Comparing PEEK and Monolithic Zirconia Band and Loop Space Maintainers for Children Ages 6 to 11

What this Trial Is About

This research focuses on children aged 6 to 11 who need space maintainers after the removal of their lower first primary molars. It compares two types of tooth-colored band and loop space maintainers made from Polyetheretherketone PEEK and monolithic Zirconia BruxZir. The study aims to assess how well these space maintainers perform clinically, including how often they come loose or break, the health of the gums nearby, and the wear on the opposing teeth over one year. After both lower first primary molars are extracted, dental impressions will be taken using an intraoral scanner. These impressions are sent to a CADCAM lab where two space maintainers will be madeone from PEEK and one from monolithic zirconia. Once fabricated, both appliances will be cemented in place with a special resin cement. Photos will be taken after placement, and participants and their parents will be informed about oral hygiene and asked to report any issues such as discomfort or damage. Participants will be monitored over a one-year period to evaluate the clinical performance of the space maintainers and the health of the gums next to them. The study team will also assess wear on the teeth opposing the space maintainers. Parents will be asked to notify the team if there are any problems with the appliances. Overall, the trial will help understand how these materials perform for childrens dental care needs.
