Acellular Collagen Matrix As a Tool to Obtain Wound Closure Following a Guided Bone Regeneration Procedure

Wound closure is obtained by use of acellular matrix material placed over the exposed barrier membrane. The procedure itself is not part of the research study, nor is the decision to use this procedure, but it is the condition of interest to the research.

Wound from the graft is surgically closed, with no use of the acellular matrix. The procedure itself is not part of the research study, nor is the decision to use this procedure, but it is the condition of interest to the research.
