| 520 | _aObjectives: The aim of this study was to investigate the effect of intrusive forces generated during the treatment of deep over-bite in class II division 2 cases on root resorption, by using two different mechanics, mini-screw implants and intrusive archwire. Cone beam computed tomography (CBCT), was used in this study to determine the degree of root resorption. Materials and methods: The study design is a single center randomized clinical trial, parallel design where participants were randomly assigned to either interventional or comparison group with a 1:1 allocation ratio. No changes to the methods after trial commencement occurred. Patients were recruited from the outpatient clinic at the department of. Orthodontics, Faculty of dentistry, Cairo university from March 2015 to March 2017. This study was approved by the research ethics committee, Faculty of dentistry, Cairo university approved this study. All patients were informed about the study procedures. Results: The intrusive arch was able to efficiently intrude the anterior segment(1.14mm) in a period of 6 months. Unfortunately due to the nature of the class II division 2, some laterals werebypassed, to avoid their effects on the leveling and alignment. It was evident that the mini-screws were able to intrude the anterior teeth efficiently(1.29mm) in a period of 6 months. Either before or after treatment; Mini-screw group showed statistically significantly higher mean root length than Archwire group. As regards root resorption, there was no statistically significant difference between mean root resorption values in the two groups | ||
