It was determined that the electrical conductivity of titanium implants was the key factor responsible for the biocorrosion process. The interruption of the biocorrosion current resulted in a 4-5 fold reduction of corrosion. We propose a new design of dental implant that combines titanium in zero oxidation state for osseointegration and strength, interlaid with a nonconductive ceramic.

Dr. Lal was working on a ceramic coating before joining ZBH in 2018. Maybe he is in Swindon? In addition to reducing the EM amplification effect, ceramic coatings also reduce the amount of titanium in the blood by reducing corrosion. But again the coating needs to be the right ceramic thats more biologically compatible. Dr. Lal was working with one such substance when he was involved with Life Long Joints projects.
