Comparing 3D-printed vs. traditional dental space maintainers
Part of Mouth & dental clinical trials.
This trial tests two ways of making a small dental device that holds space for adult teeth when baby molars are lost early. It compares a 3D-printed version with a conventionally made one, to see which works better and is more comfortable.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your child is generally healthy and does not have any long-term medical conditions.
- Both lower first baby molars (the first big molars in the lower jaw) have been lost early on both sides.
- X-rays show that the permanent tooth underneath is present and healthy, with at least 1.5 mm of bone above it.
- Your child's bite is normal for their age (flush terminal plane or mesial step in baby teeth, or Angle class 1 in mixed teeth).
- The teeth next to the missing ones are healthy, with no cavities or gum problems seen on exam or x-ray.
- Your child is cooperative and not anxious — they have a Frankl behavior rating of 3 or 4 (positive or definitely positive).

This study tests two types of tooth-colored space maintainers (PEEK and BruxZir) in children who lose both lower first baby molars. The goal is to keep the space open for the permanent teeth to come in properly.
This trial compares two types of dental restorations (3D-printed and milled) to see which one wears better and stays smoother over time. It may help people who have lost part of a tooth's chewing surface.
This trial tests if a 3D-printed space maintainer works as well as the standard metal one to hold space after a baby tooth is lost. It may help kids who need to keep space for a permanent tooth coming in.
This study compares two types of dental devices that hold space in a child's mouth after baby molars fall out early. The research tests whether a newer 3D-printed version works as well as or better than the traditional wire-based device.
This study tests a 3D-printed space maintainer (like a small partial denture) for children who have lost a lower baby molar early. It helps keep space for the permanent tooth to come in properly.
This study compares three different types of devices that keep space open in a child's mouth after an early primary (baby) tooth is lost, so the permanent adult tooth can come in properly. Your child will be randomly assigned to receive one of the three types and will be followed to see which works best.
