The word “bioresorbable” means biodegradable, or “naturally absorbing”. For example, a bioresorbable stent or bioresorbable stitches will eventually be absorbed by the body over time. In implant dentistry, bioresorbable materials are often used in guided bone regeneration, or bone grafts. Various animal studies were done to compare the difference between bioresorbable barrier membranes and nonresorbable membranes over a period of six months. In multiple studies, the nonresorbable membranes were shown to have slightly better outcomes than bioresorbable membranes in regards to the regeneration of bone. However, there are significant benefits to using bioresorbable membranes in clinical practice. The primary benefit is that a second procedure to remove the membrane is not necessary, because the body will have absorbed it on its own. This also helps patients avoid risks associated with a second procedure, including anesthesia risks and gingival recession. Although nonresorbable membranes may generate slightly more bone than bioresorbable membranes, many periodontists and patients choose bioresorbable membranes.
