In all the following cases, the d-PTFE membrane was covered with a native collagen membrane. This collagen membrane helps to seal the edges of the membrane, where needed, and potentially aids soft tissue healing (Figs 2-5 to 2-66).

The clinical experience is that the bone quality was better than that at the non-perforated sites. Also, it appears that bone formation is faster than before. It is difficult to say how much faster, but the improved quality means that the bone formation was more rapid. A brave estimation is that an average vertical defect may mature faster by a rate of about 2 months. However, this should be carefully investigated in well-designed randomized clinical trials.

In addition to the preclinical studies, the clinical examples shown in Figures 2-5 to 2-66 are encouraging in their demonstration of predictability and stable crestal bone after regeneration in different clinical scenarios.
