In vivo evaluation of the biocompatibility and biodegradation of a new denatured plasma membrane combined with liquid PRF (Alb-PRF).

Guided bone regeneration (GBR) is a process that involves the regeneration of bone defects through the application of occlusive membranes that mechanically exclude the population of non-osteogenic cells from the surrounding soft tissue. Interestingly, platelet-rich fibrin (PRF) has previously been proposed as an autologous GBR membrane despite its short-term resorption period of 2-3 weeks. Recent clinical observations have demonstrated that, by heating a liquid platelet-poor plasma (PPP) layer and mixing the cell-rich buffy coat zone, the resorption properties of heated albumin gel with liquid-PRF (Alb-PRF) can be significantly improved.
