The perforated membrane shows that the clinician may expect better bone quality and faster bone formation. It also sheds light on how to use growth factors. Autogenous particulated bone has several growth factors such as BMP-2 and transforming growth factor beta 1 (TGF-B1), hence these results can likely be applied to the autograft/xenograft mixture that is used throughout this book. In some cases, the author has used the Lasagna type of graft with excellent results.

It is also clear that the periosteum should not be blocked, and if a collagen membrane is used, it should be a native collagen membrane that resorbs as rapidly as possible. Crosslinked collagen membranes should not be used over perforated PTFE membranes. Also, particulated bone chips may release more BMP-2 than an autogenous cortical block.
