The lowest radiant exitance was 1149 mW/cm² and the highest was 1257 mW/cm².

Resin-based cement was then applied. After 24 hours, the blocks were sectioned to obtain bars for testing.

Two years later, the fit accuracy of the DMLS prosthesis and patient satisfaction were re-evaluated. The accuracy of fit in the maxillary RPD with the DLMS manufactured metal framework showed better results in all areas except areas of rests (457 vs. 421 μm) and the major connector (850 vs. 512 μm). The mandibular RPD with DLMS manufactured metal framework showed only in the areas of the reciprocal arm and major connector better fit accuracy compared to the conventional RPD.

However, both materials showed insignificant wear after 6 months of overdenture use.
