ART restorations with HVGIC have shown high success in long-term follow-up studies for single surfaces, in the primary and permanent dentitions, with meta-analyses showing weighted mean annual failure percentages of 5% in primary molars over the first three years, and 4.1% over the first five years in permanent posterior teeth.29 However, there are not enough studies on multi-surface restorations in the permanent dentition to recommend it as a long-term strategy yet.
