Use of bioresorbable and biodegradable materials for guided tissue and guided bone regeneration is under intense investigation and is being tested in clinical trials. This study presents a basic overview of material properties of bioresorbable and biodegradable polymers and devices for guided tissue and guided bone regeneration treatment. Collagens and aliphatic polyesters, such as poly(glycolic acid), poly(glactic acid), and polycaprolactone, are discussed, as well as biocompatibility, mechanical properties, and sterilization. Keywords: biocompatibility, bioresorbable device, bioresorbable polymer, guided bone regeneration
