Managing the healing complications of e-PTFE/d-PTFE membrane in guided bone regeneration: A case Report and Literatures Review
摘要
Numerous different membranes are now available for horizontally or vertically bone augmentation. An expanded polytetrafluoroethylene (e-PTFE) membrane is the first non-resorbable membrane available for dental use. However, once they become exposed to the oral cavity, there is an increased risk of bacteria penetration. A dense polytetrafluoroethylene (d-PTFE) membrane has recently been explicitly designed for use in bone augmentation procedures that seem to assure a fair bone regeneration process even when the membrane is exposed to the oral cavity. Nevertheless, the guided bone regeneration (GBR) failure rate due to membrane exposure can be as high as 31%, which is a high value of complication rate. This review article aims to describe the different classifications of healing complications of using e-PTFE or d-PTFE membranes in GBR. In addition, the management and prevention of these complications, such as membrane exposures or infections, are emphasized in this article.
