Summary

This study looks at whether digitally made dental appliances work better than traditional ones for keeping space open in children's mouths after baby teeth are removed. About 115 healthy kids aged 8-9 who had upper baby molars taken out will be involved. The goal is to see which type of appliance maintains the arch shape and width more effectively.
