Orthodontic and Articular Effects of the One-Step No-Prep Protocol
Summary
NIH's ClinicalTrials.gov registered a new observational study (NCT07533240) investigating the One-Step No-Prep protocol for treating localized tooth wear in adults. The study will evaluate orthodontic tooth movements, temporomandibular joint function, and restoration stability using digital scans, 3D imaging, and jaw-tracking. Participants will receive bonded restorations combined with orthodontic mechanics and complete questionnaires on comfort and satisfaction.
What changed
ClinicalTrials.gov has registered a new study (NCT07533240) examining the One-Step No-Prep protocol, a minimally invasive orthodontic approach combining bonded restorations with simple orthodontic mechanics to treat localized tooth wear in adults. The study will use low-dose 3D imaging, digital scans, jaw-tracking, and clinical exams to evaluate changes in tooth position, bite contacts, facial vertical height, and TMJ function.
For dental researchers and orthodontic practitioners, this registration signals growing interest in conservative, no-prep restoration techniques. The study's findings on long-term stability and patient satisfaction could inform future treatment protocols. Clinical investigators interested in participating should review eligibility criteria on ClinicalTrials.gov.

Orthodontic and Articular Effects of the One-Step No-Prep Protocol
N/A NCT07533240 Kind: NA Apr 16, 2026
Abstract
This study investigates how the One-Step No-Prep protocol with orthodontic assistance affects dental and jaw function in adults treated for localized tooth wear. It focuses on the predictability and extent of orthodontic tooth movements, the impact on temporomandibular joint position and function, and the quality and long-term stability of the restored bite.
Participants will receive minimally invasive bonded restorations combined with simple orthodontic mechanics. The study will evaluate changes in tooth position, bite contacts, facial vertical height, and temporomandibular joint function using digital scans, low-dose 3D imaging, jaw-tracking, and clinical examinations. Patient comfort, function, and satisfaction will also be assessed through questionnaires.
The goal is to better understand how this conservative treatment performs over time.
Conditions: Tooth Wear, Orthodontic Extrusion
Interventions: Low-dose Cone-Beam Computed Tomography
