Dr. Orcan Yüksel is – together with Bernd Giesenhagen – the inventor of the allogenic Bone Ring Technique. They have developed an augmentation technique which allows bone transplantation and implant placement to be performed on large three-dimensional bone defects in a single surgery. Our colleague Nathalie Martin is talking with him about his long cooperation with botiss, the development of maxgraft® bonering and the technique itself. Orcan and Bernd have placed more than 1000 rings successfully – we are looking forward to Orcan sharing his experiences with us.
