About

Patients who have severe crowding on the upper jaw that requires two first premolars extraction will be enrolled in this trial. The different types of brackets, such as self-ligating brackets and conventional brackets, and the various acceleration methods, such as corticotomy, have different effects on the orthodontic treatment time and the periodontal tissues. So, this study will assess and compare the overall leveling and aligning time and the changes in periodontal indices between patients with severe crowding, treating with self-ligating brackets associated with flapless corticotomy versus conventional brackets alone versus self-ligating brackets alone.

There are three groups:

The first group (control group): the patients in this group will be treated using conventional brackets alone.

The second group (Experimental group): the patients in this group will be treated using self-ligating brackets alone.

The third group (Experimental group): the patients in this group will be treated using self-ligating brackets associated with flapless corticotomy.

Full description

The prolonged duration of the treatment period can cause many problems such as caries and periodontal diseases. The oral environment is considered a suitable environment for many germs and microorganisms to grow. Any increase in the percentage of these germs predisposes to the occurrence of dental and periodontal problems.

Several studies have used various procedures and many types of brackets to accelerate dental movement in order to reduce treatment time.

Orthodontic treatment using different devices usually contributes to change the nature of the oral environment and its contents of microorganisms Many bracket systems have been used, such as the conventional brackets and self-ligating brackets. The use of self-ligating brackets has increased significantly in recent years. The absence of wired or elastic elements may cause less accumulation of plaque.
