A GBR Experience Journey with d-PTFE Membranes

In the eighties and nineties various regenerative materials have been introduced in the fields of periodontics and Implant dentistry. Many of these materials make use of the principle of guided tissue regeneration (GTR), which also includes guided bone regeneration (GBR). The then used non-resorbable e-PTFE membranes could lead to good results and has shown its efficacy in several studies. A considerable disadvantage of this type of membrane however, was that in case of an exposure of an e-PTFE membrane infections often arose and so this led to a (partial) failure. As literature has reported exposure rates from 15%-50% for this type of membrane, this can be seen as a major complication. The introduction of a “new” non-resorbable d-PTFE membrane will eliminate this disadvantage as this type of membrane is non permeable to bacteria. So in case of an exposure, and assuming the right measures are taken, sufficient amounts of bone can still be regenerated. In this presentation a GBR experience journey through time will be presented. The focus will be on the usage of non-resorbable d-PTFE membranes and the conditions that have to be met to achieve successful GBR outcomes. Various indications are illustrated with clinical cases. Also techniques to simplify fixation of the membrane will be discussed. Furthermore, preliminary results of an ongoing study in which this fixation technique is studied will be presented.
