Comparison of Self-ligating and Conventional MBT Brackets Regarding Alignment Efficiency and Pain Perception

To compare the alignment efficiency and pain experience of Mico-one self-ligating and conventional ligating MBT pre-adjusted brackets in the initial alignment stage of patients undergoing orthodontic treatment.CONVENTIONAL MBT BRACKETS: In conventional brackets elastic ligatures or metal ties are used to ligate the wire in the bracket slot. 2. SELF-LIGATING BRACKETS: Self-ligating brackets like conventional braces are placed relatively the same way.

The exception is that self-ligating braces don't use elastics, or metal ties. Instead it has special clips or brackets with a spring-loaded door. The brackets while maintaing pressure on the archwire, help move the teeth along it at a steady pace .[9] 3 .ALIGNMENT EFFICIENCY Movement of the teeth measured at four months interval. Scoring method involves measuring the linear distance between anatomical contact points between maxillary and mandibular incisors from adjacent tooth anatomical points. (Little's irregularity index)

4.PAIN Unpleasant sensory and emotional experience associated with tooth movement will be measured as a mean using the VAS at 4 hours, 24 hours, day 3, day 7, 1 st Month, 2 nd Month, 3 rd Month and 4 th Month.
