Long- and short-term space maintenance following the uprighting of molars: a case report

The technique of using a light-hardened glass-ionomer-resin cement restorative material and a stainless steel round wire as a long-term retentive space maintainer following the uprighting of mandibular molars is introduced through the report of a clinical case. The technique is modified for incorporation into provisional acrylic resin restorations as a short-term retentive space maintainer in the time interval between the impression and the cementation of the fixed partial denture.
