Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Trial design
Patients will be randomly allocated into two groups as follow:
1. First group: Buccal segmental digitally printed maxillary distalizer (infrazygomatic mini-implant IZC).
2. Second group: palatal segmental digitally printed maxillary distalizer.
The buccal segmental distalizer will take the anchorage from infrazygomatic miniscrews.
The distalizer will be composed of digitally printed metal shell which is bonded to the palatal surface of the whole posterior segment.
Transpalatal arm will connect the two sides to avoid buccal tipping during distalization.
The distalization will be done by placing chain elastics from the miniscrews to the hook present in the mesial aspect of the appliance.
The palatal segmental distalizer will take anchorage from miniscrews placed in the anterior palate.
The appliance will be bonded to the palatal surface of the posterior segment and containing two anterior and two posterior hooks.
The distalization will be performed by using chain elastics between the anterior and posterior hooks.
Force: 300-350 gram per side which will be measured using force gauge.
A follow-up session will be scheduled every 3weeks, and the appliance will be removed in both groups after the patient reach a Class I relationship. For each patient, two lateral cephalograms will be obtained: one preoperatively and another after completion of distalization.
