By using the measurements offered by White (op. cit.) or using Brader arch forms as templates (avail-able from author upon request), clin-icians can occlude these occlusal 2-D images to effect more accurate tooth size discrepancy measurements and avoid the inherent imperfections of the Bolton Analysis.

Fig. 3: Adolescent CL I patient with a congenitally missing mandibular central incisor, anterior and posterior X-bites, retained primary incisor, midline deviation and a maxillary arch length discrepancy. Note the occlusogram with the arrow pointing to a superabundance of right poste-rior molar overjet, which will result in a large anterior overjet and overbite and require some maxil-lary anterior interproximal enamel reduction (IER).
