"After the crown is made, you know there's two ways of planning the crown, attaching it to the implant, abutment or post. One is they screw it down or the other way is to cement it on. The recommended way is to cement it on so once the crown is cemented over the post, it stays nice and strong. We don't want the crown to be one piece with the implant and the post. And the main thing is if the bite is not correct, and you're hitting it very hard, a lot of times because of that if it's glued on or cemented on, the crown will pop off. But if it's screwed in, it can't come off, so that pressure continues and some patients will get used to it. And if they do what happens is over time, it will damage the support of the implant. And the bone will disengage and then you're going to have the whole thing in your hand. And this is something that's been proven over and over again. So now with all the crowns that we do recommend it's cemented down instead of screwed in. Once it's cemented down, then you recheck the occlusion, the bite. Make sure it's in the passive bite, and then once we're able to get a passive bite, then it should be very safe and very simple. For single crown that fits well, the cementing itself is within minutes. It's very, very fast. And this type of cement we use is called Improv, it's a glass anomer cement. It has a rubbery base so the excess can peel off very cleanly. We don't have to go in there and scrape it off. So it maintains the high shine of the surface."
