Fracture resistance of prepared premolars restored with bonded new lab composite and all ‐ceramic inlay/onlay restorations: Laboratory study

ConclusionsThe fracture resistance of prepared teeth for inlay and onlay restorations is inferior to the intact teeth when lab composite is used. Conversely, when a ceramic material being used, the prepared teeth for inlay and onlay restorations showed a comparable strength to the intact teeth especially zirconia ceramic. Clinical SignificancePremolar teeth restored with zirconia ceramic inlays and onlays exhibited fracture resistance comparable to intact teeth.
