After insertion of a triple BOI implant, large portions of the crestal disks remain outside the bone

The defect can be closed with a mixture of a fibrin membrane and B-TCP. A paracrestal incision is recommended to ensure that the site is tightly closed

A possible alternative to filling with fibrin membranes is the placement of a rigid HA/polylactide membrane, followed by folding back the mucoperiosteal flap (Video 8). The augmentation procedure may be performed also at any time later, after the implant is integrated. In the case shown here, augmentation is an option
