Summary
This study found that dedicated software for cervical vertebrae maturation (CVM) analysis shows high accuracy, comparable to manual methods. While slightly slower, the software provides reliable skeletal maturation assessment for orthodontic treatment planning.
Area of Science:
- Orthodontics
- Dentofacial Orthopedics
- Radiographic Analysis
Background:
- Skeletal maturation analysis is crucial for orthodontic treatment planning.
- The Cervical Vertebrae Maturation (CVM) method is a common technique.
- Manual CVM analysis can be time-consuming and operator-dependent.
Purpose of the Study:
- To evaluate the feasibility and accuracy of a new dedicated software for CVM analysis.
- To compare the software-based CVM analysis with traditional manual tracing.
- To assess the time efficiency of both analysis methods.
Main Methods:
- 100 lateral cephalograms from patients aged 7-21 years were analyzed.
- Cervical vertebrae C2, C3, and C4 were traced manually and using dedicated software.
- Analyses were performed by an experienced resident and an inexperienced student.
Main Results:
- High concordance was observed between software and manual analysis (94% for resident, 93% for student).
- Excellent interobserver concordance (99%) was achieved.
- Manual tracing was faster by an average of 28 seconds per tracing.
Conclusions:
- The dedicated CVM analysis software demonstrates excellent clinical performance and accuracy.
- The software offers a reliable alternative to manual CVM assessment.
- While manual tracing is quicker, the software's accuracy supports its clinical utility.
