Ti-PTFE
Titanium Reinforced Buccal Singles 24mm x 17mmx8mm. 
PTFE ( Polytetrafluoroethylene ) 
Ti-PTFE Regenerative Membranes are temporarily implantable material
Ti-PTFE Regenerative Membranes are  sterile non absorbable membranes made from polytetrafluoroethylene (PTFE) polymer reinforced with a medical grade Titanium embedded between two layers of PTFE. 
PTFE is a biologically inert and tissue compatible material. The Ti-PTFE Regenerative Membranes have been proved to be pyrogen free.
