Multilayer Screw-Retained Zirconia CrownBestoDental multilayer screw-retained zirconia crowns uses a natural gradient of colour and translucency not requiring the use of porcelain layering. They deliver a combination of esthetics and strength, ideal for anterior and posterior implant restorations. Advanced digital milling means that the screw channel can be aligned accurately and the fit is stable over a long period of time. They are ideal for full-contour implant crown cases.

|
ASC Screw-Retained Zirconia CrownOur ASC screw-retained zirconia crowns feature a screw channel at an angle to address the more complex implant angulations. This design is beneficial in obtaining better access to screw while preserving the best esthetics, as no visible screw holes are present in critical areas. They are manufactured via high-precision CAD/CAM technology, which guarantees precision and reliability for long-term use. They can be used with non-ideal sized implants or those with limited screws.

|
Full Contour Screw-Retained Zirconia CrownBestoDental full contour screw-retained zirconia crowns are monolithic, providing maximum strength and durability. They have removed the need to layer materials to minimize chipping hazards, but retain high functional performance. Digital precision ensures accurate screw channel alignment and stable implant connection. They are suitable for high-load posterior implant restorations requiring long-term reliability.

Screw-Retained Zirconia Crowns
Screw-Retained Zirconia Crowns
Our Screw-Retained Zirconia Crowns are intended for implant-retained restorations which need to be retrievable, precise and have long-term durability. They offer a dependable alternative for the single-tooth implant restoration of optimum esthetics and function.
- Screw-retained design eliminates the need for cement, reducing the risk of peri-implant complications.
- High-strength zirconia material ensures excellent fracture resistance under functional loading.
- CAD/CAM precision fabrication provides accurate fit and stable occlusal contact.
- Ideal screw access channel positioning allows easy maintenance and retrievability.
Clinical & Technical Information
Screw-retained zirconia crowns are implant-supported restorations developed to meet the criteria of retrievability, excellent biomechanical stability and superior esthetic results without cement. They are utilized in a broad range of situations where passive fit, long term maintenance and esthetic integration are necessary, such as with the single implant case. BestoDental manufactures all screws-retained zirconia crowns using a fully digital CAD/CAM process to guarantee accurate implant interface compatibility, stable occlusion and predictable clinical results.
1. Indications
Our screw-retained zirconia crowns are suitable for:
- Single implant-supported crown restorations requiring retrievability
- Anterior implant cases demanding high esthetic outcomes
- Posterior implant restorations requiring strong functional load resistance
- Cases where cement-free restorations are preferred to avoid residual cement risks
- Implant positions requiring precise angulation correction (ASC systems)
- Patients with peri-implant tissue sensitivity requiring clean restoration margins
- Digital implant workflows based on intraoral scanning or conventional impressions
- Cases requiring easy maintenance and long-term prosthetic retrievability
- Situations requiring screw-access channel optimization for esthetics and function
- Patients needing high-strength, metal-free implant restorations
- Cases with limited interocclusal space requiring compact restorative design
- Implant restorations requiring high precision fit and passive occlusion

3. Aesthetics
Our aesthetics of screw-retained zirconia crowns
1) Screw-access optimized esthetics
Carefully designed screw channels minimize visible access points while maintaining functional retrievability and esthetic integrity.
2) Natural tooth-like appearance
High-quality zirconia materials provide excellent translucency and shade matching for natural integration with adjacent dentition.
3) Metal-free esthetic advantage
Elimination of cement and metal substructures enhances gingival color stability and reduces gray discoloration risk.
4) Customized anterior esthetic control
Layered and high translucency options allow enhanced esthetic outcomes in visible anterior implant regions.
5) Stable long-term color performance
Zirconia maintains excellent resistance to staining, ensuring consistent esthetics over time in oral conditions.
Order FAQs
1. What information is required for a screw-retained zirconia crown case?
Please provide the patient’s full name, implant position, implant system, and platform size. STL/PLY scan data, scan body information, antagonist arch scan, bite registration, and shade selection are required. It is also important to confirm whether a straight or angulated screw channel is needed based on implant angulation.
2. Do you believe that digital impressions are a good idea and what are the systems compatible with?
Yes. We are 100% behind digital impressions and accept STL and PLY files from all major intraoral scanners including 3Shape, exocad, Medit, iTero and Dental Wings. All these files are handled by our CAD/CAM system to assure proper screw channel alignment and proper restoration fit.
3.What is the average time for screw-retained zirconia crowns?
It takes in the range of 3-5 working days from receiving all information and design approvals. If a case involves complex angulations and/or special screw channel design, it could take a little longer.
4. What are the benefits of screw-retained zirconia crowns over cement-retained crowns?
Screw-retained crowns minimize excess cement which decreases peri-implant inflammation. They can be easily retrieved for maintenance or repair purposes without harming the restoration.
5. How is screw channel angulation managed in complex implant cases?
We use digital angulation correction and customized screw channel design (ASC when needed) to optimize screw access position while maintaining esthetics and structural strength of zirconia crowns.
6. Is it possible to use screw-retained zirconia crowns in an esthetic zone?
Yes. The advanced screw channel angulation mechanism allows the screw-retained zirconia crowns to be used even in the anterior region with a natural appearance while minimizing the visibility of access holes.
7. What factors are important for achieving accurate fit and occlusion?
Accurate scan body positioning, high-quality opposing arch scans, and precise bite registration are essential. Information about implant angulation and occlusal scheme also helps ensure proper fit, contact distribution, and long-term stability.
