ABSTRACT:
The present invention is directed to collagen membranes having physical and biological properties which make them extremely suitable and desirable for all types of medical uses, particularly as a periodontal barrier. The membranes are characterized by having a surface roughness morphology similar to leather and are translucent. Moreover, these membranes do not swell appreciably upon being wetted so as to maintain their overall bulk density. Methods for preparing these membranes and applications for their use are also disclosed.
