At Edentalab, we offer both screw-retained and cement-retained implant crowns, each designed to address specific clinical needs. Both types provide exceptional stability ,esthetics and long-term durability. Using advanced materials such as zirconia, E.max, or PFM, Whether for single crowns or multi-unit bridges, each restoration is tailored to the individual needs of the patient and implant system
Technical Specifications

- Zirconia (monolithic or layered)
- E.max (Lithium Disilicate)
- Porcelain-Fused-to-Metal (PFM) for certain clinical needs
- Fabrication Methods:
- CAD/CAM Milling (for zirconia, E.max, and PFM)
- Traditional Casting (for PFM and certain metal alloys)
- Implant System Compatibility: Compatible with any implant systems
- Cementation:
- Resin-based adhesive cement
- Resin-modified glass ionomer cement, depending on system and clinical requirements
Screw-Retained vs Cement-Retained Implant Crowns
| Feature | Screw-Retained Implant Crown | Cement-Retained Implant Crown |
| Retention Method | Mechanically cement at the lab | Clinician cement in the mouth |
| Indications | Posterior crowns, multi-unit bridges, functional restorations | Anterior crowns, esthetic restorations, high-visibility zones |
| Esthetics | Screw access hole visible (usually covered) | No visible screw access, more seamless esthetics |
| Retrievability | Easy to remove and replace due to screw access | Difficult to retrieve without damaging the crown or abutment |
| Material Compatibility | Compatible with zirconia, E.max, PFM | Compatible with zirconia, E.max, PFM, and ceramics |
| Procedure Complexity | Moderate; requires precise screw tightening | Requires proper cementation techniques and no excess cement |
| Long-Term Stability | Excellent stability, minimal risk of loosening with proper torque | Reliable stability if cemented correctly, risk of cement washout |
| Ideal For | Functional and long-lasting posterior restorations, bruxers | Highly esthetic anterior restorations, where appearance is crucial |
| Cementation Risk | No cement-related complications | Risk of excess cement causing peri-implantitis if not managed properly |
| Cost | Generally more affordable | Slightly more expensive due to technique and cementation requirements |
