- Abstract
The treatment of periimplantitis always has two objectives: sufficient decontamination of the exposed implant surface and the surgical manipulation of the soft-tissue flap to modify defect morphology. Various methods and products are available for surface decontamination, from lasers to swabs with antiseptics. A literature search on "regenerative healing" yields a long list of biomaterials and numerous combinations of the same. The "Witten" approach is based on the use of a hypochlorite gel on the implant surface adjunctive to mechanical decontamination by a glycine powder/water jet. The regenerative part of the treatment involves the application of cross-linked hyaluronic acid onto the defect and onto the pre-treated implant surface to hydrate the cross-linked collagen matrix, which then serves as a graft replacing the traditional bone substitute. This approach intentionally omits disconnection of the framework and rejects implantsurface grinding, the "implantoplasty". For two cases, we report the documented changes in clinical parameters after 6 to 12 months and radiographs obtained 12 months after treatment.
