He had a maximum opening of 52mm and lateral movements of 12mm to the left and 11 mm to the right. Radiographic Analysis The Panoramic radiograph showed a full complement of teeth. (Fig. 3) His third molars were in early formation, but the lowers appeared to be impacted horizon-tally. It was explained to the parents that the patient might need his third molars removed at a later date. The Cephalometric Radiograph was traced digitally, employing the Carapezza Analysis. (Fig. 4) His GO-GN to SN was 31°. His Y axis was 67°, indicating a mesocephalic growth pattern. The SNA was 81°, SNB 76° and ANB at 5°.
