An interventional study of Corticision and Traditional Non-accelerated Treatment in Crowding of Anterior Mandibular Teeth, sponsored by Damascus University. Completed at 1 site in Syrian Arab Republic. Open to participants aged 18 Years to 24 Years. Per ClinicalTrials.gov, last updated 2020-10-26.

The duration of orthodontic treatment is one of the exacerbation causes of orthodontic pain. Several methods have been suggested to reduce the duration of orthodontic treatment classified to surgical and non-surgical methods.
Researchers used minimally invasive surgical methods like corticision, piezocision, micro-osteoperforation, and piezopuncture indicated that most of these methods can accelerate dental movement by 20 - 40%.
The effect of corticision as a minimally invasive procedure on root resorption and dehiscence formation during orthodontic tooth movement has not been studied yet.
Applying corticision on the lower anterior teeth using a surgical blade and a hammer may accelerate tooth alignment during orthodontic treatment. This study consists of two groups, patients will be randomly assigned to one of these two groups.
Orthodontically induced external root resorption accompanying orthodontic treatment is defined as a microscopic loss of root tissue as a result of the inflammatory reaction that occurs in the area of application of orthodontic force. It can be diagnosed and measured using conventional radiography or cone-beam computed tomography (CBCT).
Dehiscence is a loss of alveolar bone on the facial (rarely lingual) aspect of a tooth that leaves a characteristic v-shaped, root-exposed defect from the cementoenamel junction apically. Bone dehiscence cannot be detected through conventional radiography or clinical examination. Actually, CBCT can be considered the best accessible technique providing 3D data.
Corticision is one of the minimally invasive surgical procedures that is not associated with flap lifting. It was used to accelerate tooth movement in animals and case report studies. Its application on humans may aggravate their fear and anxiety towards the pain that may accompany this technique.
No randomized controlled trial (RCT) has compared flapless corticision in the non-extraction-based orthodontic decrowding of lower anterior teeth (LAT) with the conventional treatment in terms of external apical root resorption (EARR) and dehiscence formation (DF).

Patients in this group will be subjected to corticision to accelerate orthodontic movement
Procedure: Corticision
Patients in this group will undergo normal traditional treatment without any acceleration method.
Other: Traditional Non-accelerated Treatment
A special instrument will be used to cut the cortex of the alveolar bone at different locations between the lower anterior teeth
The normal sequence of treatment steps will be followed in this group without using any kind of acceleration methods
Change in Root Length
Cone-beam computed tomography imaging will be used for the lower jaw. Root length will be measured for each root of the six lower anterior teeth The change will be calculated between 'before' and 'after' images in mm.
Time frame: T1: one day before the beginning of the orthodontic treatment, T2: exactly at 12 months following the onset of orthodontic treatment
Change in Dehiscence Proportion
Cone-beam computed tomography imaging will be used for the lower jaw. Any V-shaped bone defect located buccally or lingually in the lower anterior region involving bone margin is preliminarily identified as dehiscence. This is going to be measured and the proportion of the presence of such defects will be calculated on two different occasions (T1 and T2).
Time frame: T1: one day before the beginning of the orthodontic treatment, T2: exactly at 12 months following the onset of orthodontic treatment
