maxgraft® bonebuilder
Customized allogenic bone block
maxgraft® bonebuilder is a customized allogenic bone block for two-stage alveolar ridge augmentation. 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. The final product is then milled from processed cancellous bone blocks originating from living human donors (explantation of femoral heads during hip endoprosthesis surgery).
In clinical practice, the application of allogenic blocks has been established as a reliable alternative to autogenous bone blocks for alveolar ridge augmentation to avoid donor site morbidity1,2,3 and limitations in material quantity4.
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.5,6 The individual design provides a precise fit between local bone and the allogenic bone block, enabling rapid revascularization and fast graft incorporation.7
Achieve a safe, reliable and predictable clinical outcome
Due to the stable trabecular structure of the cancellous bone, maxgraft® bonebuilder provides an ideal matrix for predictable revascularization, rapid formation of new bone tissue and bone remodeling.7 Simultaneously the biological regeneration capability of maxgraft® is supported by good flexibility on the basis of natural collagen content, which will facilitate screw fixation.
The processing sequence meets high quality standards with regard to biomechanical properties and safety. maxgraft® is storable at room temperature (5-30°C) for 5 years. However, the block should be used as soon as possible after delivery to provide a precise fit, enabling rapid revascularization and fast graft incorporation.

bonebuilder dummy
An individual 3D-model of the patient’s defect, including the planned maxgraft® bonebuilder block(s) printed in synthetic filament, can be ordered together with the maxgraft® bonebuilder and delivered beforehand. The user-friendly demo material helps to inform the patient and supports preoperative planning.

maxgraft® bonebuilder should be rehydrated briefly before fixation with sterile saline solution (e.g. by creating a vacuum in a disposable syringe -recommended by Dr. Blume). maxgraft® bonebuilder consists of a mineralized collagen matrix with a residual moisture content of <10%, rehydration may be useful especially for blocks of bigger and complex dimensions to enhance the adaptability of the material to the specific defect site.

Additional void volume can be filled with particulate grafting material (e.g. maxgraft® or cerabone®) to improve the aesthetic outcome and to protect the soft tissue.
For guided bone regeneration, the augmented site needs to be covered entirely with a barrier membrane, preventing the ingrowth of soft tissue into the bone block (e.g. Jason® membrane).

- maxgraft® bonebuilder should be covered by a resorbable barrier forming collagen membrane (e.g. Jason® membrane) for GBR
- This prevents resorption and ingrowth of soft tissue into the bone graft
