Experimental study of radiation sterilization and degradation of polylactide and copolymer membranes for maxillofacial surgery

PLA copolymers demonstrated controlled degradation rates and sufficient structural stability, making them promising candidates for the development of patient-specific resorbable membranes for GBR. Their predictable resorption profile may eliminate the need for secondary surgery to remove the membrane. The results support the feasibility of using ionizing radiation for sterilization without compromising material properties.
