The invention concerns a method of treating surfaces and surface-adjacent layers of dental components in particular. A series of several different plasma treatments produces high adhesion between the plasma-treated surface and a layer of plastic applied thereto. The invention also concerns a method of sealing the surface of work by treating it with plasma and covering it with a layer that contains silicate.
