Evaluation of a 3-D printed partial denture for children

Official title: Clinical Evaluation of 3-D Printed Partial Denture Space Maintainer and Its Impact on Children's Oral Health Status: A Randomized Controlled Clinical Crossover Study

Run by Tanta University · NCT06825273 · Data updated 2026-11-12

This study tests a new 3-D printed partial denture for kids who lost their baby molars early to see if it can help keep space for their adult teeth and support healthy gums.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are healthy children who have recently lost lower primary molars and are expected to have their permanent successors erupt within a specific timeframe.

Probably not a fit

Patients who exhibit poor oral hygiene, have abnormal occlusion conditions, or are uncooperative may not benefit from this study.

What this trial studies

This clinical evaluation focuses on the use of a 3-D printed partial denture space maintainer designed for children who have lost their primary molars prematurely. The study aims to assess the effectiveness of this innovative approach in maintaining space for permanent teeth and promoting gingival health. By utilizing digital technology, the study seeks to enhance the reliability and durability of space maintainers while reducing the time required for manual manufacturing. The target population includes healthy children who meet specific eligibility criteria related to their dental health and cooperation.

Why it matters

Potential benefit: If successful, this approach could provide a more efficient and effective solution for preventing malocclusions in children who have lost primary teeth.

How similar studies have gone: While the use of digital technology in pediatric dentistry is advancing, this specific application of 3-D printed space maintainers is relatively novel and has not been extensively tested in prior studies.
