Re: Heat generation and drill wear during dental implant site preparation

We studied with interest the paper "Heat generation and drill wear during dental implant site preparation: systematic review" by Möhlhenrich et al, which provides valuable data about drilling bone. They describe "drill material" as "zirconium coated with steel", whereas because of the mechanical and thermal stresses at the interface of the drill and the bone, the material's resistance to wear must be a coating for the drill.1
