Can PentOS OI™ Flex be used without a membrane?
If primary closure is not possible, the use of a membrane is highly recommended.
Normally, a dental membrane is used to prevent the epithelial cells from growing into the bone graft site, where new bone is forming.
A Neomem® membrane also helps to keep the granules at the graft sight, preventing migration of the granules. A membrane is also used when primary closure is not possible. However, if the periosteum is still intact, it can be used to achieve primary closure.
