The use of 3D printing technology to produce dental restorations has recently been introduced in the market and has become popular as a new production method. The development of optimized filler distribution has significantly improved the mechanical properties and long-term stability of the restoration. This study aimed to compare the wear resistance of 3D printed composite resin material for crown and bridge applications. Four samples (n=4) of three different 3D printable composite resin materials were tested. The materials were GC Temp PRINT(GC), Nextdent C&B MFH (3D Systems) and CROWNTEC (Saremco dental). All specimens for the three-body wear test were printed with Asiga MAX UV printer and post-cured with the light curing device and the settings recommended by the respective manufacturer. They were submersed in 37Cwater for 24 hours, subsequently they were subjected to 100,000 cycles at a load of 0.84 MPa in a wear simulator. An acrylic plate was used as antagonist, and a slurry of PMMA and glycerin as abrasive medium was applied to the contact area during test performance. Wear value was calculated as the difference in specimen height before and after the three-body wear. Results were analyzed by one-way ANOVA (p<0.05). Also, the specimens were examined with a FE-SEM. It was found that GC Temp PRINT (16.36.6um) and CROWNTEC (35.530.2um) had significantly lower wear value compared with Nextdent C&B MFH (86.79.0um), though fillers were observed in all materials. Within the limitations of this study, GC Temp PRINT showed higher wear resistance property thanks to its uniformly dispersed fillers and the proper silane treatment of the filler surface. Consequently, it was predicted that GC Temp PRINT can be durable for long term use in the oral environment.
