Abstract
Since 1984, many patients have been treated with Multiloop Edgewise Archwire (MEAW) Technique and diagnosed with ODl (Overbite Depth Indicator) and APDl (Anteroposterior Dysplasia Indicator) by the authors. 234 samples of them were selected randomly for the statistical analysis (age, sex, Angle´s classification, treatment period, extraction, ODI etc.). Especially, ODI was analysed statistically and its application methods were reviewed. The results and conclusions were as follows: 1. On the 150 patients with normal overbite, the mean values of Class I, II, III malocclusion were 67.5°, 72.2° and 59.0°. They were significantly different on the level of p<0.01. 2. In normal overbite samples, ODI decreased with the increase of APDI and the correlation coefficient was - 0.54. It seems that this result reflects the characteristics of AB to mandibular plane angle. 3. The regression equation was Y=-0.57X + 114.64, where X is APDl and Y is ODI. In cases of small or large APDI, it seems to be absurd that the patient´s ODI is compared with the mean ODI to differentiate diagnostically the open bite or deep bite tendency from the normal.
