Indicate the method of the biometric model study for assessing the development of dental arches in the transverse plane.

• A. Korkhaus
• B. Pont
• C. Snaghina
• D. Tweed - Merrifield

Answer: (B)

When studying how the dental arches develop in width, you need a method that directly quantifies transverse dimensions on study casts. Pont’s method is designed for that purpose, providing measurements of arch width (such as intercanine and intermolar distances) on biometric models and allowing comparison of transverse development over time or between groups. This makes it the most appropriate choice for assessing changes in the transverse plane. Other methods emphasize different aspects: Korkhaus offers a broader occlusal analysis, Tweed–Merrifield focuses on incisor angulation and sagittal relationships, and Snaghina isn’t a standard reference for transverse biometric assessment.
