Brief Summary
In orthodontics, the teeth tend to move to the extraction space. This tooth movement becomes of larger importance when there is a crowding. During the COVID lockdown period, It was noted that some cases have a significant improvement and almost all the crowding was relieved without appliance activation.

Study Arms (2)
Braces
ACTIVE COMPARATORFixed appliance would be bonded post teeth extraction (premolars). subsequently, leveling and alignment using sequence of archwires would be followed. The measurements would be done using models each month.
Without braces
NO INTERVENTIONExtraction of premolars and only observing the case over time. The measurements would be done using models each month.

- Fully erupted teeth from 1st molar to the 1st molar.
- Patients with periodontally sound dentition.
- Patients with good general health. No previous history of extraction or orthodontic tooth movement.
You may not qualify if:
- Cases requiring orthognathic surgery.
- History of systemic and medical illness.
