The maxgraft® bonebuilder concept delivers an innovative approach in ridge augmentation, providing custom-fit solutions for the individual patient’s bone defect. According to the information of CT/CBCT-scans and by using a sophisticated 3-D planning software customized allogeneic bone transplants are designed and prefabricated, so that harvesting and manual adjustment of autologous bone is no longer necessary. The success of the transplant is based on the excellent biological potential of the allogeneic material, as well as on the close contact between the bone bed and the individually designed transplant.

3D construction

The construction of the maxgraft® bonebuilder by our product specialists is based on a CT/CBCT (DVT) – Scan. Therefore an up-to-date scan should be used to allow a precise planning. Additional information like the situation of the soft tissue, possible risk factors and the planned implant treatment are helpful.

Design quality check

The design of maxgraft® bonebuilder has to be checked very carefully before it is released for production. Only the surgeon himself can assess the patients' soft tissue situation and therefore, the required dimensions of the block. The botiss construction team will adjust the design of the block until it perfectly meets the expectations of the clinician.

Rehydration

maxgraft® bonebuilder do not need to be rehydrated. Exposure to liquids before fixation should be kept to a minimum for ease of handling.

Fixation

maxgraft® blocks are fixed with screws for osteosynthesis, preferably with flat-headed screws to avoid perforation of the surrounding soft tissue.

Combination with cerabone® or maxresorb®

Additional void volume should be filled with particulate grafting material to improve the esthetic outcome and to protect the soft tissue.

Guided Bone Regeneration

maxgraft® bonebuilder should be covered by a resorbable barrier forming collagen membrane for GBR (guided bone regeneration) e.g. Jason® membrane to prevent ingrowth of soft-tissue into the bone graft.

Re-entry

Depending on the defect size, the graft will be stably incorporated within 5-6 months.

As harvesting and manual adjustment of autologous bone is no longer required, donor site morbidity, operation time and costs may be reduced significantly.

botiss virtually designs the patient matched allogeneic bone transplant based on CT/CBCT (DVT) -scans of the bone defect. The design of the bone transplant undergoes a final inspection by the clinical user before the individual order is released for production. The botiss partner, Cells+Tissuebank Austria, receives a *.stl milling file and the patient matched allogeneic bone transplant is produced under cleanroom conditions. The resulting allogeneic bone transplant is ready for insertion into the defect with only minor adjustments.

After placement, the maxgraft® bonebuilder block is fixed with osteosynthesis screws. Residual defect volume may be filled with bone regeneration material (i.e. cerabone®) and the augmentation site is covered with a collagen membrane (i. e. Jason® membrane). The strong capillary action of the three-dimensional, porous trabecular bone enables fast and efficient penetration of fluids, nutrients and blood, and reliable and predictable outcomes.
