Summary

this study aims to compare the clinical performance of hard hybrid ceramics and composite resin indirect restorations fabricated by CAD/CAM technology for the vital teeth with occluso-proximal cavities. the clinical performance assessed include marginal adaptation primarily and in addition to Color match, marginal discoloration, aesthetic anatomic form, recurrent caries and restoration fracture and post-operative hypersensitivity. the clinical performance will be assessed after the restoration cementation, after 6, 12, 18 and 24 months.

Conditions

  • Dental Caries
  • Cavity, Dental
  • Proximal Dental Caries

Interventions

OTHER

hybrid ceramics

after caries removal, inlay cavity preparation and immediate dentin sealing, the cavities were scanned using intraoral scanner and the restoration designed and milled using Hard Hybrid Ceramic Blocks. the intaglio surface was air-abraded with 50 μm Al2O3 for 10-15 seconds. SHOFU HC Primer will be applied to the hybrid-ceramic group.

OTHER

Composite resin

after caries removal, inlay cavity preparation and immediate dentin sealing, the cavities were scanned using intraoral scanner and the restoration designed and milled using Composite Resin Blocks. the intaglio surface was air-abraded with 50 μm Al2O3 for 10-15 seconds.
