Characteristics: Dual-Block is a cortico-cancellous block of xenogenic bone with osteoconductive characteristics. It can be used when the regeneration of big volumes is needed: thanks to the collagen content that promotes blood clotting and migration of regenerative and repairing cells⁽¹⁾, the graft offers an adequate support for tissue reconstruction and is gradually resorbed, while new bone is produced by osteoblasts.
Handling: Dual-Block must be hydrated before use with sterile lukewarm physiological solution or with antibiotics (5/10 minutes for Soft version; up to 40 minutes for Norm version). Afterwards, the block can be adapted to the receiving site which must be accurately decorticated in order to guarantee maximum contact; the block should always be fixed with osteosynthesis microscrews and protected with Evolution membrane.
Clinical information: Dual-Block can be grafted with the onlay technique only to augment horizontally heavily resorbed maxilla. The gaps around the block can be filled with a biomaterial in granules to achieve the desired volume and contour of the augmented recipient site.

The above clinical information is based on the experience of expert surgeons
