Dr. Iott seems to be a fan of Cerec (computer milled inlays and onlays.) He gave me several inlays and onlays. They are completed within one visit. But one developed a crack within days. Another one broke within 3 months. When they were being done, I didn't like the shape of the surface. Only when I complained, did he redo the onlay by doing what he called a "correlation" between the onlay and the opposite tooth, using the Cerec computer. He should have done this the first time around. He just didn't care.
Also, he doesn't wear a facemask when working. And he loves to talk over my mouth!
