Shortcomings of anb angle
Splet25. nov. 2016 · ANB values are in a range between −4.2° and 9.0°. It was observed that ANB values tend to decrease as growth occurs in every group. For Class I, an average ANB decrease of 1.5° was observed between the stages CVS 1 and 6. In Class II, the reduction was 0.7°, and 3.1° in Class III individuals [ Table 3 and Figure 1 ]. SpletBecause the ANB angle can vary without any marked abnormalities in the sagittal jaw relationship, the use of the so-called normal limits for the ANB angle is not justified. It …
