Objective: This study aimed to examine the impact of repeated use of different implant impression analogs on the accuracy of the resulting impressions. Materials and Methods: Implant bodies from three brands (Group SA: Straumann, Switzerland; Group DA: Dio Implant, South Korea; and Group MA: Mode Implant, Turkey) were used to create master models. Five reference casts were then fabricated for each brand (n=5) from these master models. Ten impressions were taken from each reference cast using the same analogs, which were sterilized between each impression. Both the reference and working casts were digitized using a three-dimensional scanner. The working casts were aligned with their respective reference casts using software (Geomagic, USA). One-way ANOVA was used to compare the groups, while repeated-measures ANOVA was used to compare the impressions within each group. Multiple comparisons were performed using the Bonferroni, Tukey's HSD, and Tamhane's T2 tests, with significance set at p<0.05. Results: The RMS value for Group SA was 0.002 mm for the first impression, while the first impression RMS values for the other two groups were 0.04 mm and 0.03 mm, respectively. By the tenth impression, the RMS value for Group SA had increased to 0.08 mm, while the tenth impression RMS values for Groups DA and MA had reached 0.14 mm. Group SA demonstrated statistically significant differences after the third impression, whereas Groups DA and MA exhibited significant differences after the first impression. Conclusion: The results of this in vitro study demonstrated that repeated use of the same implant impression analog had a negative impact on impression accuracy.
