The molars were randomly allocated into five groups (<i>n</i> = 21) according to the cervical relocating materials used: Group I had no cervical margin relocation; Group II used a highly viscous glass ionomer; Group III used a highly-filled injectable resin composite; Group IV used a resin-modified glass ionomer; and Group V used a bioactive ionic resin. All groups received immediate dentin sealing before nanoceramic resin-based CAD/CAM onlay restorations. After the specimens were subjected to thermo-mechanical loading, they underwent fracture resistance testing and failure mode analysis.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>No statistically significant difference in fracture resistance was observed among the tested groups.
