[QUOTE="JohnWilson, post: 258278, member: 213"] The milled bar is a sweet way to solve some of the negatives that FCZ has. 1) The weight is substantially reduced 2) Fitting the zirconia to the cad bases is eliminated TIME saved 3) Full control to block substructure with a liner and a MUCH larger cement area. 4) No single cad base will ever be under tension. Even the best verification can lead to minor inaccuracies especially when using Non eng bases and conical connections. Negatives 1) Needs more room 2) Much more risk to do a repair post cementation 3) COST 4) Risk of not sealing off the prosthetic as tissue/bone models over time. What do you do when the ti to tissue developed a gap. 5) Did I mention SPACE? Its just another tool for us that do a bunch of full arches with advanced materials. I am not sure if Bernard's guy "developed" the idea but non the less he is a good, talented and innovative tech for sure. [/QUOTE]
