Are you uncertain about the fast fabrication rate of same day crowns for your teeth? Below are the major steps that are followed to produce your restorations on the same day.
Previously, impression trays were inserted into a patient's mouth to get impressions of the teeth so that restorations could be designed and fabricated. That process was often unpleasant because it required a patient to bite the tray multiple times. Today, digital technology has made it possible to simply scan the teeth and get digital impressions. These impressions form the basis of what happens in the next step.
The data collected during the scanning process is fed into custom software to generate several designs of crowns that your dentist can select from. This step is one of the main reasons why you can leave the dentist's office with your new crowns in place. The digital designs can be ready for the fabrication process to start in a few minutes after the dentist has made his final design selection.
Grinding and Milling
The design software forwards the final design of your crowns to the grinding and milling unit so that crowns can be fabricated to the exact specifications formulated from the scans of your teeth. The grinding and milling process is so accurate that the completed crowns have a smooth surface.
Sintering and Finalisation
The final step of the fabrication process involves sintering and glazing the crowns in a furnace within the dentist's office. This process is also controlled by the software that designed the crowns. Thus, there is no risk that the crowns will be heated excessively.
Crown Installation and Scanning
The dentist now gets the completed crowns and installs them on your teeth. This is done when the crowns have cooled after the sintering process. They then scan your mouth again to confirm that the finished crowns fit you in accordance with the original scan specifications. The data is saved and you are free to head home with your new crowns.
It is evident that the process of making new dental restorations, such as crowns, has now been fastened by the availability of advanced technology. The process is so fast that you only need one local anesthesia injection for the entire procedure. Talk to your dentist in case you have any other concerns about this procedure. They will also advise you about the suitability of the process based on your dental needs.
