| 内容記述 | Arch length discrepancy is one of the most important factors in orthodontic diagnosis. This is considered to involve two parts of anterior and posterior discrepancy. Anterior discrepancy is defined as a difference between available arch length which is obtained by measuring the arch perimeter mesial to the first molar and total tooth size of the second premolar to the other side. Recently, posterior discrepancy has been considered a relevant measurement in orthodontic practice. Posterior discrepancy can be defined as a difference between available arch length posterior to the first molar and total tooth size of the first, second, and/or third molars. However, analysis of posterior discrepancy has not been established. This study was to assess the analysis of posterior discrepancy on panoramic image, in comparison with the actual length of a human dry skull. Fifty human dry skulls were used in this study. Two dental panoramic image photographs of the dry skulls with and without metal wire were taken for each skull. Measurement of the actual length of all dry skulls and measurements of the panoramic image of the skulls were measured on both sides of the upper and lower jaws. Five different methods of measurement were tested on panoramic image on both sides. The best measurement of upper posterior discrepancy was obtained by calculating the distance between perpendicular to occlusal plane from half the arc of Ptm and most posterior teeth to the distal line of the second molar. The best measurement of lower posterior discrepancy was obtained by calculating the distance between the intersection points of the anterior ramus line and the horizontal line through the widest points of the second molar and the distal line of the second molar. | |||||||
