Purpose: This study aimed to evaluate the clinical acceptability of various cement space settings on the marginal and internal fit of cobalt–chromium (Co-Cr) copings fabricated by additive manufacturing. Methods: The maxillary right first molar was used as the master model (AG-3, Frasaco). After scanning the master model using a dental three-dimensional scanner (E3, 3Shape), the stereolithography file was created with different cement space settings of 0, 30, 50, and 100 μm using computer-aided design software (Dental System 2018-1 ×64, 3Shape). A total of 40 single copings were made with the selective laser melting (SLM) method using Co- Cr alloy and were divided into four cement space groups with 10 specimens each. The marginal and internal fit of the four groups were measured using the silicone replica technique. The measurement points were categorized into margin, axial wall, and occlusal. Statistical analyses were performed by the Shapiro–Wilk test, one-way analysis of variance, and Tukey’s honestly significant difference test (α=0.05). Results: In the cement space 50 μm group, the marginal and internal fit was found to be overall superior to that of the cement space 0, 30, and 100 μm groups, and the margin and occlusal points demonstrated significant differences, except the axial wall points. Conclusion: In this study, a cement space setting of 50 μm is recommended to achieve optimal marginal and internal fit for Co-Cr copings fabricated using the SLM technique.
