The willingness of the patient to cooperate.The quality of the impression material being used.This in itself depends on a number of factors including: The perfect dental crown relies on the complete accuracy of the impression being taken. If you think about it for a minute – there are too many variables that can cause a lab-made crown to be incorrect or inaccurate.įirstly there is the messy business of impression taking. One of the biggest issues with traditional crowns over CEREC crowns is accuracy. CEREC crowns – pinpoint accuracy, every time. Once milled, the CEREC crown is then taken, fitted, and polished up to match your existing teeth – all on the same day. From there, a 3D milling machine located at the dental practice uses that image to cut out or ‘mill’ an exact replica of the patient’s dentition. During a quick and comfortable process, it takes a 3D image of the area which is then fed into a computer program. On the contrary, with CEREC crowns any impression is taken digitally using a scanner. In some instances, for patients with a low gag reflex, it can also be a really unpleasant experience. This can be both messy and uncomfortable. For patients, this means having to bite down on gooey alginate for a lengthy period of time. Usually, lab-manufactured crowns require you to have a physical impression. In a word, no! However to see the other advantages this type of crown has, we really need to understand the processes involved. While CEREC crowns are a speedy alternative, is efficiency really the only advantage of the CEREC crown system? Using the latest CAD/CAM technology and state-of-the-art milling equipment, patients receive a perfect bespoke crown in just one single visit! The biggest advantage of a CEREC crown is that a restoration can be designed and milled right here in our dental clinics. Although some patients may receive a temporary crown while they wait, it isn’t always an ideal situation. Understandably, this can take several weeks for the lab to receive the impression, make the tooth and send it back. Normally, impressions are taken and the cast is sent off to a centralised dental laboratory to be made into a fully-functioning, lifelike tooth.
With CEREC crowns, however, the entire process can significantly be shortened. However, anyone who has had a standard crown fitted will know hat it can be a time-consuming process that usually takes several or more weeks to complete. Typically, both traditional and CEREC crowns are ideal for teeth which are heavily decayed or damaged and are also commonly used as routine finishes for procedures such as root canal therapy or dental implants. Unlike inlays and onlays which fit into, and onto parts of the tooth to add further protection, dental crowns cover the entire tooth. It’s true that the creation and placement of a custom-dental crown is one of the most commonly performed procedures in dentistry today. A Chairside Economical Restoration of Esthetic Ceramics or – CEREC crown for short – is a relatively new field of dentistry that allows the dentist to produce evermore natural, and functional ceramic crowns in order to give patients a better, lifelike smile.
