An interventional study of Group 1 conventional and Group 2 3D printed in Tooth Movement Techniques and Distalization by Miniscrews, sponsored by University of Baghdad. Recruiting at 1 site in Iraq. Open to participants aged 16 Years to 30 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-09-24.
Sponsored by University of Baghdad · Not applicable, Interventional, and Treatment
A randomized clinical trial to evaluate a newly designed 3D printed miniscrew-supported molar distalization device in comparison to the conventional miniscrew-supported distal jet appliance in correction of Class II malocclusion and upper arch crowding.
It is a multicenter randomized clinical trial with two parallel arms. The patients will be randomly divided into two groups, group one: conventional miniscrew-supported distal jet appliance will be used while for group two, new 3D printed miniscrew-supported molar distalizers is going to be utilized. Lateral cephalometric x-ray and digital models of upper arch will be taken before starting the treatment (T0) and at the end of molar distalization (T1). The effectiveness of the two appliances will be assessed and measured comparing patient's records before and after treatment.
University of Baghdad is the lead sponsor of 164 studies on the registry; 66 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Good oral health free from caries and periodontal problems at the start of treatment.

The rate of molar Distalization
• The efficiency of molar distalization in terms of the amount of molar distalization, degree of distal tipping and bodily translation movements by using a lateral cephalogram linear and angular measurements.
Time frame: 6 months
Patient discomfort
• Patient's pain and discomfort using visual analogue scale (VAS). The minimum score is zero and the maximum score is 10.
Time frame: 10 days
