38 I I industry report _ bonebuilder technology It is a technique-sensitive and time-consuming process. More- over, the prolonged exposure of the surgical site to saliva and air increases the risk of infection and delayed wound healing. _Customised allogenic bone transplants for onlay block grafting botiss offers a new technology thatprovidestheclinicaluserwitha pre-fabricated,customisedallogenicboneblock,which isindividuallydesignedtomatchthepatient’sdefect. The individual maxgraft bonebuilder block (Figs.1&2)isdesignedusing3-Ddigitalradiographs (CBCT) of the defect and CAD/CAM technology. The radiological data is transferred into CAD/CAM planning software that builds a 3-D digital model of the scans (Figs. 3–6, patient data provided by Dr Markus Schlee, Forchheim, Germany). Based on this virtual model, the botiss specialists design the allograft block directly on the virtual defect with Figs. 13–15_Handling of maxgraft bonebuilder in surgery. Fixation by osteosynthesis screws, filling of residual gaps with bone regeneration material (here: botiss cerabone), covering of the augmentation site with a collagen membrane (here: botiss collprotect membrane), and tension-free wound closure.
