Fig. 5From: Natural graft tissues and synthetic biomaterials for periodontal and alveolar bone reconstructive applications: a reviewDegradable collagen membranes. a Collagen membranes are best cut into the desired shape utilizing a template before final insertion into oral cavity as their manipulation becomes more difficult after being mixed with blood. b Degradable porcine collagen membrane (Bio-Gide®) used to cover and contain FDBA particles during GBR. c Degradable porcine collagen membrane (Bio-Gide®) is often used to cover and contain FDBA particles used for socket preservation. d Degradable porcine collagen membrane (Bio-Gide®) can be stretched over bone graft and stabilized with fixation tacs. e For GBR, a degradable bovine collagen membrane (Biomend Extend®) could be chosen for its longer resorption time and stiffness f The stiff degradable bovine collagen membrane (Biomend Extend®) could be chosen for its relative rigidity and slow absorption timeBack to article page
