However, when young patients are less cooperative and have a severe gag reflex, using traditional impression methods may be challenging. The use of a conventional metal space maintainer (SM) requires manual laboratory procedures and does not provide optimal esthetics. Moreover, gingival submergence of the wire and gingivitis caused by metal structures may occur. This clinical report describes a complete digital workflow for the fabrication of a zirconia SM to overcome these limitations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Clinical Considerations<\/jats:title><jats:p>An 8\u2010year\u2010old boy with a band and loop SM for a missing primary mandibular right second molar presented with plaque accumulation around the band, soft tissue impingement by the loop, and loss of cement. A reverse band and loop SM had been proposed for the restoration of the primary mandibular right first molar. After conservative tooth preparation, a digital impression procedure was performed. A customized band and loop SM was designed using a computer\u2010aided design software and milled out of the zirconia block.
