Abstract: Guided bone regeneration (GBR) is an important technique in implant dentistry, in which oral collagen membranes play a key role. According to the production process, oral collagen membranes can be divided into acellular matrix membranes, purified collagen membranes and recombinant collagen membranes. At present, acellular membranes are main ones used clinically. Different types of collagen membranes have similarities and differences in production processes, and different production processes also have different effects on the properties of collagen membranes. This paper reviews the classification, production processes, comparison of different collagen membranes and the improvement of collagen membranes.
