In my New York City dental practice it takes a week or two for my dental laboratory to return a completed crown. I allow them this time to allowt them not to be rushed and give them a chance to do their best work. The porcelain for these crowns is 'hand stacked' by a ceramicist and is highly esthetic.
Recently a new technology is becoming more popular involving cad cam technology that allows dentist to fabricate same day crowns. Examples of this are Cerec and E4D cad cam machines and where indicated these machines can impression and mill restorations in a single day. These one day crowns are not optimal for all situations since they can not utilize a bevel preparation and probably the esthetics can be better on more customized traditional 'hand stacked' porcelain crowns.
Several of the dental practices in my building have invested in this technology and they seem happy with it. My good friend and collegue Dr Jay Schuster has recently installed one of these systems in his dental practice in Morristown New Jersey and he has invited me to observe the system in action and I look forward the opportunity to learning more about this process.
Hmn... this is the first time I heard of same-day crowns. I think it's amazing.
ReplyDeleteI got one in Salt Lake City. It was cool watching the small mill machine it in about 25 mins. But I also heard the hand made porcelain ones are better for the reasons they mentioned above.
