Long term use of intraoral optical scanning methods in the production of fixed dental restorations is one of the recognizable characteristics of Cerec® 3D CAD/CAM system. The aim of this study was to determine the degree of precision of ceramic crowns made by the technique of intraoral optical Cerec®3D scanning system. Material and methods The crowns prepared for the experimental group were scanned by the intraoral optical Cerec® 3D scanning system. In the control group, the porcelain-fused-to-metal crowns were made according to the conventional methodology. The crown accuracy was examined by measuring the size of the marginal gap between the crown and the marginal adaptation zone using the scanning microscope. Discussion The results showed that there was a difference in the accuracy between crowns of the experimental (50.27±31.50 μ) and the control group (132.92±53.21 μ). Conclusion The crowns made using the methods with intraoral optical scanning Cerec 3D system showed a high and cli...nically acceptable degree of accuracy.
Dugogodišnja primena metoda intraoralnog optičkog skeniranja u postupku izrade fiksnih zubnih nadoknada jedna je od osobenosti po kojoj je prepoznatljiv sistem Cerec®3D CAD/CAM. Cilj rada je bio da se utvrdi stepen preciznosti keramičkih kruna izrađenih primenom tehnike intraoralnog optičkog skeniranja sistema Cerec®3D. Ispitivanje je sprovedeno u okviru eksperimentalne grupe kruna u čijoj je izradi primenjena tehnika intraoralnog optičkog skeniranja sistema Cerec®3D. Metalokeramičke krune izrađene konvencionalnom metodologijom bile su kontrolna grupa. Preciznost kruna ispitivana je merenjem veličine marginalnog zjapa između ruba krune i demarkacije preparacije pomoću skenirajućeg elektronskog mikroskopa. Rezultati istraživanja pokazuju da postoji razlika u preciznosti kruna eksperimentalne (50,27±31,50μ) i kontrolne grupe (132,92+53,21μ). Krune izrađene primenom metoda intraoralnog optičkog skeniranja sistema Cerec 3D pokazuju visok i klinički prihvatljiv stepen preciznosti.
