Custom 3D-Printed Resorbable Bone Grafts for Ridge Augmentation

Sound very interesting. I would like to have information about it. Any clinical trials or RCT's studies. please keep me informed.

Exciting times...Computer simulations are helpful to understand the principles, but what would be really great is if we could see some more real life photo's of the actual graft in a patients' mouths (before, after etc.) Do you have more real life cases using this technique?

Hello Greg, I've seen you wrote "There are no formal clinical trials just 6 years of R and D". Did you put together some stats during this period ?

Great stuff Greg as always a thinker . I have been working on this as well in the UK but have had numerous small issues ..... but happy o see good thought precess

i have done one case on 3d printing bone graft in ridge defect area. waiting for 6months

This is not new. Maxgraft Bonebuilder started this several years ago with human allograft.

Sounds good! I'm working with autologous mesenchymal stem cells from patients gingiva, tooth pulp, periosteum and I'm looking for an ideal scaffold. How can I have more information about yours? Thank you

Great use of technology. However, not new at all... you might want to review some of prior art IP... from 15 or so years ago... send me an email and we can discuss... drganz.com

Another approach might be to print a model of the bone defect so that one may prepare the graft in a sterile environment at the office, and repackage it (of course would want to re-sterilized it if possible). I'm thinking an allograft block such as the "J block" or other. Rather than have to spend time in the mouth shaping it, do it ahead of time and then just place it intrasugically. THREE PROBLEMS: 1) cost of the printed model of the defect (any one have an approximate cost of that?) 2) Can the model be printed and sterilized 3) Graft re-sterilization. Is a there a heat below which an allograft block could be sterilized over a given time and not damage the block structure? I would even be willing to set aside a time, same day, prior to surgery to adapt the block to a sterile model in a sterile environment for later use that day if it can't be re-sterilized. I just hate to shape them intra surgically with the mess and the time back and forth between the mouth and trimming field. Can anyone answer the above questions? Has anyone tried this? Thanks, Geoff

Thanks Dr. Steiner Good concept but from a surgical point we are entering unchartered territories both from sterilisation process and cost involved . Can you please SOE ify what osteiibductive material is used here ? Am I right in thinking it is corticocancellous allograft ? Many thanks

Sorry auto correction Specify what osteoinductive material

Hi GBOS , CaP materials especially BTcP are show to have osteo-inductive potential. There are over 200 published papers in medical research . Now even a number of new papers have been published in the lower impact factor Dental journals . As a manufacturer of synthetic graft materials , what is the issue with printing and cad/cam manufacture is more regulatory and sterilization problems . Regards

Oliver, Thanks so much for the feedback. Could you explain why you stopped the technique a little more. Did you not like using block allograft or another allograft method that you liked better. If you didn't like the allograft block was that because of resorption or exposure or what? How much did the bone model cost from 3dblock? Many thanks, Geoff

I heard that a similar product called Allograft Custom Block (by Straumann) is recently available in the US. Has anyone used this?
