Zirconia inlays / onlays
Zirconia inlays and onlays made to the cavity prepared by the dentist, rebuilding cusps with a metal-free material.

Zirconia post & core
Zirconia cores made from the canal and prepared-tooth shape supplied by the dentist, supporting all-ceramic restorations.
What is it?
A post and core is placed in a root-treated tooth to support the crown above it. A zirconia post and core contains no metal and is usually chosen when the dentist plans an all-ceramic restoration.
Typical indications
- Root-treated teeth with little remaining crown that need a core to retain the crown.
- Aesthetic zones where metal showing through the ceramic should be avoided.
The dentist assesses the root, the remaining tooth structure and the occlusion before deciding.
CAD/CAM workflow
- Receive the impression or scan of the canal and prepared tooth.
- Design the core in CAD along the root axis and the preparation margin.
- Mill from a zirconia blank, stain and sinter.
- Finish, check fit on the model and deliver to the dentist.
Advantages
- Colour matches all-ceramic crowns and avoids a dark shadow at the neck.
- Individually designed for each root.
- The digital workflow gives good control of shape and shortens back-and-forth.
Notes
Core retention depends on root length and shape, the luting technique and chewing forces. Technicians fabricate to the agreed design; clinical decisions remain with the treating dentist.

Quick comparison
How do zirconia restorations differ?
A summary of the main differences between the six categories. Every case has its own indication; please discuss with your dentist to choose the right solution.
| Restoration | Structure | Aesthetics | Strength and load | Common indications |
|---|---|---|---|---|
| Zirconia implant restorations | A zirconia crown or bridge seated on dental implants. | Metal-free; the aesthetic level depends on a monolithic or layered design. | Depends on bone, occlusion and number of implants; assessed by the dentist. | Replacing one or several missing teeth with implants. |
| Zirconia post & coreViewing | A core placed in a root-treated root canal to support the crown. | Metal-free, which limits dark shadows at the cervical area. | Depends on root length, root shape and chewing load. | Root-treated teeth with little remaining tooth structure. |
| Zirconia inlays / onlays | An indirect restoration sitting inside the cavity (inlay) or covering one or more cusps (onlay). | Metal-free, with a colour that blends with the tooth. | Depends on the quality of cavity preparation and the remaining tooth structure. | Large caries or fractures, replacing old fillings; preserving tooth structure. |
| Porcelain veneers | A thin porcelain shell bonded to the outer surface of the tooth. | Mainly intended to improve the shape, size and shade of the front teeth. | Thin, so it needs proper care and avoiding biting on hard objects. | Front teeth differing in shape or shade, small gaps, slight chipping of the incisal edge. |
| Full-contour zirconia | Monolithic zirconia with no porcelain overlay. | The effect at the front teeth can differ from a layered framework. | With no veneering layer, the risk of chipping is lower. | Posterior teeth under heavy load, limited occlusal space, bruxism. |
| Layered zirconia crowns | Two layers: a zirconia framework inside and a veneering ceramic outside. | Can reproduce colour and translucency close to natural teeth; suited to high-aesthetic zones. | The framework carries the load; the veneering ceramic may chip under unsuitable loading. | Front teeth and areas needing a high aesthetic effect. |
