maxgraft® bonering

Simultaneous bone augmentation and implant placement

mThe maxgraft® bonering is a prefabricated cancellous ring from human donor bone. The ring allows immediate implant placement and bone augmentation in one step. Therefore the ring technique requires no second surgical procedure. It shortens treatment time till full restoration about several months and therefore increases patient acceptance.

Fast reconstruction of bone without morbidity through second surgical procedure

Due to a multiple step purification process maxgraft® is safe and preserves the advantages of human bone grafts. The human collagen in the ring is responsible for fast integration, healing and flexibility of the ring. A second surgical site to harvest bone and the associated risk of infection, donor-site morbidity and pain can be avoided. After implantation maxgraft® bonering is continuously remodeled into patients own bone. The ring can be used in almost all indications. botiss offers a surgical kit to provide all necessary instruments to apply maxgraft® bonering.

One step augmentation and implant placement

The immediate implant placement through maxgraft® bonering ensures primary stability of the implant and the ring. The technique reduces treatment time and avoids the reentry to place an implant. This reduces morbidity and increases patient acceptance.


Safe and sterile

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 fungi. The final sterilization by gamma-irradiation guarantees a sterility of the packaging and a 5-year self-life at room temperature.

Mineralized collagen

The purification process maintains the structural features and the interconnected macroporosity of human bone. Furthermore it retains its collagen matrix. maxgraft® is composed of approx. 70 % mineral and approx. 30 % of human collagen. The lyophilisation maintains the natural structure of the tissue and a residual moisture level of 5 %. Therefore maxgraft® bonering doesn’t  need to be rehydrated.

Scaffold for ingrowing cells and vessels

The porous structure of maxgraft® bonering allows optimal graft revascularization and ensures the supply with vital cells. The properties of maxgraft® bonering encourage the migration of cells into the surgical site. Therefore a fast bony integration of maxgraft® bonering and the implant is facilitated.

No rehydration needed

The cancellous bone structure and the porosity of the maxgraft® bonering allows fast absorption of blood and the fast suppy of the surgical site with vital cells. The lyophilisation maintains a residual moisture level of 5%. Therefore a rehydration is not necessary.
