Summary
CEREC Ortho software provides accurate and reliable digital dental models for orthodontics, though manual measurements show higher correlation. This digital tool offers time efficiency for diagnosis and treatment planning.
Area of Science:
- Orthodontics
- Digital Dentistry
- Biomedical Engineering
Background:
- Digital models are emerging as alternatives to traditional plaster models in orthodontics.
- Evaluating the performance of digital impression systems is crucial for clinical adoption.
Purpose of the Study:
- To assess the accuracy, reliability, and efficiency of CEREC Ortho software for orthodontic measurements.
- To compare digital measurements from CEREC Ortho software with conventional manual measurements.
Main Methods:
- Twenty conventional plaster models were scanned using CEREC Ortho software by three examiners.
- Linear measurements (transverse, anteroposterior, vertical) were acquired digitally and compared to manual caliper measurements.
- Intraexaminer and interexaminer reliability were evaluated.
Main Results:
- Statistically significant differences were found between digital and manual measurements, but most were clinically acceptable.
- Manual measurements exhibited a higher correlation compared to software-derived measurements.
- CEREC Ortho software scanning averaged 2.67 minutes, while manual measurements were faster.
Conclusions:
- CEREC Ortho software measurements show acceptable accuracy and reliability in laboratory settings.
- The software can serve as a reliable complementary tool for orthodontic diagnosis and treatment planning.
- This study provides early insights into the accuracy, reliability, and efficiency of CEREC Ortho software.
