Surgitime PTFE is a nonabsorbable membrane composed of Polytetrafluoroethylene, withthickness of 0.10 or 0.25mm. Surgitime PTFE is 100% biocompatible, syntheticand not of animal origin. It is indicated for in orthopedic, neural, maxillofacial procedures and other medical or dental surgery procedures.
The polytetrafluoroethylene (PTFE) membranes or mechanical barriers for RTG (Guided Tissue Regeneration) has the aim of preventing the migration of epithelial and connective tissue cells, which would cause the inhibition of bone growth, promoting suitable space for the formation of a natural fibrin framework, the bone tissue precursor.
The membrane avoids the tissue competition between the connective tissue and the bone, and has the purpose of isolating the bone grafts promoting tissue regeneration. Surgitime PTFE has selective permeability through its porosity, which enables the nutrition of the fibrin framework and simultaneously preventing the passage of bacteria.
