Smile Arc Assessment in Orthodontic Patients Following Smile Arc Protection VS MBT Placement Guide Bonding Strategies

Study Overview
=================
Brief Summary
-----------------
The study will be performed on human subjects undergoing orthodontic treatment to correct mild crowding with both techniques enhancing the final smile characteristics of the patients.

Detailed Description
-----------------
The study concisits of two groups, the intervention group entails performing bonding of orthodontic brackets following smile arc protection bonding strategy while the control group entails performing bonding using the MBT placement guide and comparing the final smile outcomes after reaching steel archwires for both groups using customized questionnaires for orthodontists and laypersons.
