• Conditions: Dental Implant

• Registration Number: NCT07066930
• Lead Sponsor: Hawler Medical University

Brief Summary

The goal of this clinical trial is to compare two surgical techniques-Magneto-Dynamic Ridge Splitting and Versah Osseodensification-for expanding narrow alveolar ridges in adults requiring dental implant placement. The main questions it aims to answer are:

Which technique better preserves alveolar bone width after surgery?

Which method results in higher primary implant stability?

Researchers will compare ridge splitting using the Magnetic Mallet to ridge expansion using Versah drills to see if one technique leads to better clinical outcomes, such as improved bone preservation, greater implant stability, and favorable soft tissue response.

Participants will:

Undergo ridge expansion surgery using either the Magnetic Mallet or Versah drills, followed by immediate dental implant placement.

Receive CBCT scans before and 4 months after surgery to measure bone changes.

Undergo implant stability testing using the ISQ (Implant Stability Quotient) method.

Have intraoral scans to evaluate changes in soft tissue volume and thickness.

Detailed Description

This clinical trial aims to evaluate and compare two innovative techniques used to widen narrow jawbone areas (alveolar ridges) in preparation for dental implants. In many patients, the bone in the jaw may be too thin to support dental implants without additional procedures. Traditionally, this problem has been addressed using more invasive surgical methods that can involve bone grafting and extended healing times.

The two techniques being studied are:

Magneto-Dynamic Ridge Splitting (Magnetic Mallet) - This method uses gentle electromagnetic impulses to gradually split and expand the bone. The technique is minimally traumatic, preserves the outer bone layer (cortical bone), and may promote better healing and stability for implants.

Osseodensification (Versah Drills) - This technique uses specially designed rotating drills (Densah burs) that do not remove bone but instead compact it outward, increasing its density. This approach is designed to strengthen the implant site and improve how well the implant integrates with the bone.

The study is a randomized controlled clinical trial conducted at Hawler Medical University. Participants will be randomly assigned to one of the two groups. Both groups will receive immediate implant placement following the ridge expansion procedure, using the same implant system (ROOTT Implants).

Key outcomes to be measured include:

Changes in bone width (buccolingual ridge dimension) using Cone Beam Computed Tomography (CBCT) before and 4 months after surgery.

Implant Stability Quotient (ISQ) values recorded at the time of implant placement and again during the second-stage surgery using a non-invasive resonance frequency analysis device (Osstell).

Soft tissue changes, such as thickness and volume around the implant site, using intraoral scanning technology.

The trial will also monitor patient comfort, healing, and potential complications in each group. By directly comparing these two methods, the researchers hope to determine which approach provides better clinical outcomes in terms of bone preservation, implant stability, and soft tissue health. The results may help establish a new standard in minimally invasive implant site preparation techniques and guide oral surgeons and implantologists in choosing the most effective ridge expansion strategy for their patients.

This study will be conducted in accordance with ethical standards, and all participants will be asked to provide informed consent prior to joining the trial.
