Objective: This study compared the positional changes in mandibular condyle before and after treatment with functional appliances. Study Design: Comparative, cross sectional study. Place and Duration of Study: Armed Forces Institute of Dentistry, Rawalpindi, from Dec 2016 to Dec 2018. Methodology: In this study patients opting for orthodontic treatment in Armed Forces Institute of Dentistry (AFID) and falling on our inclusion criteria were selected and were compared for pre and post treatment positional changes of condyle associated with twin block/bionator therapy, by comparing lateral cephalometric changes. Results: Age range was 11 years to 15 years, with mean of 12.02 ± 1.05. Changes in condyle position with respect to midface were found to be significant with a mean of 2.20 ± 2.97, p<0.001 between pre and post treatment values. Changes in condyle position with respect to anterior cranial base were also significant reported by a mean pre and post treatment difference of 2.09 ± 1.23, p<0.001. Orientation of long axis of condyle with posterior cranial base was also significantly changed with a mean difference of 5.11 ± 4.19, p<0.001. Conclusion: Condyle was displaced posteriorly with respect to anterior cranial base as well as midface. Vis-à-vis the orientation of long axis of mandibular condyle, it attains a more upright position post treatment, with respect to cranial base.
