Collagen Bone Block


LegoGraft™, a form of block and ring composed of the porcine-derived bone mineral matrix from cancellous bone and atelocollagen from porcine tendon, is a material used to fill, augment, and/or reconstruct periodontal, oral, and maxillofacial defects.

The bone mineral matrix is similar to the physical and chemical aspects of the mineralized matrix of human bone. Hydrated collagen components have a viscosity that facilitates for the blending of a bone mineral matrix.


With this characterization, it can be trimmed and/or molded to the various shapes of defects and can be attached to the bone defect site.

As time passes, LegoGraft™ is partially transformed by the osteoclast and osteoblast.

Easily Moldable

Made of 90% of THE Graft™ granules and 10% collagen, LegoGraft™ is easier to mold than THE Graft™ granules alone.

Therefore, LegoGraft™ has better handling property compared to that of THE Graft™, making it possible to adapt grafting materials to various shapes of the defect site with more ease.

Optimal Osteoconductivity
Osseous Tissue

While retaining better handling properties, LegoGraft™ is able to form sufficient osseous tissue for implant placement.

And maintain natural volume and great adhesion property which leads to minimum chair time.

Predictable clinical results

With great hydrophilicity, LegoGraft™ stabilizes the clot and aids in revascularization of the graft­ing material in the defect area to increase cell migration efficiency to the mineral substrate.

As a result, fast bone formation can be expected, as well as a predictable clinical result.
