Detaillierte Beschreibung
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) (Coşkun, Aslan and Özkan, 2020; Hassan et al., 2024), 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) (Fathy et al., 2022; Tennert et al., 2024). 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.

- Cavitary preparation involving loss of at least one proximal walls (mesial and/or distal), with intact buccal and lingual walls, and all cavosurface margins located in enamel.
- Presence of functional opposing teeth in stable occlusion
Exclusion Criteria:
- Presence of systemic diseases (e.g., uncontrolled diabetes, immune disorders).
- Current pregnancy or lactation.
- Documented allergy to resin-based composites or adhesive systems.
- Evidence of pulpal necrosis or previous endodontic treatment in the target tooth.
- Presence of cracks or fractures involving the tooth structure.
- Active localized or generalized periodontal disease.
- Evidence of parafunctional habits, including bruxism or clenching.

Experimental: 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.

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.
