Guided bone regeneration (GBR) procedure has produced acceptable results while utilizing various barrier membranes. Among the membranes used, expanded PTFE (e-PTFE) was the first material to demonstrate successful outcomes and it became the gold standard for GBR. However, early bacterial infection with membrane exposure affecting bone regeneration was the main drawback of e-PTFE. On the contrary, high density polytetrafluoroethylene (d-PFTE) ensures a good bone regeneration process in spite of membrane exposure in the oral cavity, and it also presents with a lower risk of early infection after surgical procedures. The purpose of this review is to provide an amendment to the existing knowledge about the GBR with special emphasis on the d-PTFE barrier membrane used for GBR. The relevant literature for this review was identified through a PubMed, MEDLINE, Scopus, and the Cochrane Library database search. Eleven articles that evaluated the use of d-PTFE as a barrier membrane for GBR were identified: two experimental studies and nine clinical studies. Considering the potential benefit they offer, d-PTFE is a favorable candidate for GBR. However, a careful surgical approach and thorough knowledge of the materials and management of complications significantly contribute to the success of GBR while utilizing d-PTFE.
