This regulatory update reports on a Mansoura University study assessing how clear aligners compare to fixed appliances in guiding orthodontic tooth movement using diagnostic tests. The trial is listed as active and not recruiting, indicating ongoing regulatory and clinical evaluation of device performance in real world settings. Clinicians, device manufacturers, and regulatory teams may watch for outcomes that inform device safety and effectiveness in practice.
What is being evaluated in this regulatory study?
The trial compares the biomechanical response of orthodontic tooth movement under two modalities which are clear aligners and fixed appliances. It uses a diagnostic data driven approach to characterize potential differences in how each system guides tooth movement. The study is linked to the ClinicalTrials.gov record NCT07399483 and is sponsored by Mansoura University. The documented interventions include diagnostic testing comprising collection of gingival crevicular fluid from the gingival sulcus using paper points, assessment of tooth mobility with Periotest, and 3D digital model superimposition through intraoral scanning.
How are measurements collected and analyzed?
Gingival Crevicular Fluid sampling
Gingival crevicular fluid collection is described as sampling from the gingival sulcus using paper points. The procedure provides a diagnostic data point that can be correlated with orthodontic movement in the context of this trial. No conclusions are drawn about outcomes at this stage; the emphasis is on standardized data collection within a regulatory study plan.
Tooth Mobility via Periotest
Tooth mobility is being assessed with the Periotest device. This objective measurement offers a quantitative readout of tooth stability or movement tendencies during treatment with different appliance types, supporting a comparative biomechanical analysis within the study design.
3D Digital Model Superimposition
3D digital model superimposition using intraoral scanning provides a high fidelity geometric basis for comparing tooth positions over time. The data are intended to complement clinical observations with objective, trackable measurements suitable for regulatory review of device performance in practice.
What are the regulatory implications of these measurements?
The study collects objective biomechanical data to inform an assessment of how two orthodontic modalities influence tooth movement. Findings from this protocol guided trial data may influence regulatory considerations around device performance and safety in use cases that involve clear aligners and fixed appliances. The record notes the sponsor and status, and the ClinicalTrials.gov listing underlines the formal nature of the evaluation and its alignment with standard regulatory expectations for device performance data.
Who is involved in this evaluation?
The sponsor is Mansoura University, and the trial status is active but not recruiting. The ClinicalTrials.gov entry provides the registry details and term information, including a link to the study page for reference. The information presented here reflects the publicly available record, not interim findings.
Data handling and safety considerations
Data collection involves biological samples and digital imaging subject to trial governance. The outlined testing steps are diagnostic in nature and designed to support a regulatory assessment of device related performance. Standard ethical and data handling practices apply as part of trial oversight.
