Indicate the method to use in studying the transversal changes of the dental arch.

• A. Snaghina
• B. Van der Linder
• C. Tweed- Merifeld analysis
• D. Pont

Answer: (D)

Studying transversal changes in the dental arch relies on a method that predicts and compares arch widths. Pont's index provides a practical way to do this: it uses the mesiodistal widths of the four upper front teeth to estimate the ideal transverse width at the canines and first molars. With these predicted widths, you can assess whether the arch is wider or narrower than ideal and track changes over time during treatment, making it especially useful for planning and evaluating expansion or constriction. Other methods in use focus more on sagittal relationships or incisor positioning, rather than predicting and monitoring transverse width, so Pont's approach is the most appropriate for studying transversal changes.
