Overview

  • Hard tissue changes during the transversal expansion of the maxilla using a CAD/CAM expansion appliance.
    • Soft tissue changes during the transversal expansion of the maxilla using a CAD/CAM expansion appliance.

Participants will undergo orthodontic treatment, including:

  • Initial records (intraoral scan, CBCT (cone-beam computed tomography) scan, face scan)
  • Placement of guided orthodontic TADs (Temporary Anchorage Devices)
  • Skeletal expansion using CAD/CAM appliance
  • Fixed multibracket appliance in the upper and lower jaw
  • Intermediate and terminal documents (intraoral scan, CBCT scan, face scan)

Description

This clinical trial aims to evaluate the influence of maxillary expansion using a CAD/CAM-manufactured appliance impact on the soft and hard tissues in the midfacial region in adolescent and adult orthodontic patients.

This study aims to evaluate how this treatment changes the bony structures and soft tissues (for example, the nose) in the mid-facial region during the transversal expansion of the maxilla using a CAD/CAM expansion appliance.

The appliance consists of two anchorage elements on the first molars and two TADs. The mini-screws are placed on the palate under local anesthesia with the help of drilling templates.

CAD/CAD milled and 3D printed guides will be used for the placement of the TADs.

The study will be conducted on orthodontic patients between 12 and 26 years who will receive fixed orthodontic braces in the upper and lower jaw and show a width deficit of the upper jaw.

Intraoral, face, and computed tomography (CT) scans will be used for the investigation. An intraoral and face scanner enables a high-resolution 3D image of the teeth and face. A CBCT Scan is a three-dimensional X-ray image.

These examinations do not involve pain and are performed during regular follow-up appointments.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
