Reliability of Bolton analysis evaluation in tridimensional virtual models.

Area of Science:

• Dentistry
• Orthodontics
• Digital Imaging

Background:

• Accurate assessment of tooth size discrepancies is crucial in orthodontics.
• Traditional methods rely on manual measurements from dental casts.
• The integration of 3D virtual models offers potential advancements in diagnostic accuracy.

Purpose of the Study:

• To evaluate the reliability of Bolton analysis performed on 3D virtual models.
• To compare the accuracy of virtual model measurements with traditional dental cast methods.

Main Methods:

• 56 pairs of dental casts from orthodontic patients were used.
• Manual measurements were taken using a digital caliper.
• Dental casts were digitized, and virtual measurements were obtained using specialized software.

Main Results:

• Statistical analysis showed no significant differences between virtual and manual measurements.
• P-values of 0.173 for total and 0.239 for anterior proportions indicate high agreement.
• The results demonstrate satisfactory concordance between the two measurement techniques.

Conclusions:

• Bolton analysis on 3D virtual models is a reliable diagnostic tool.
• Digital methods provide comparable accuracy to traditional dental cast analysis.
• Virtual models offer a viable and reliable alternative for orthodontic assessments.
