Abstract: Collagen is the most abundant protein in mammals. Biomembrane made of collagen as the main material has good physicochemical properties and biological activities, which is widely used in bone tissue engineering and other medical fields. In terms of guided bone regeneration (GBR), the collagen membrane has a broad scope in its clinical application as a barrier membrane, but still has disadvantages such as uncontrolled degradation, low mechanical strength, etc. In order to improve these shortcomings, the continuous development of new collagen membranes through cross-linking, mineralization, and surface modification has become the future development trend in this field. In this paper, the application and modification of collagen membrane in GBR was reviewed to provide novel insights into the research and development of new membranes.

Key words: Guided bone regeneration, Collagen membrane, Cross-link, Composites
