Which biometric study method determines the transverse diameters of the jaws?

• A. Snaghina
• B. Van der Linder
• C. Tweed-Merifield total space analysis
• D. Pont

Answer: (D)

Transverse dimensions of the jaws are about the width of the dental arches. Pont’s biometric method is the one that directly estimates these widths by relating the sizes of the teeth, particularly the anterior teeth, to the arch width. In practice, Pont’s approach uses tooth-size measurements to predict the ideal transverse dimensions of the arches, helping determine whether expansion or other treatment is needed to achieve proper jaw width relationships. Other methods listed are more about space or alignment within the arch rather than measuring the width across the arch. Tweed-Merrifield total space analysis focuses on the overall space required in the arch for proper alignment and is more about sagittal considerations and crowding decisions. The remaining named methods serve different analytic purposes in biometric assessment and do not specifically determine the transverse diameters of the jaws.
