ABSTRACT
Objective: To Compare Between Two Different Molar Intruding Systems: 1.The Rapid Molar Intruder Device(RMI) AMERICAN ORTHODONTICS. 2. The Temporary Anchorage Devices (TADs) Orthodontic Screw-OA MCT.

Materials and Methods: This Study Was Conducted On 14 Subjects (5 Males And 9 Females) With Mean Age 15.14�2.81 Years Who Had Anterior Skeletal Open Bite .The Subjects Were Allocated Randomly In Two Equal Groups. Group I (RMI) And Group II (TADs). CBCT Scans Were Taken Before And After The 4 Months Of The Intervention And The Measurements Were Taken By Using Surgical Planning Software (Mimics, Materialize, Belgium Version 10.01).

Results: The Mean Maxillary Molar Intrusion Was 1.4mm And1.2mm When Using (RMI) And (TADs) Respectively . Conclusion: Both Molar Intrusion Modalities (RMI, TADs) Are Effective In Molar Intrusion.
