So what you are saying is that the Legacy System, developed by Niznick in 2007, with surgical and prosthetic compatibility to Zimmer's Tapered Screw-Vent that he developed in 1999 and sold to Zimmer in 2001, (was an improvement on his 1986 straight Screw-Vent) "is a Copy of that implant." He sure didn't copy it very closely since the Legacy does not have a vent, has micro-threads and a longer cutting groove. ITS CALLED EVOLUTION! If it were a copy, he should have called it "Screw-No-Vent". Regardless, Implant Direct sure ate Zimmer's lunch with that implant....and his RePlant did the same to Nobel Biocare which had 5 straight years of lost sales after Implant Direct launched that product. Both of those companies were bought or merged with other companies in no small part due to Niznick's ability to read the market and realized that dentists wanted value as well as quality and innovation. Yes Niznick is gone from the management of Implant Direct BUT he still owns 25%. His name is used through Implant Direct's website so Danaher must believe Implant Direct benefits from his imprimatur.
