OBJECTIVES The objective of this study was to prepare a novel asymmetric chitosan guided bone regeneration (GBR) membrane, which is composed of a dense layer isolating the bone defect from the invasion of surrounding connective fibrous tissue and a loose layer which can improve cell adhesion and stabilize blood clots, thus guided bone regeneration. METHODS The chitosan membrane was fabricated through liquid nitrogen quencher combined with lyophilization and cross-linked by sodium… CONTINUE READING
