What is one of the main advantages of resorbable GBR membranes?

One of the main advantages of resorbable GBR (Guided Bone Regeneration) membranes is their biodegradable nature, which significantly reduces the risk of infection. These membranes are designed to gradually break down in the body after serving their purpose in supporting the regeneration of bone and soft tissue. This characteristic means that they do not leave foreign materials embedded within the surgical site, lowering the likelihood of adverse reactions or complications such as infections that can occur with non-resorbable implants. The body's natural healing processes can take over once the membrane has disintegrated, promoting a more seamless recovery.

The other options presented do not accurately reflect the advantages of resorbable GBR membranes. While they do eliminate the need for a second surgical procedure for removal, they do not allow for reuse after sterilization, nor are they inherently more effective in bone density regeneration compared to other methods or materials.
