m maxgraft® is a sterile and safe allograft product from human donor bone, processed by the Cells+Tissuebank Austria. Due to a multiple step purification process maxgraft® is safe and preserves the advantages of human bone grafts. The human collagen is responsible for fast integration, healing and flexibility of the graft. The excellent biological regeneration capability of maxgraft® results in a predictable clinical outcome.
maxgraft® is a natural human bone matrix that serves as a scaffold for natural bone regeneration. 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.

maxgraft® is available as purely cancellous as well as cortico-cancellous granules and blocks. Whenever contained defects are supposed to be regenerated, the cancellous structure enables a fast bone formation and substitution by vital bone, whereas cortico-cancellous products provide more volume stability for example with augmentations outside of the contour.
The certified production process at the Cells+ Tissuebank Austria (C+TBA) ensures highest safety standards. The process involves donor selection, serological testing and a wet chemical purification process to eliminate bacteria, viruses, proteins and fungus. The final sterilization by gamma-irradiation guarantees a sterility of the packaging and 5 years shelf-life at room temperature.
The purification process keeps the structural features and the interconnected macroporosity of human bone. Furthermore, it retains its collagen matrix. maxgraft® consists of 70% mineral and 30% organic phase.

The porous structure of maxgraft allows optimal graft revascularization and ensures the supply with vital cells. The properties of maxgraft® encourage the migration of cells such as osteoblast and osteocytes into the surgical site. Therefore, a fast bony integration of maxgraft® is facilitated.
The cancellous bone structure and the porosity of maxgraft® allow fast absorption of blood and a fast supply of the surgical site with vital cells. The lyophilisation maintains a residual moisture level of 5%. Therefore a rehydration is not necessary.
