The purpose was to analyze the stress distribution of onlays with composite resin foundation restorations and to investigate the potential benefits of preserving the remaining dental tissue.A three-dimensional finite element model of a mesial proximal defect of the mandibular first molar after endodontic treatment was established. Four types of onlay restorations (GA and GB: complete-coverage onlay; GC and GD: partial-coverage onlay) were designed using this model. After the models were established, a fixed vertical load of 600 N and an oblique load of 200 N were applied, and the stress distributions were compared between the monolithic ceramic block restorations (GA and GC) and those with foundation restorations (GB and GD).
