Implication

In vitro study evaluates the impact of implant configuration on the accuracy of digital impressions, highlighting significant distortion differences among setups.

Key Points

  • This study aims to evaluate how different spatial configurations of implants affect the accuracy of complete-arch digital implant impressions.
  • In vitro study with three mandibular models representing different implant spatial configurations: closely spaced, widely distributed, and angulated implants.
  • Seven intraoral scanners were assessed through ten scans per model, generating 210 STL datasets for analysis.
  • Trueness was measured using root-mean-square deviation values with two-way ANOVA for statistical analysis.
  • Significant differences in RMS deviation values were found among scanners (p < 0.001) and implant configurations (p < 0.001).
  • Closely spaced implants showed lower RMS deviation, while widely distributed implants exhibited the highest deviations across most scanners.
  • Primescan 1 and Primescan 2 had lower RMS values, demonstrating better performance in complex configurations.
