Reliability and time-based efficiency of artificial intelligence-based automatic digital model analysis system

Area of Science:

• Dental diagnostics
• Digital dentistry
• Orthodontic analysis

Background:

• Intraoral scanners are increasingly used in orthodontics.
• Digital models offer potential advantages over traditional methods.
• Evaluating the efficiency and accuracy of digital analysis is crucial.

Purpose of the Study:

• To compare the reliability, reproducibility, and time efficiency of automatic digital (AD) versus manual digital (MD) analysis of intraoral scan models.
• To assess differences in key orthodontic measurements between the two methods.

Main Methods:

• Two examiners analyzed 26 intraoral scanner records using both MD and AD methods.
• Bland-Altman plots assessed tooth size reproducibility.
• Wilcoxon signed-rank test compared model analysis parameters and time.

Main Results:

• Automatic digital analysis showed smaller measurement deviations (0.08 mm vs. 0.15 mm).
• AD analysis was significantly faster (0.56 min vs. 8.62 min).
• Significant differences in 12-tooth and arch perimeter measurements were found between AD and MD methods (P < 0.001).

Conclusions:

• Automatic digital analysis offers superior reproducibility and time efficiency.
• Clinically significant differences in measurements necessitate distinct application of AD and MD methods.
• AD and MD analyses are not interchangeable for orthodontic modeling.
