Abstract

Aim This study evaluated the dimensional stability of maxillary dental casts used for a 3-unit fixed partial denture across four build orientations (0°, 30°, 45°, and 90°).
Material and method An upper jaw typodont with tooth preparations for a posterior 3-unit fixed partial denture was scanned by using an industrial scanner. The resulting scan file was nested with different orientations (0°, 30°, 45°, and 90°) and the casts were additively manufactured by using a digital light processing 3-dimensional (3D) printer (n = 7). Subsequently, all additively manufactured casts were scanned with the same scanner at 3 different time points (after fabrication, 1 month after fabrication, and 3 months after fabrication) and the deviations at the fixed partial denture region were assessed with the root mean square (RMS) method. Statistical analysis was performed using a generalized linear model at a significance level of α = 0.05.
Results The build orientation and the time point significantly affected the RMS values (P<.001). However, the interaction between the main factors did not affect the RMS values (P=.808). Among tested build orientations, 0° led to the lowest and 90° led to the highest RMS (P≤.001). In addition, casts with 30° build orientation had lower RMS than those with 45° (P<.001). Tested casts had their lowest RMS after fabrication (P≤.006).
Conclusion Dimensional stability of tested casts decreased with increased build orientation. The dimensional stability of tested casts decreased 1 month after fabrication and did not change 3 months after fabrication.
