Thank you for your understanding.

maxgraft® bonebuilder


Based on CT/CBCT scans of the patient, the bone block is virtually designed using the latest 3D CAD/CAM (computer-aided design/computer-aided manufacturing) technology.

maxgraft® bonebuilder offers greater precision and accuracy of fit compared to classical block augmentation. Manual adjustment of the block during the operation is seldom required and maxgraft® bonebuilder may be applied directly onto the defect, reducing surgery time as well as risk of infection.1-5 The individual design provides a precise fit between local bone and the allogenic bone block, enabling rapid revascularization and fast graft incorporation.6-7


maxgraft® bonebuilder is planned in close interaction between clinical users and botiss CAD-designers with multiple feedback loops to ensure an optimal fit. Communication is mainly done via email using the comment section on the specific order web page.

maxgraft® bonebuilder is produced at the Cells+Tissuebank Austria (C+TBA), a non-profit organization aiming to provide allogenic transplants for orthopedic and dental regeneration situated in Krems/Austria.
maxgraft® bonebuilder is made from cancellous human donor bone and originates from femoral heads (taken during hip surgery) of living donors from certified procurement centers in Europe.

The ALLOTEC® Process

Thorough donor anamnesis and serological testing combined with the proprietary Allotec® purification procedure and radiological sterilization offer high safety.
