Correct answer: D — Band and loop space maintainer

A band and loop space maintainer is indicated for unilateral premature loss of a primary molar when the tooth adjacent to the space can serve as an abutment. A band is cemented on the first permanent molar (or adjacent primary tooth) and a stainless-steel wire loop maintains the space for eruption of the successor (second premolar). A distal shoe is used only when the permanent first molar has not yet erupted. A lingual arch is for bilateral space maintenance.
