Spacers

The best space maintenance therapy is the preservation of the primary molars until they are lost naturally. Sometimes, when the teeth are unrestorable, the need for extraction is unavoidable. The purpose of the space maintainers or “spacers” is to preserve the space for the developing permanent teeth.

Some Common Space Maintainers:

  • Lower Lingual Holding Arch (used in the lower jaw with more than one missing tooth.)

  • Band and Loop (single missing tooth.)

  • Nance Appliance (used in the upper jaw with more than one missing tooth.)
