When performing dental work of high quality, the team work implies a close cooperation between a doctor of dental medicine and dental technician. In fact, the prerequisite for producing results of the highest quality is a close cooperation between the two; ideally, in the same working area so that all the procedures could be performed with the highest precision and in the shortest possible time period.
Our dental lab is equipped with modern diagnostic technology and modern CAD/CAM systems like Cerec and KaVo Everest.
Our dental technicians are highly trained to, working as a team with doctors of dental medicine, contribute both to the aesthetic and functional part of the procedure, so that they could achieve optimal results while reducing as much as possible the amount of time needed to do the procedure.
This technology represents a computer simulation of the design itself and production of dental prostheses (inlay, onlay, solo crowns and bridges). In the late eighties of the twentieth century, when CAD/CAM systems arrived to the dental studios, they soon became a largely used technology, mostly because of their speed in producing dental prostheses. With this technology there is no need to take classic dental impression using different imprint materials, but the entire process of taking dental impression is done by using a special camera. In that way, the doctor can monitor the process by herself without the necessity of involving the dental laboratory. All these things significantly reduce the duration of the procedure, and also reduce the number of steps of the production of dental prostheses which, finally, has as a direct result a reduced number of possible mistakes. Thanks to this technology we are able to work faster, with more efficiency and with more quality. In a time period of two hours we can make and place a non-metal crown or inlay – onlay inside our patient’s mouth, while it will take only a day for a more complex production of a smaller bridge. Our machines are so sophisticated that it enables us to spot and remove any possible mistake during tooth-drilling; also, it with the help of it we produce ideally shaped prostheses, a perfect fit between teeth and coordinated occlusal morphology.
The restoration is being cut in special cutters which are a constituent part of every CAD/CAM device. The process normally does not take too much time and restoration can be done in a time period from ten minutes to an hour, depending on a type of the device and replacement.
MATERIALS FOR DENTAL MILLING MACHINES
In dental prosthetics, in the procedure of milling, we normally use all-ceramic of great thickness. There are factory-made ceramic blocks that are inserted in the cutters where they are shaped. All-ceramic, as the name itself suggests, does not require a metal construction as a support. It is thick enough to take the pressure without the support of another material, such as metal or gold. This material is almost entirely chemically inert and it is extremely bio-compatible. At the same time, it is an abrasion resistant material, its colour is stable and it has very good aesthetic qualities, which is particularly important nowadays. Besides being an excellent material for accomplishing lifelike appearance when it comes to the colour of the crown, the transition from the base of the tooth and the ceramic crown becomes completely invisible, which makes it possible for the dentist to place the crown on the visible part of the tooth. Today, aesthetics has become an important aspect of every procedure in dental medicine. Doctors of dental medicine and dental technicians are trained for producing ceramic restorations are not, in any aspect, inferior to the adjacent teeth and antagonists.
Materials of highest quality and the best production methods
CEREC: It is one of the oldest CAM/CAD systems which appeared on the market in the beginning of the 1980s. The acronym CEREC comes from the full name of the device – “Chairside Economical Restoration of Esthetic Ceramics”. The manufacturer is the company named Sirona and there has been a couple of series of the product. The latest Cerec Omnicam system with a 4.3 software occupies the very top spot in the production and in the technological quality of the product. CEREC system has the possibility of adjusting the tooth to all the dimensions and achieving the perfect occlusal contact between it and its antagonist. It is, therefore, for all the right reasons, called CEREC 3D system. The very process of the production is so perfect that, basically, every possibility of making a mistake has been removed.
KaVo EVEREST SYSTEM:
This system is similar to CEREC and it also uses an optical impression using an intraoral camera. It is necessary to take a normal impression using the standard impression materials after which the system scans the model. The very process of the scanning is very detailed and the system records 20, 000 measuring points which serve as a basis for the production of the prostheses. With the help of Everest system it is also possible to produce crowns, bridges, inlays, onlays and aesthetical dental veneers with high precision. Depending on the need, prostheses can be also made from different types of strengthened ceramic materials.
When performing work on implants it is necessary to do a temporary prosthesis or a temporary bridge on the implant the very next day after the surgery. It is only possible with such a team work in the same area where the dental studio is.
