Ridge Preservation Using d-PTFE Membranes: Reinforced and Non-reinforced

A variety of alveolar ridge preservation techniques have been described in the scientific literature. The non-resorbable e-PTFE membranes which were previously available were not suitable for this purpose. An alternative is the usage of a non-resorbable membrane, e.g., a d-PTFE (Teflon) membrane which in contrast to e-PTFE, remains in function if exposed to the oral cavity as it is non-permeable to bacteria. Although sometimes seen as a relative new technique, it has been already described by Dr Bartee in 2001.

This technique has several advantages like for example, a.) preservation of position of the mucogingival junction, b.) exposure of the d-PTFE membrane doesn’t have a negative impact on regeneration as long as the edges are not openly exposed and c.) after removal of the membrane the upper part of the osteoid matrix will reform into keratinized gingiva over time, with a fine wide zone of keratinized tissue as a final result.

In the webinar the technique will be presented and illustrated with clinical cases. Various studies which have shown its efficacy will be discussed including a pilot case series study showing the potential of this technique in severely resorbed sockets.

Learning objectives:
1. The indications of d-PTFE membranes in ridge preservation & restoration procedures.
2. Conditions which have to be met to achieve favorable results.
