Tooth Crowding
Conditions
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.
Detailed description
In this randomized controlled trial, a sufficient number of patients would be randomly assigned into two groups; one with braces and one without fixed braces.

Masking description
The two groups will have lingual arches. However, patients without braces will not be informed about their braces before 5 months of trial initiation.
Intervention model description
Two groups; one with fixed braces and one without fixed braces.

Inclusion criteria
\- Patients with permanent dentition between age group of 13 - 30 years. * Maxillary or mandibular crowding \>4.1mm and requiring extraction of maxillary first premolars or mandibular first premolars. The crowding will be measured using a caliper one cast models. * 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.
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Anterior teeth alignment every 4 weeks at each time point. | 6 months | The cumulative before extraction and space closure for 4 months (mean difference before and after).. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Gingival invagination | 9 months | this will be measured by visual inspection intraorally. |
| Molar anchorage loss at each time point. | 6 months | The anchorage loss of molars will be measured over time using the models. |
