The cortical membrane
is a thin layer of cortical bone made flexible thanks to a proprietary demineralisation process.
The advantage of this membrane is the long protection time
histologics show it is still occlusive after 6 months from being grafted. Nonetheless it is totally remodelable, so there is no need for second surgery to remove it.
It is indicated to protect all those graft when regeneration is believed to occur slowly
(lacking of bone walls, great volume to be regenerated).
Proper fixation is mandatory
