Zirconia sintering beads for dental laboratories
DLG zirconia sintering beads are designed to support crowns, bridges, frameworks and zirconia restorations during dental sintering cycles.
Placed inside a sintering tray, they create a stable support bed that helps maintain the restorations during temperature ramp-up, holding stages and cooling. They help reduce mechanical stress, distortion and the risk of microcracks on CAD/CAM zirconia restorations.

CAD/CAM zirconia sintering
An essential accessory for dental zirconia sintering
During zirconia sintering, restorations are exposed to high temperatures and significant thermal variations. The support used inside the sintering tray directly influences restoration stability, heat distribution and final result quality.
Zirconia sintering beads support restorations without creating a rigid pressure point. They support crowns, bridges and frameworks throughout the thermal cycle while promoting improved heat distribution around the restorations.
For a dental laboratory equipped with a CAD/CAM workflow, they are an essential technical consumable for securing zirconia sintering cycles and preserving restoration integrity.
Why use zirconia sintering beads?
Pre-sintered zirconia restorations undergo a major transformation during the sintering cycle. An unsuitable support can create stress, excessive contact areas or instability during material shrinkage.
Zirconia sintering beads help keep restorations in a stable position while reducing localised pressure points.
- Stabilisation of crowns and bridges during the thermal cycle.
- Reduced risk of distortion during sintering.
- More homogeneous heat distribution inside the sintering tray.
- Protection of sensitive areas: margins, connectors and intaglio surfaces.
A mobile support bed for CAD/CAM restorations
The beads create a granular support bed that adapts to the geometry of the restorations. This positioning flexibility is particularly useful for CAD/CAM milled restorations, whose shapes may vary depending on the clinical case.
They support structures without imposing an excessively rigid fixed contact point, helping preserve thin areas during sintering.
- Support without excessive mechanical stress.
- Improved thermal circulation around restorations.
- Stable support for zirconia structures.
- Reduced risk of microcracks and chipping.
Professional applications in the dental laboratory
Zirconia sintering beads are suitable for everyday dental laboratory work requiring reliable and consistent sintering of zirconia restorations.
Compatible restorations
- Single zirconia crowns.
- Zirconia bridges.
- Zirconia frameworks.
- CAD/CAM monolithic restorations.
- Implant-related components according to the laboratory protocol.
Use in a sintering furnace
- Use inside a sintering tray suitable for zirconia.
- Compatible with standard zirconia sintering furnaces.
- Suitable for high-temperature thermal cycles.
- Reusable if the beads remain clean and intact.
- Visual inspection recommended after repeated cycles.
1.4 to 2 mm bead size for balanced support
The 1.4 to 2 mm bead size creates a stable sintering bed while limiting the risk of marking sensitive areas of the restorations.
Smaller beads provide more regular contact, while larger beads may be useful for supporting certain bulkier restorations. The choice depends on the restoration type, geometry and the laboratory’s internal protocol.
Professional usage recommendation
For thin restorations, crowns or standard bridges, it is recommended to check that the beads do not become lodged in intaglio surfaces, implant channels or sensitive anatomical details.
The height of the bead bed must be sufficient to stabilise the restorations without burying them excessively. Controlled positioning helps limit stress during the thermal cycle.
- Avoid burying restorations too deeply.
- Check implant areas and intaglio surfaces.
- Position restorations without direct contact between them.
- Follow the recommendations of the furnace and zirconia material manufacturers.
Best practices for optimising zirconia sintering cycles
The success of a sintering cycle does not depend only on the furnace or the zirconia disc used. Tray loading, bead cleanliness, restoration positioning and compliance with the thermal protocol are also decisive.
Before the cycle
- Use a sintering tray compatible with dental zirconia.
- Check that the beads are clean and free from contamination.
- Remove milling dust or residues from the restorations.
- Inspect margins, connectors and thin areas before sintering.
During loading
- Create an even bead bed inside the tray.
- Position the restorations without direct contact between them.
- Do not overload the sintering tray.
- Follow the recommended sintering curve for the zirconia material used.

FAQ – Zirconia sintering beads
Can zirconia sintering beads be reused?
Yes, zirconia sintering beads can be reused over several cycles if they remain clean, intact and free from contamination.
Regular visual inspection is recommended to remove cracked, worn or soiled beads.
Why use beads instead of a fixed support?
The beads create a more flexible support bed than a fixed support. They better follow the shape of the restorations and reduce localised pressure points.
This configuration also improves thermal circulation around the restorations during the sintering cycle.
Are the beads compatible with all sintering furnaces?
Zirconia sintering beads are intended for standard zirconia sintering furnaces, inside a tray suitable for the furnace being used.
It is recommended to follow the instructions provided by the furnace manufacturer, the zirconia material manufacturer and the laboratory protocol.
How many beads should be placed in the tray?
The quantity depends on the tray size, the number of restorations and their geometry. The bead bed must stabilise the restorations without burying them excessively.
Restorations must remain correctly positioned, without direct contact between them.
Can the beads mark intaglio surfaces?
Incorrect positioning or excessive embedding may mark certain sensitive areas. It is advisable to check the position of the restorations before the cycle.
Intaglio surfaces, implant channels, connectors and thin margins should be checked carefully.
