Comparing anchorage control methods in orthodontic treatment for canine retraction

Evaluation Of Anchorage Control During Canine Retraction Using Arch Wire Stopper in Comparison to Mini-Screws in Post-Pubertal Patients: A Randomized Clinical Trial

Not applicable Interventional Cairo University · NCT06416904

This study is testing two different ways to hold teeth in place during treatment to see which one works better for pulling back canine teeth in young adults with a certain type of dental alignment.

What this trial studies

This study evaluates the effectiveness of two different anchorage control methods during canine retraction in post-pubertal patients with maxillary dentoalveolar protrusion. Participants will be divided into two groups: one using an arch wire stopper and the other using mini-screws for anchorage. After initial treatment planning and bonding of orthodontic brackets, maxillary first premolars will be extracted, followed by the retraction process. The outcomes will be assessed through digital models and lateral cephalometric radiographs to determine the effectiveness of each method.

Who should consider this trial

Good fit: Ideal candidates are post-pubertal female patients with bimaxillary protrusion or Class II Division 1 malocclusion requiring maxillary first premolar extraction.

Not a fit: Patients with medical complications, active periodontal disease, or previous orthodontic treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve orthodontic treatment outcomes by identifying the more effective anchorage control method for canine retraction.

How similar studies have performed: While there is limited data on this specific comparison, similar studies have explored anchorage methods in orthodontics, indicating potential for success.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Post-pubertal female patients.
* Cases with bimaxillary protrusion or Class II Division 1 malocclusion that require maxillary first premolars extraction.
* Full permanent dentition (not necessitating third molars).
* Good oral hygiene.

Exclusion Criteria:

* Medically compromised patients.
* Active periodontal disease or obvious bone loss in the maxillary arch.
* Patients with habits that are detrimental to dental occlusion (thumb sucking, tongue thrusting).
* Smoking or any systemic diseases.
* Chronic use of any medications including antibiotics, phenytoin, cyclosporine, anti-inflammatory drugs, systemic corticosteroids, and calcium channel blockers. All the above factors affect the rate of tooth movement
* Previous orthodontic treatment.
* Missing teeth.
