One of the most pressing problems of dentistry is to eliminate long and unpleasant procedures that are keeping patient tied to a chair for hours. Making dental crowns is a part of interventions we do in dental practice Cvejanovic, and each patient has had to undergo a very unpleasant procedure of taking teeth print with plaster and then waiting a few days for the crowns.
Fortunately, that is in the past now!
No more painful mouth pulling for taking prints, no more double and triple tests and corrections of crowns, no more sickness which produces plaster in the mouth, no more waiting!
Dental practice Cvejanovic included in its arsenal of modern equipment phenomenal CEREC (CEramic REConstruction) machine, which enables the digital production of crowns and taking teeth prints on the spot in the office for only half an hour! In addition to the crowns, with CEREC method are also made fillings, bridges and ceramic veneers.
The procedure of making a crown begins with scanning, which is completely non-invasive and takes only a few seconds, and the future model of the tooth and crown is possible to see on the computer screen immediately. In case that we suspect that the scan was not complete or that the patient was moving, it is easy to repeat the process, while with the traditional method repeated taking of tooth print represents a remarkable effort and is physically very uncomfortable for both doctors and patients.
Furthermore, using software that is part of the CEREC system, milling machine makes the crown of ceramic cube in front of the eyes of a patient for a few minutes, despite earlier procedure when model was sent to the laboratory for making crowns (waiting several days) or crowns were made in dental office (waiting a day or two), whereby the patient often had only minor parts of the teeth in the jaw that are designed to wear the crowns while waiting, which is psychologically the most uncomfortable part of the treatment, whereas installing an implant patient could receive temporary crowns, but it constituted an additional cost.
When a crown comes out of the milling machine, it is accessed to its processing and polishing, after which it is immediately cemented in the mouth of a patient, and the entire process from scanning to the first bite lasts only 30 minutes.
Besides comfort, mental peace and saving money, the advantage of making crowns with CAD CAM CEREC system is in incredible precision of fiting any dental part or dental crowns, veneers and ceramic inlays. Consequently with procedure of digital scanning and modeling unnecessary phases in the making of crowns are skipped and thus there is less room for a mistake. No matter how good dentist is, it is likely that the crown made in a standard way will not be in perfect shape but just about perfect, ie. it will be functional, but will not be maximally comfortable, efficient and beautiful, while the CEREC method achieves absolute perfection.
The next significant advantage of CAD CAM CEREC system is that dental crowns are made full ceramic or from the finished ceramic blocks. As laptops and mobile phones whose chassis are from a single piece of aluminum, so the monolithic ceramic compensations are more apreciated, in which the entire dental crown is of the same piece of ceramic, far more stronger than those made by combining ceramics and metal, or ceramics and zirconium. The relation between the two materials is the weakest link in the crown and there is where the cracking and chipping of ceramis could happen, which is why in modern dentistry compensations are increasingly made full ceramic.
The only restriction CEREC technology is an occasional need to paint a crown in a different color than the original ceramic cube, but this is a process that lasts only one day, and is required only in the most demanding aesthetic surgeries and for teeth in the front zone. Also, it is not possible in any case to create a crown for implant in the CEREC machine, although this technique significantly accelerates making of crowns for complete implanting work, because it reduces to a minimum the number of crowns that have to be done manually.
