Estimation of Change in Pharyngeal Airway Passage Dimensions with Twin-Block Appliance in Patients with Class II Malocclusion
Journal Title: International Journal of Medical Research Professionals - Year 2018, Vol 4, Issue 5
Abstract
Background: Angle Class II malocclusion with mandibular retrognathia is a common dento-facial deformity. It is characterized by skeletal retrusion of mandible with skeletal or dentoalveolar protrusion of maxillary. Aim of the Study: To estimate changes in pharyngeal airway passage dimensions with twin-block appliance in patients with Class II malocclusion. Materials and Methods: The present study was conducted in the Department of Orthodontics and Dento-facial Orthopedics of the dental institution. For the study, we selected 30 subjects in the age range of 8 to 14 years with skeletal class II malocclusion associated with mandibular retrusion. Subjects with a history of orthodontic treatment, anterior open-bite, severe proclination of the anterior teeth, and any systemic disease affecting bone and general growth were excluded from the study. Results: A total of 30 subjects were included in the study. The age of subjects ranged from 8-14 years. Number of male subjects was 13 and female subjects were 17. We observed that DNP was increased by0.34, HNP increased by 0.43 mm, DOP increased by 2 mm, DHP increased by 1.69 mm, SPL decreased by 1.69mm, SPT increased by 0.38 mm and SPI decreased by 2 mm. The results for DOP and SPT were statistically significant (p<0.05). Conclusion: From the results we conclude that the use of twin-block appliance for class II patients corrects sagittal dimension of oropharynx and hypopharynx.
