The InnoGenic Wifi-Mesh, PTFE-Plast and Ti-Mesh are non-resorbable barrier membrane to be applied over intraoral defects, especially tooth extraction and bone augmentation sites. The InnoGenic Wifi-Mesh and PTFE-Plast are made of proprietary 100% PTFE, the polytetrafluoroethylene (teflon) sheet which is a biologically inactive and tissue compatible material and the InnoGenic Wifi-Mesh is reinforced with titanium frames (Titanium Gr II, ASTM F 67) embedded between two layers of PTFE sheets.
