histological results in humans

This study describes the histological results found in three patients treated with osseointegrated implants and Bioplant HTR (Hard Tissue Replacement) synthetic bone graft in peri-implant dehiscences adjacent to implants. This therapy was carried out without the use of barrier membranes. Bioplant HTR is reported to act as its own barrier and prevent gingival soft tissue migration ingrowth. The histologic picture demonstrated that Bioplant HTR is osteoconductive and biocompatible, and can be used both as bone substitute and as a barrier for guided bone regeneration in implant therapy.
