It is commonly admitted that "rough" surfaces promote osseo-integration of dental implants. Numerous studies emphasize an optimal Ra parameter for this purpose. One very common way to achieve that state is the so-called "grit blasting" process whereby tiny ceramic (alumina) particles are shot on the implant's surface.
Up to here for the basic story.
It has also been noted in other instances that surface blasting may not be entirely beneficial and it should be controlled, in terms of blasting pressure, particle size and shape.
We show in the attached paper how poorly controlled blasting treatments can actually degrade the surface of the implant to the point where cracks are formed. From here, the end of the story is obvious for a mechanician.....
