The new wave of gum grafts involve using the donated placenta for an anonymous donor.  While the processing is highly regulated and tested to be completely safe, it is a new material for dental.  The amnion, as it is called, has been used in medical procedures for over a century.  Since April 2009, this product is now available for gum grafts.  The advantage?   Faster healing, less pain, and a shorter surgical procedure.  Sounds good to me.
