Özet

Statement of Problem: Various digital technologies are used in the design and fabrication of temporary restorations; however, the clinical success of these approaches relies on how accurately the physical restorations replicate the initial virtual designs. PURPOSE: This clinical pilot study aims to evaluate the dimensional accuracy of temporary laminate restorations fabricated using a fully digital workflow. Two different digital smile design software programs: Smile Creator (Exocad) and SmileCloud were used to generate 3D designs, which were subsequently fabricated with SLA 3D printing technology. The objective was to compare the physical restorations with their corresponding virtual 3D designs. MATERIALS-METHODS: Five participants with non-ideal anterior maxillary esthetics were selected. For each subject, intraoral and extraoral photographs, along with digital scans, were obtained. Smile designs were created using SmileCloud and Smile Creator software. The designs were aligned with STL files and finalized using Exocad DentalCAD. Temporary restorations were fabricated using SLA 3D printing. Dimensional measurements were taken at specific landmarks: incisal edge to gingival margin, mesio-distal widths of central and lateral incisors, and the distance between distal margins of maxillary canines. Two independent examiners performed the measurements using virtual and digital calipers. Intraoral fit was also clinically checked. Statistical analysis was performed using the Shapiro-Wilk test for normality and Wilcoxon signedranks test for non-parametric comparisons (p < 0.05). RESULTS: No statistically significant differences were found between the 3D virtual designs and printed restorations for either software (p > 0.05). However, a significant reduction in intercanine distance was observed when comparing SmileCloud’s 2D designs with their corresponding 3D models and printed restorations (p < 0.05). CONCLUSION: Both software demonstrated acceptable accuracy in producing 3D-designed temporary restorations. However, discrepancies in 2D-based designs highlight the limitations of 2D planning and the importance of 3D evaluation for dimensional accuracy.
