A Retrospective Evaluation of Forsus Fatigue Resistance Device (FRD) Therapy on Sagittal Airway Dimensions.
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 12
Abstract
Airway dimension is closely related to maintenance of a proper breathing pattern. The aim of this study is to investigate how Forsus FRD affects upper airway dimensions. Pre-and post-treatment lateral cephalograms of 20 patients who had been treated with Forsus FRD were used for this retrospective study. The mean age at the start of treatment was 16.2 +/- 3.8 years. Selected cephalometric variables at the beginning of the FRD phase (T1) and that following completion (T2) as well as the differences between the 2 values were recorded for each variable. The results indicated a palatal tipping of the maxillary incisors and a labial tipping of the mandibular incisors. The SPPS, MPS and IPS width measurements showed a mean increase but this was not found to be statistically significant. The change in SN-CVT showed a significant positive effect on changes in all variables related to the upper-airway dimension. On the other hand, changes in SNA, SNB and SN-MP did not significantly alter the upper-airway dimension. Forsus FRD therapy was not found to contribute to a significant increase in upper airway dimensions
