Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The study sample will consist of 66 patients with 3-6mm crowding. The sample will be allocated randomly into two experimental groups, in addition to a control group.
The brackets will be applied using indirect bonding method for all patients. The dentoalveolar changes occurring after leveling and alignment teeth will be assessed by using CBCT radiographs; pre and post- treatment changes for each group will be evaluated individually.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Fixed appliances will be applied into three groups as 1. Active self ligating brackets (ASLB), 2. Passive self ligating brackets (PSLB), 3. Conventional brackets (CB) until reach to wire 19\*25 S.S upper and lower. During leveling, thermal activated wires will be used in all patients.
CBCT images will be done before and after leveling and alignment of teeth to compare dentoalveolar changes between study groups.
