The shell technique creates space between local bone and the cortical plate. This space can be filled with a variety of different particulated bone grafting materials. E.g. maxgraft® granules with its human collagen that provide excellent osteoconductivity properties and enable complete remodeling. The additional use of autologous chips and/or particulated PRF matrizes can support the ossification. This container facilitates revascularization and migration of bone-forming cells into the defect and fast bone regeneration.

maxgraft® cortico should be covered by a resorbable barrier forming collagen membrane (e.g. Jason® membrane) for GBR. This prevents the ingrowth of soft tissue into the bone graft. Furthermore tension free and saliva proof sutures are crucial for the success of the augmentation.

maxgraft® cortico is a rigid and stable strut for the shell technique. It should be fixed onto residual bone with osteosynthesis screws that have a flat screw head. Ideally 2 screws should be applied to prevent rotation.

The certified production process at the Cells⁺ Tissuebank Austria (C⁺TBA) ensures highest safety standards. The process involves donor selection, serological testing and a wetchemical purification process to eliminate bacteria, virus, proteins and fungus. The final sterilization by gamma-irradiation guarantees a sterility of the packaging and a 5-year self-life at room temperature

Rehydration of maxgraft® cortico is recommended. It has been shown that rehydration of maxgraft® cortico (10 minutes in saline solution) results in more flexibility and improves the breaking strength of the strut (Pabst et al., 2020).
