The SNA angle decreased gradually during the treatment, whereas the SNB angle stayed almost the same, reducing the ANB angle
Post-treatment Cephalometric analysis showed that ANB angle
changed from Class III skeletal to Class I (ANB - 1-2 degrees) and WITS appraisal also changed 2 mm (5-3 mm).
Objective: To correlate cephalometric values of ANB angle
and Wits appraisal in patients reporting to AFID.
Lateral cephalograph was taken to measure the ANB angle
The following parameters were analyzed as the indicators of the sagittal position and length of jaws: the angle of maxillary prognathism, the angle of mandibular prognathism, ANB angle
as an indicator of sagittal jaw relations, maxillary length (Asnp), and the length of the mandible (Gn-Go).
Moreover, individuals with Class II division 1 dental-relationships with mandibular deficiency present an open mandibular plane, decreased SNB angle, increased ANB angle
and positive AO-BO.
We evaluated the ANB angle
and condilar vertical high, we used the Habets et al.
The lateral cephalometric films of all patients were traced and the anterior-posterior skeletal relationship of the maxilla and mandible was classified as skeletal Class I (ANB angle
between 0 and 4), Class II (ANB angle
5 or more), and Class III (ANB angle
less than 0) using the measurements of the Witz and ANB angle
They were divided in Class I or Class II skeletal patterns, according to the ANB angle
and WITS appraisal.
The skeletal discrepancy between maxilla and mandible improved as reflected by the improved ANB angle
The existence of significant differences in the relationship between the maxilla and the mandible as determined by the ANB angle
and by the linear projection of points A and B in a true horizontal line has been observed.
Skeletal type was determined based upon the ANB angle
and Wits, which indicates the positional relationship of the maxilla and mandible.
