INTRODUCTION. I nsoluble type i collagen fibers constitute 90% of the organic matrix of bone, and their degradation is necessary for bone resorption. 1 During this process, type I collagen is cleaved into several fragments in the extracellular phagolysosomal‐like resorption compartment of the osteoclast. GEM dental membranes provide a portfolio of collagen based resorbable dental membranes that meet the needs of various dental indications. Three key design attributes include: Handling characteristics: Conformability vs. Stiffness; Suture pullout strength; Resorption time
