Piezo Surgery Clones

Jeffrey, a dentist, asks:
Do any of you have information about new products (clones) in the piezo surgery field?

I’ve heard that some clinician in Paris has had some good results with his piezo unit. Beautiful nerve repositions and amazingly clean chin and ramus grafts. Do these units perform as well as the original? What other comments can I get about piezo surgery? Where can I get more information? Thanks.
