Abstract

Objective: To evaluate the accuracy of data obtained from two intraoral scanners and models fabricated using two 3D printers for maxillary unilateral partial edentulism in vivo.


Methods: The working models were obtained from 20 different participants. The reference datasets were acquired using irreversible hydrocolloid impression material. Two distinct intraoral scanner systems were evaluated: Cerec Omincam (Dentsply Sirona Dental GmBH, Salzburg, Austria) and 3Shape Trios (3Shape Dental Systems, Copenhagen, Denmark). Additionally, data extracted from intraoral scanners of cast models with four unilateral missing teeth in the  posterior region of the maxillary arch, classified as Kennedy Class III, were obtained using 3D printers with two different production techniques. The Solflex 650 (W2P, Klosterneuburg, Austria), a 3D printer utilizing DLP technique, used Varseo Wax resin (Bego, Bremen, Germany), while the AccuFab-L4D (Shinning, Hangzhou, China), a 3D printer utilizing LCD technique, used Shinning brand resin. Deviation analysis was conducted to assess accuracy using Geomagic 3D image processing software. Statistical analysis was performed using t-test and Kruskal-Wallis test (P < 0.05).


Results: No significant differences were observed in the accuracy of digital impressions among intraoral scanners and 3D printers. However, a significant difference was noted in the z coordinates across all groups where digital production techniques were applied. The highest accuracy value was observed in the model produced with the Trios intraoral scanner and AccuFab-L4D 3D printer, while the lowest accuracy value was found in the model produced with the Cerec intraoral scanner and Solflex 650 3D printer.


Conclusion: The cast models obtained with intraoral scanners and 3D printers in the Kennedy Class III cases demonstrated potential as viable alternatives to study models obtained through conventional techniques.
