2026년 6월 13일 업데이트: Sayed Ahmed Sayed Karim, Cairo University
Clinical Performance of CAD/CAM Hard Hybrid Ceramic Inlays Versus Resin Composite Inlays in Vital Molars With Extensive Occluso-Proximal Cavities: Two-Year Randomized Clinical Trial
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.
연구 개요
상세 설명
A wide variety of materials is now available for the fabrication of indirect restorations used to manage extensive carious lesions, including high-strength ceramics, hybrid ceramics, and resin-composite blocks. Each material offers distinct advantages in strength, wear resistance, aesthetics, and bonding performance, thereby expanding treatment options for severely compromised posterior teeth. However, these differences in mechanical and optical behavior, marginal adaptation, and long-term durability under functional stresses complicate clinical material selection.
Limited data is available comparing the clinical performance of these materials, particularly in large cavities in these regions. More information is needed on how they prevent post-treatment sensitivity, maintain edge quality, and resist discoloration, wear, and fractures.
Though short-term studies indicate excellent survival rates and aesthetic results for CAD/CAM hybrid ceramic inlays (more than 90% survival after two years), and systematic reviews imply that CAD/CAM resin composite inlays match ceramic restorations (success rates ranging from 85.7% to 100% for composites versus 93.3% to 100% for ceramics). There is a lack of direct clinical comparisons between these two material types in vital molars with occluso-proximal cavities. Much of the existing research is constrained to onlay designs or mixed-material groups, creating a significant gap in understanding which CAD/CAM block type delivers superior long-term performance for inlay restorations in vital teeth.

실험적: Hybrid ceramic group
indirect restoration (inlay design) using CAD/CAM Fabricated Hard Hybrid Ceramic blocks
|
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.
