Space Maintenance, Tooth Loss / Rehabilitation
3D-Printed Versus Band-and-Loop Versus Denovo Space Maintainers in Primary Dentition.
Purpose of the Study When a child loses a "baby" molar early due to a cavity or injury, the surrounding teeth can shift into the empty space. This often blocks the permanent adult tooth from growing in correctly.
- Trial name
- NCT07613658
- Testing
- 3D-Printed Custom Space Maintainer, Conventional Band-and-Loop Space Maintainer, Denovo Chairside Space Maintainer
