An interventional study of Smile Arc Marginal Ridge Approach (SAMRA) and MBT Chart Method in Class I Malocclusion, sponsored by Cairo University. Recruiting at 1 site in Egypt. Open to participants aged 11 Years to 30 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-10-22.
Sponsored by Cairo University · Not applicable, Interventional, and Treatment
The goal of this randomized clinical trial is to evaluate the effect of Smile Arc Marginal Ridge Approach (SAMRA) versus MBT chart method for bracket positioning on orthodontic treatment results.
The main questions it aims to answer are:
Is there a difference in orthodontic treatment results between smile arc marginal ridge approach (SAMRA) and MBT chart method for bracket positioning?
Does SAMRA provide more accurate orthodontic results and reduce the number of archwire bendings and brackets repositioning needed during finishing?
The investigators will compare Smile Arc Marginal Ridge Approach (SAMRA) with MBT Chart Method (gold standard) to see if SAMRA provides more accurate orthodontic results and reduce the need for archwire bendings and brackets repositioning during finishing.
Participants will:

Smile Arc Marginal Ridge Approach (SAMRA) is a new orthodontic bonding technique proposed by Dr. Dalia El Bokle where she stated that it provides more accurate orthodontic results and less time and effort needed during finished. No randomized clinical trials are done on this new approach yet so our study is the first one to test it. 0.018-inch MBT brackets will be used in our study.
For our comparator group MBT Chart Method will be used. Using charts during orthodontic bonding procedures is considered the gold standard. 0.018-inch brackets will be used.
Orthodontic treatment results
Orthodontic treatment results will be assessed according to the American Board of Orthodontics Objective Grading System (ABO-OGS) using the ABO measuring gauge.

Started Aug 2024 (actual). Primary completion is estimated for Aug 2025, 12 months after the start.
Of 23 interventional studies with no phase under Malocclusion, Angle Class I, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 24. This study's planned 12 months is below that.
