About this trial
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.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Class II molar relationships bilaterally, with fully erupted 2nd molar.
No or minor crowding on the mandible to [reserve Class I posterior occlusion after treatment.
Good oral health free from caries and periodontal problems at the start of treatment.
Disqualifiers
Previous history of orthopedic and/or orthodontic treatment.
Patients with cleft lip and palate and/or craniofacial syndrome
Patients with bad oral habit.
Active periodontal disease.

Trial outcomes
Primary outcomes
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.
Secondary outcomes
Patient discomfort
• Patient's pain and discomfort using visual analogue scale (VAS). The minimum score is zero and the maximum score is 10.
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. - 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
