Background/Aim: A new manufacturing process has been established for the condensation of collagen derived from porcine pericardium to develop a new dental barrier membrane (CPM) that can provide a long barrier functionality. A native collagen membrane (PM) was used as control. Materials and Methods: Established in vitro procedures using L929 and MC3T3 cells were used for cytocompatibility analyses. For the in vivo study, subcutaneous implantation of both membrane types in 40 BALB/c mice and established histological, immunohistochemical and histomorphometrical methods were conducted. Results: Both the in vitro and in vivo results revealed that the CPM has a biocompatibility profile comparable to that of the control membrane. The new CPM induced a tissue reaction including more M2-macrophages. Conclusion: The CPM is fully biocompatible and seems to support the early healing process. Moreover, the new biomaterial seems to prevent cell ingrowth for a longer period of time, making it ideally suited for GBR procedures.
