Fiber reinforced composite loop space maintainer: An alternative to the conventional band and loop

The stainless steel band and loop appliance is the most commonly used fixed space maintainer in pediatric dentistry. But there are several disadvantages with this appliance such as the need for a cast or a working model, decalcification of the abutment tooth, loosening because of breakage or dissolution of the luting agent, tendency to get embedded in the soft tissue and the possibility of metal allergy. The purpose of this article is to present a simple, laboratory design of a “Fiber Reinforced Composite” (FRC) loop space maintainer and discuss the advantages over the traditional band and loop space maintainers.
