maxgraft® blocks



[su_dropcap style=”grey”]m[/su_dropcap] maxgraft® blocks are allograft bone substitute from human donor bone, processed by the Cells+Tissuebank Austria with a special cleaning process (Allotec® process) and available in cancellous and cortico-cancellous form. Due to its preserved natural bone structure and collagen content, it serves as a scaffold for natural bone regeneration and has the potential of complete remodeling into patients’ own bone.


Real alternative to patient’s own bone


The cancellous structure allows an optimal revascularization and supply of vital cells and therefore enables a rapid regeneration of vital bone tissue. Due to a compact and dense bone part in maxgraft® uni-cortical blocks, a greater volume stability is given. For block augmentation maxgraft® blocks are the only real alternative to harvest patients’ bone. A second surgical site to harvest autologous bone and the associated risk of infection, donor-site morbidity, postoperative pain, and loss of bone stability can be avoided. For experienced oral and maxillofacial surgeons, customized allogenic bone blocks, maxgraft® bonebuilder (, are an additional treatment possibility to avoid time-consuming block shaping.

balance between open space and stability

maxgraft® blocks are available as purely cancellous as well as uni-cortical blocks. Whenever contained defects are supposed to be regenerated, the cancellous structure enables a fast bone formation and substitution by vital bone, whereas the uni-cortical block provides more volume stability for example with augmentations outside of the contour.

scaffold for ingrowing cells and vessels

The porous structure of maxgraft allows optimal graft revascularization and ensures the supply with vital cells. The properties of maxgraft® blocks encourage the migration of cells such as osteoblast and osteocytes into the surgical site. Therefore, a fast bony integration of maxgraft® blocks is facilitated.


maxgraft® blocks can, for example, be rehydrated briefly before fixation by creating a vacuum in a disposable syringe filled with sterile saline solution. If possible, mix the saline solution with the exudate serum obtained from preparing autologous platelet-rich fibrin (PRF) matrices. maxgraft® blocks consist of a mineralized collagen matrix with a residual moisture content of <10%. A rehydration may be useful especially for blocks of bigger and complex dimensions to enhance the adaptability of the material to the specific defect site.

Guided Bone Regeneration
  • maxgraft® blocks should be covered by a resorbable barrier forming collagen membrane (e.g., Jason® membrane) for GBR
  • This prevents resorption and ingrowth of soft tissue into the bone graft
  • Depending on the defect size, the graft will be stably incorporated within 5-6 months
  • Product will be degraded when not loaded after healing period
