title: [Standardized bone model for incorporation of bone, bone ceramics or other materials into the implant bed].
abstract: To investigate the regeneration of human bone in a good and firm layer, a new model is introduced. It has been developed by us because of therapeutical necessity, but then is continued in the course of further investigations independent from further therapeutical procedure. We use the iliac crest as a bony layer for implants that are the object of research. For the therapy in cases of delayed bone healing, pseudarthrosis, bony defect or corrective osteotomy, the cancellous bone is removed. The empty iliac crest is then filled up with material we intend to investigate. On the occasion of further operations that became necessary because of the underlying bone disease, we had an opportunity to obtain sample of bone and material by hole-drilling through the iliac crest. The bony cylinder can be examined by histological technique. We used this procedure on 105 patients up to now. There were no specific complications caused by this technique at the iliac crest. 37 biopsies could be taken and will now be examined. In future it may be possible to incorporate new bone in this layer for a further therapy and to fill up the lost donor sites.
