Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are systemically healthy children needing bilateral lower deciduous first molar extractions and space maintainers.
✕Probably not a fit
Patients with systemic diseases or those rated with a Frankl score of 1 or 2 may not benefit from this study.

What this trial studies
This clinical trial aims to evaluate the effectiveness of band and loop space maintainers produced using three-dimensional printing technology compared to those made using conventional techniques. The study will involve systemically healthy children who require the extraction of bilateral lower deciduous first molars and the application of space maintainers. A split-mouth design will be used, where one side will receive a 3D printed maintainer and the other a conventional one, allowing for direct comparison of clinical success and effects on periodontal tissues over an 18-month follow-up period. Key metrics for evaluation will include appliance survival, failure criteria, and periodontal health indicators.
Why it matters
Potential benefit: If successful, this study could lead to improved dental treatment options for children, enhancing the effectiveness and comfort of space maintainers.
How similar studies have gone: While the use of 3D printing in dentistry is gaining traction, this specific comparison of 3D printed versus conventional space maintainers is relatively novel.
