maxgraft® cortico spares the patient the possible source of complications of autologous bone harvesting, the donor site morbidity, as well as the associated pain, which is often greater than with the augmentation itself. The practitioner is also spared the need to divide the bone block and the time-consuming thinning of the bone platelets.

The shell technique creates a biological container between the local bone and the cortical plate. This free space can be filled with the surgeon’s preferred particulate bone substitute material, such as maxgraft® granules or autologous bone chips. The osteoconductive characteristics of maxgraft® allows natural remodeling.

Postoperatively, maxgraft® cortico is primarily integrated. Since the bone plate consists of cortical bone, it is not rapidly resorbed by the body but gradually remodeled. New vital bone forms directly on the side of the allogenic plate facing the local bone. Compared to autologous bone plates, maxgraft® cortico shows comparable, sustained stability.

Rehydration of maxgraft® cortico is recommended. Rehydration of maxgraft® cortico (10 minutes in saline solution) has been shown to increase flexibility and improve the fracture strength of the plate.

maxgraft® is processed bone graft substitute material from human donors. maxgraft® cortico is completely mineralized cortical bone and originates from the femoral diaphysis of post mortem donors. Procurement is standardized according to a predefined procurement protocol and is performed by certified procurement centers. All tissue donations are made 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 rigorous serological tests in combination with the Allotec® purification process of the C+TBA 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.
