Summary
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.
