A space maintainer is a dental device used in children to keep the space open for a permanent tooth when a baby tooth is lost too early. It helps prevent other teeth from shifting into the empty space, which could cause misalignment or crowding issues in the future.
Types of Space Maintainers:
Fixed Space Maintainers (cemented in place)
Band and Loop: Used when a single baby tooth is lost.
Crown and Loop: Similar to band and loop but includes a crown for additional support.
Lingual Holding Arch: Used for missing teeth in the lower jaw, often for multiple missing teeth.
Nance Appliance: Used for upper jaw space maintenance, with an acrylic pad touching the palate.
Removable Space Maintainers (similar to a retainer)
Made of acrylic and sometimes include artificial teeth if multiple teeth are missing.
When Are Space Maintainers Needed?
When a baby tooth is lost too early due to decay, injury, or extraction.
To prevent nearby teeth from shifting into the empty space.
To avoid future orthodontic issues like crowding or improper tooth eruption.
Care for a Space Maintainer:
Maintain good oral hygiene to prevent plaque buildup.
Avoid sticky or hard foods that could dislodge the device.
Visit the dentist regularly for check-ups to ensure proper function.
