Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Material and methods: The study will consist of two groups, each group has 10 Patients. The patients will be selected from the outpatient clinic of the orthodontic department at Mansoura University.
Patients will be divided into 2 groups, group 1 will be treated by direct bone anchored pull distal slider, and group 2 by indirect bone anchored dual force distalizer.

Detailed Description

this study will be conducted for Comparative Evaluation Of Two Bone-Anchored Maxillary Molar Distalization Appliances: Direct Versus Indirect Anchorage.
Participant and eligibility criteria:
The study will consist of two groups, each group has 10 Patients. The patients will be selected from the outpatient clinic of the orthodontic department at Mansoura University. pretreatment records will be taken including: intraoral and extraoral photographs, study models, panoramic radiographs, and lateral cephalometric radiographs.
Intervention:
written and informed consents will be taken from the patients.
Group 1:
* Two metal bands will be chosen and fitted on the maxillary first molars.
* Rubber base impression material will be taken with bands in place.
* Two metal bands will be placed in their relative positions in the impression and then poured up with stone.
* Send it to the LAB for appliance fabrication.
* At delivery day, the appliance will be cemented on the maxillary first molars by glass ionomer luting cement and two miniscrews will be placed in their positions.
* The appliance will be activated by closed coil spring, which apply 300g force. Patients will be monitored every 3 weeks.
Group 2:
* Four metal bands ( two for maxillary first premolars and two for maxillary first molars ) will be chosen and fitted on the teeth.
* Rubber base impression material will be taken with bands in place.
* Four metal bands will be placed in their relative positions in the impression and then poured up with stone.
* Send it to the LAB for appliance fabrication.
* At delivery day, the appliance will be cemented on the teeth by glass ionomer luting cement and two miniscrews will be placed in their positions, and activated by compressing the NiTi open coil spring, which apply 300g force. Patients will be monitored every 3 weeks.
