简要总结
This study is a Randomized Controlled Parallel group trial to compare and evaluate the Rate of Maxillary incisors intrusion between Mini Screw and Burstone intrusion arch with helix in deep bite patients conducted in Department of Orthodontics, Government Dental College and Hospital Cuddalore.The primary outcome of the study is to assess and compare the rate of Maxillary incisors intrusion and also to assess and compare the Anchorage loss between Mini Screw and Burstone intrusion arch with helix.The Secondary outcome of the study is to assess and compare the Dentoskeletal and Soft tissue changes and also to assess and compare the Root resorption between Mini Screw and Burstone intrusion arch with helix.Total Time period of the study is 17 months.Total sample size was calculated to be 98 including the expected dropout rate of 20%.
