Should we compress biomaterials or not?
Dr. Giulia Cerino | Switzerland, Verena Vermeulen | Switzerland

Does bone regeneration work better in a defect site loosely filled with a bone substitute material, or is compression of the biomaterial beneficial? Prof. Jung-Chul Park, Korea, is among the first researchers to investigate this question in a clinical study. Here he talks with Niklaus Stiefel from Geistlich’s research department about existing evidence and speculation in the field of compressive forces.
