When to choose allografts?

Allografts are processed human donor bone and a well-documented choice for bone augmentation. The material has the natural bone structure and the preserved collagen and, over time, remodels into the patient’s own bone.

The advantage is that no bone has to be harvested from the patient – saving operating time, pain and the risk of complications. We supply allografts from two tissue banks: maxgraft® from botiss, processed at C+TBA in Austria, and DIZG in Berlin, with whom we have worked since 2015.

  • Remodels into the patient’s own bone
  • No secondary surgical site
  • Granules, sticky bone, plates and blocks – also patient-specific
  • Two tissue banks: C+TBA (maxgraft®) and DIZG

How maxgraft® is made: the Allotec® process

At the C+TBA tissue bank, the donor bone is processed in six steps that clean the tissue and preserve the natural bone structure.

  1. Shaping

    After mechanical removal of soft tissue, fat and cartilage, the tissue is given its final shape, e.g. block, granules or cylinder.

  2. Ultrasonic bath

    Ultrasonic cleaning removes blood as well as cell and tissue components and loosens fat from the trabecular structure of the bone, so that the reagents in the following steps can penetrate.

  3. Cleaning with volatile reagents

    Repeated rinsing with diethyl ether and ethanol dissolves cellular components and denatures non-collagenous proteins. Any viruses are inactivated and bacteria are destroyed.

  4. Oxidative treatment

    Hydrogen peroxide denatures the remaining soluble proteins and reduces antigenicity to a minimum. The collagen matrix remains intact.

  5. Freeze-drying

    Lyophilisation gently removes the water and preserves the structure of the tissue. Residual moisture of no more than 10 % and double packaging give a shelf life of up to five years at room temperature.

  6. Final sterilisation

    A final, tissue-preserving irradiation at low temperature – together with the preceding cleaning steps – gives a sterility assurance level (SAL) of 10⁻⁶.
