Abstract Background: As it is seen, ceramic restorations are adopted by patients and dentists, however, the problem of chipping or fracture are made which made it crucial to repair it intra-orally. Aim of study: The aim of this study was to test the repa-rability of CAD/CAM feldspar ceramic (FP) in contrast to zirconia-reinforced lithium silicate ceramics with composites (Z-LSC). Material and Methods: This study was a case-control study which was conducted in King Abdul-Aziz University Faculty of Dentistry prosthodontics laboratory. Analysis of Variance (ANOVA) was made as statistical analysis. Results: The results are encouraging the use of Feldspar ceramic and it was concluded that Repair bond strength to feldspar ceramic could be improved when surfaces are etched with hydrofluoric acid. Zirconia-reinforced lithium silicate ceramics in not reparable using the tested conditioning proto-cols with composites (Z-LSC). Conclusion: This study is to test the effect of surface conditioning on the reparability of CAD/CAM feldspar ceramic (FP) and zirconia-reinforced lithium silicate ceramics.
