To assess trueness of IM, MIL, and stereolithog. printed denture bases after manufacturing, hydrothermal cycling, and microwave sterilization. 16 Edentulous maxillary plaster models were poured using silicone mold and digitized by means of desktop scanner. For group IM, 16 denture bases were injection molded. MIL and SLA, denture bases were virtually designed and manufactured referring to digitized data. A total of 48 samples were scanned 1) after manufacturing, 2) after hydrothermal cycling three as well as 4) six cycles of microwave sterilization for 6 min each at 640 W. The 3D surface deviation of the total intaglio surface, the palate, the alveolar ridge, and the border seal region was evaluated on basis of RMSE and pos. and neg. mean deviations with inspection software. In comparison, IM showed increased, mainly pos., deviations at border seal. SLA presented highest total RMSE with increased neg. deviations, likewise at the border seal. In contrast to SLA, no differences between IM and MIL were measured after hydrothermal cycling. Following microwave sterilization, the trueness of SLA was higher compared to IM and MIL with no differences between MIL and IM. Distortion of IM and MIL was measured after the 3rd cycle with no further changes observed Subtractive manufacturing of denture bases results in the highest trueness, followed by IM and SLA. IM and SLA, hydrothermal cycling did not affect MIL. SLA printed denture bases remained dimensionally stable after microwave sterilization.
