초록

Purpose: Length measurement from maxillary anterior teeth root tip to nasal floor is incorrect in panoramic radiography. Comparison of cone beam computed tomography (CBCT) and panoramic radiography should be helpful in determining the vertical length.
Methods: Sixty nine patients were taken CBCT and panoramic radiography of the maxillary anterior. First measurement is length of parallel lines from the central incisor and lateral incisor root tip to nasal floor on CBCT. Second measurement is length of perpendicular lines from the central incisor and lateral incisor root tip to nasal floor on CBCT. Third measurement is length from the central incisor and lateral incisor root tip to nasal floor on panoramic radiographys.
Results: In the first measurement of the maxillary central incisors, an average of 11.36±2.49 mm in males and 10.49±2.17 mm in females. In the second measurement of the maxillary central incisors, 10.41±2.42 mm in males and 9.18±2.08 mm in females. In the third measurement of the maxillary central incisors, 10.71±2.20 mm in males and 9.27±2.10 mm in females. In the first measurement of the maxillary lateral incisors, an average of 13.40±2.04 mm in males and 11.96±2.20 mm in females. In the second measurement of the maxillary lateral incisors, 11.25±1.82 mm in males and 10.06±1.68 mm in females. In the third measurement of the maxillary lateral incisors, 11.47±2.01 mm in males and 10.13±1.70 mm in females.
Conclusion: The vertical length from root tip to nasal floor was longer in male than female (P＞0.05). First measurement was longer than third measurement (P＜0.05). This is the actual placement of the implant site measured on the vertical length than the length of the panorama means that there are a few more free. The first measurement was longer than 114% over the third measurement.
