Evaluation of Sagittal Change in the Maxilla and Incisor Inclination Following Rapid Palatal Expansion Using Cone Beam Computerized Tomography

Objective: To measure the sagittal changes in maxilla via angular change point A with Sella Nasion plane and incisor to palatal before (T1) after (T2) rapid expansion bonded expander.
 Study Design: Quasi-experimental study.
 Place Duration of Study: Armed Forces Institute Dentistry Rawalpindi Pakistan, from Feb 2017 Jan 2018.
 Methodology: 30 patients both male female presenting orthodontics department AFID between ages 9 12 years, transverse maxillary deficiency were given a hyrax appliance an activation schedule 2 turns per day, retention period was months followed by further removable plate. Two cone beam computerized tomography evaluations done. One pre-expansion other (T2).
 Results: children 16 males (53%) 14 females (47%) mean age 11.03 ± 0.76 years studied showing that pre-treatment post-treatment value changed insignificantly 77.03 2.81 77.2 3.02and 1 111.82 5.74 110.8 5.80. Paired sample t-test results confirmed statistically insignificant 1to Palatal Plane.
 Conclusion: Following expander growing location dimension inclination following affected hence clinically.
