At Trident Dental Laboratories, we provide meticulously crafted full-contour zirconia dental implants and crowns using the most cutting-edge technology. Our zirconia crowns and bridges offer the most exceptional flexural strength out of all-ceramic options available in the market today.
Our high-caliber team of technicians uses the art of digital dentistry to make sure every full-contour zirconia crown has an absolutely smooth surface, eliminating any abrasion against natural dentition. Trident Dental Lab’s zirconia dental restorations are 100% biocompatible and do not contain metal.
Why Choose Zirconia Crowns & Bridges
If your patients need a complete restorative solution, but do not want anything made from metal, zirconia is the best option for almost all indications. This material is also an excellent option for patients with known metal sensitivities or allergies.
Compared to PFMs, full-contour zirconia crowns tend to be more aesthetically pleasing since they eliminate the likelihood of any dark lines around the gums. Zirconia crowns and bridges also come in a range of translucencies, offering the material flexibility to work esthetically in all regions of the mouth, while maintaining high flexural strength.
Important Information Regarding Zirconia Dental Crowns
Indications
Full-contour zirconia crowns and bridges are extremely versatile so they can be used in a wide variety of situations – from screw-retained implant crowns, inlays/onlays, single crowns, and all spans of bridges with any combination of abutments.
Contraindications
When your patients’ aesthetic expectations are high and it is crucial that the dental restorations match nearby or adjacent natural dentition. If bonding is required to retain the restoration, bond strength is less predictable and lacking in strength compared to other ceramics.
Preparation
Feather-edge preparation is not recommended with zirconia dental restorations. A shoulder margin or a mild chamfer works perfectly. A 1mm occlusal, lingual, and buccal reduction is the minimum required. If reduction more than 1mm is restricted, other material options may be a better choice, such as a PFM.
To adjust a full-contour zirconia crown and bridge, use water and air spray to keep it cool and to avoid micro-fractures with a fine-grit diamond. If you are only using air, make sure to use the lightest touch while making the adjustments. A tapered bur is best for lingual and buccal surfaces; a football-shaped bur is best for lingual and occlusal surfaces.
To polish the zirconia crown, use a porcelain polishing system.
Cementation
A full-contour zirconia dental crown must be cemented using a zirconia primer, such as Clearfil Ceramic Primer from Kuraray or Z-Prime from Bisco. Another option is to use a resin-reinforced glass ionomer (like RelyX Luting cement).
In case a stronger bond is required due to the lack of a retentive preparation, it is recommended to use resin cement such as RelyX Ultimate or RelyX Unicem. Make sure the interior surface of the full-contour zirconia crown is thoroughly cleaned before you cement it, to achieve maximum bond strength.
