dc.description.abstractPurpose: To evaluate the effect of material thickness and coffee thermocycling on the optical properties of definitive resin-based materials created via additive manufacturing (AM) and subtractive manufacturing (SM). Materials and Methods: Specimens were prepared in three thicknesses (1, 1.5, and 2 mm) from three AM (3D-CB, 3D-TH, and 3D-CT) and two SM (G-CAM and VE) resin-based materials (n = 15 per material and thickness combination). Color coordinates of each specimen were measured after polishing and after 10,000 cycles of coffee thermocycling. Color differences (?E00s) and relative translucency parameter (RTP) values were calculated. After logarithmic transformation, ?E00 values were analyzed with two-way ANOVA, while RTP values were analyzed with generalized linear model test (? = .05). Results: 3D-TH had the highest pooled ?E00 and G-CAM had the lowest (P ? .004). 3D-CB had higher pooled ?E00 than VE and 3D-CT (P ? .002). For the SM group, the 1.5-mm and 2-mm 3D-CT specimens and 1-mm 3D-TH specimens had lower ?E00 than 1.5-mm and 2-mm 3D-TH specimens (P ? .036). Most of the AM specimens and 1-mm VE specimens had higher ?E00 than 2-mm G-CAM specimens (P ? .029). Further, most AM specimens had higher ?E00 than 1.5-mm G-CAM specimens (P ? .006). RTP values increased in order of 3D-CT, G-CAM, VE, 3D-CB, and 3D-TH specimens (P < .001). Increased thickness and coffee thermocycling mostly reduced RTP (P < .001). Conclusions: 3D-TH typically had higher color change values than SM specimens, while G-CAM typically had lower color change values than AM specimens. Only the 1.5-mm and 2-mm 3D-TH specimens had unacceptable color changes. Thickness and coffee thermocycling mostly reduced the translucency. ©2024 by Quintessence Publishing Co Inc.
