Objective: To assess the sagittal skeletal changes with Beta angle in patients treated with Frankel II appliance using Dolphin Imaging Software.
Materials and Methods: Pretreatment (T0) and post-functional therapy (T1) lateral cephalograms of 30 patients (23 females and 7 males, Age range of 8 to 12 years) treated with Frankel II appliance in digital form were uploaded in Dolphin Imaging Software (Version 11.95). The position of each landmark was located digitally in the software and recorded. Pre- and post-treatment Beta angle for each patient was calculated by the software. The mean difference between T0 -T1 was compared to assess the effects of the Frankel II appliance and analyzed. Paired t-test was used to compare the statistical differences between the parameters.
Results: Intra-group comparison of the Beta angle measurements revealed that there existed a significant difference between the groups (p<0>
Conclusion: Beta angle increased significantly following Frankel II therapy suggesting considerable improvement in skeletal discrepancy. The Frankel II appliance can be utilized in young children with class II malocclusion to treat maxillomandibular sagittal problems. Beta angle can also be used with other parameters to analyze sagittal skeletal malocclusions.
