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).

Other trials that look related to this one.
This study compares two types of dental devices that keep space open in a child's mouth after losing a baby tooth, so the permanent tooth can come in properly. One device is 3D-printed and the other is a standard metal one.
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 uses a 3D digital scanner to see what happens to the space in a child's mouth after a lower first baby molar is removed, when no space maintainer is used. It may help dentists better understand natural tooth movement in young children.
This study compares two types of space maintainers (devices that hold space for permanent teeth) in children who lost a lower second molar early. It aims to find which device works better to prevent teeth from shifting and causing bite problems.
This study looks at how chewing patterns change in children who get a space maintainer (a small dental device that keeps a gap open for a permanent tooth to come in). If your child fits the criteria, this trial could help dentists understand the benefits of this treatment for children your child's age.
