This is how GTR works: the GTR membrane serves as a barrier that separates fast-growing gum tissue from the newly cleaned surface of the tooth root. This enables slower-growing fibers and bone cells to migrate into the protected area. 

Because you and your doctor have chosen to use an absorbable Type I collagen membrane from Zimmer Dental, a second removal surgery is unnecessary. BioMend® membrane will absorb within 8 weeks and BioMend Extend will completely absorb within 18 weeks following surgery. 

Collagen is a natural material that has been used for many years in medical products. Collagen is the most abundant protein in the animal kingdom. BioMend membrane is made of bovine Achilles tendon, one of the purest sources of Type I collagen available.
