Effect of twin block and forsus on Pharyngeal airway dimensions: A comparative study

The objective of this study was to evaluate and compare the effects Twin Block Forsus on Posterior Airway Passage (PAP) pharyngeal wall Thickness (PPWT) in treatment Class II division 1 malocclusion. This a 2-arm parallel, randomized controlled trial. A total 24 malocclusion patients indicated for with functional appliances were equally divided among (3M Unitek Corp, Monrovia, Calif) groups. Skeletal changes, PAP changes PPWT compared using Forsus. randomization determined by computer-generated random number table. Blinding performed both participants data analyser. analysed statistical analysis carried out Student’s t-test T test Equality Means (P <0.05). Significant increase oropharyngeal hypopharyngeal dimensions no dimensional nasopharynx, soft palate thickness length, decompensatory action posterior seen appliances. On intergroup comparison insignificant results observed between indicating similar effect PPWT. Both are effective improving while correcting
