For a single premature loss of a posterior primary molar, a fixed, simple appliance that preserves the space is ideal. The band-and-loop space maintainer fits this need: a band is cemented onto the adjacent tooth and a short loop extends into the space to hold it open. It provides reliable space maintenance with minimal chair time, no reliance on patient cooperation, and without affecting other teeth or occlusion.

Other options are less appropriate for one lost tooth: a Nance holding arch and a lingual arch are bulkier fixed appliances designed to preserve space when multiple posterior teeth require support and typically involve more than one abutment contact; removable space maintainers depend on patient compliance and can be lost or damaged, making them less dependable in a young child.
