maxgraft® blocks are available in pure cancellous and uni-cortical forms. For the regeneration of bone defects, the cancellous structure of the purely cancellous blocks enables rapid regeneration of vital bone tissue, whereas the uni-cortical blocks offer more volume stability, for example in augmentations outside the ridge contour.

maxgraft® blocks consist of a mineralized collagen matrix with a residual moisture content of <10%. Nevertheless, rehydration is recommended (10 minutes in physiological saline solution). maxgraft® blocks can also be briefly rehydrated in a disposable syringe under vacuum in physiological saline solution (technique according to Dr. Blume). Rehydration can improve the adaptability of the material (especially with large blocks) to the defect.

maxgraft® is processed allograft from human donors. All cancellous blocks originate from femoral heads of living donors donated during hip arthroplasty surgery. Uni-cortical blocks with a cortical component are from post-mortem donors. Procurement is standardized according to a predefined protocol and is performed by certified procurement centers. All tissue donations are performed only after the donor has given written consent. In addition, the health status of each potential donor is assessed in advance as part of a risk analysis and the donor is then selected on the basis of strict exclusion criteria.

After a thorough analysis of the donors’ medical history, the high safety of maxgraft® is ensured by a series of stringent serological tests in combination with C+TBA’s Allotec® purification process and final radiological sterilization.

C+TBA is certified as a tissue procurement facility and tissue bank according to §19 and §22 of the Austrian Tissue Safety Act.
