Optimal fit of chairside-fabricated distal shoe space maintainer

Background Premature loss of a primary second molar may lead to space loss in the dental arch. This space loss tends to be more severe in unfavourable malocclusions. The distal shoe space maintainer (DSSM) may be beneficial in controlling the path of eruption of an unerupted permanent first molar from the primary into the early mixed dentition. Technique This article describes the technique for achieving optimal fit of a chairside-fabricated band and DSSM in a single visit by contouring the distal shoe blade, and by extending it to the mesial surface of the permanent first molar. Follow-up care Upon the eruption of the permanent first molar DSSM may be modified to a reverse band-and-loop, or replaced by a lingual holding arch.
