Clinical evidence and Science

Clinical evidence and Science 23 KEY TAKE OUTS: LOAD BEARING CAPACITY The CAMLOG® Tube-in-Tube® connection demonstrated a very favorable load capacity under static as well as dynamic test simulations. The connection has proven to transfer and distribute more than the average chewing forces and to protect the implant from possible failure. 1. Schwarz F, Hegewald A, Becker J.
