What advantage do resorbable membranes have over nonresorbable membranes in GBR procedures?

The advantage of resorbable membranes over nonresorbable membranes in guided bone regeneration (GBR) procedures primarily lies in their reduced risk of causing infections. Resorbable membranes are designed to break down naturally in the body over time, which minimizes the need for a second surgical procedure to remove them, thereby lowering the potential for complications related to infection. Since these membranes are also made from biocompatible materials, the chance of adverse reactions or chronic inflammation is reduced as well.

In contrast, nonresorbable membranes necessitate a return visit for membrane removal, which can increase the risk of infection and other post-operative complications associated with additional surgical interventions. The thickness of the membranes and the degree of support they provide, while important, are not directly related to the advantage of infection risk management. Thus, the specific benefit of resorbable membranes is linked to their ability to integrate into the healing process with less potential for complications, making them favorable in the context of GBR.
