Robotics in Dentistry

οδοντιατρικήαποκατάστασηImagine a dental practice, in which you have the perfect additive restoration during a single visit to the dentist and only in one hour!! It is no longer impossible since the digital technology in dentistry has made great strides in our days! The revolution of digital technology is found in the area of additive dentistry with the CEREC system (CEramic REConstruction) for creating dental restorations. Using CAD/CAM (computer-aided design and computer-aided manufacturing), this process allows dentists to construct, produce, and insert individual ceramic restorations directly at the point of treatment (chairside) in a single appointment, rather than over multiple appointments with labside work in between.



Most dental restorations require two or three visits to the dentist. This means that in the first visit, the dentist will prepare the tooth, meaning that the dentist will do the appropriate grinding and take the necessary measurements and then send them to the dental laboratory. Until the next visit, a temporary transitional restoration is placed on the tooth, which later on will be replaced by the permanent restoration, bonded with coarse adhesive to take its final position. In the third visit, after five to seven days, is the final welding. With CEREC the three visits shrink in one, which lasts from one to one and a half hours and the patient leaves the dental clinic with his tray. The difference between a CEREC tray and the conventional - classic metal ceramic one is that the grinding is very conservative and thus more healthy tissue of the tooth remains by providing the patient with a dental restoration that strengthens the tooth.ενθετο


During a chairside treatment, the dentist carries out all the steps, from digital impressions and computer-based construction of the restoration to the milling process, inside their office. The dentist uses an intraoral camera to take a photo of the preparation, the antagonist teeth, and the bite situation. Based on the images, the CEREC software creates a virtual model of the patient’s tooth situation. The dentist uses this model to construct the tooth restoration on the screen and then passes on the finished construction within the office’s network or sends it wirelessly to a milling machine. Depending on the type of restoration, it is then milled out of a color-matched ceramic block in just 6 to 15 minutes using diamond-coated milling units. The dentist can then add the finishing touches to the restoration by painting, polishing, and glazing it, before cementing it (the more traditional option) or adhesively integrating it, depending on the type of ceramic used.

CEREC technology makes it possible to produce and integrate ceramic restorations in a single appointment. Unlike other materials such as amalgam or gold, ceramic is more biocompatible and boasts tooth-like physical and aesthetic qualities. In addition, digital impressions are more comfortable for patients than traditional impressions.

By further developing the process, it was possible to reduce the amount of follow-up work and time-intensive occlusion adjustment that was often necessary in the past. According to studies, the ten-year lifespan of CEREC inlays polished and milled with the aid of a computer is not only significantly longer than that of gold inlays, but also exceeds that of individually laboratory-manufactured ceramic inlays. Further clinical studies reveal that the success rate of CEREC restorations is 95.5 percent following a period of nine years and 84 percent after 18 years

The digital mapping technology of CEREC that charts the inside of the patient’s mouth completely accurately and down to the last detail ensures that there is no issue with inaccurate dental impressions that lead the patient to experience discomfort with bulky molds and unnecessary debris in their mouth.
