A default cement gap of 0.06 mm and a horizontal margin width of 0.2 mm are recommended.
Adjust the cement gap and margin thickness in the design according to the condition of your milling machine. Because the crystal size of Amber Mill before crystallization firing is nano-scale, its edge-milling performance is excellent, so you may design with a margin thickness of 0.15 mm for the first milling test.

Use a water-cooled air turbine to prevent cracks caused by thermal shock.
If you use a laboratory micromotor without water cooling, wrap the intaglio surface of the restoration with wet tissue while cutting. Cutting quickly at high speed can cause cracks from thermal shock.
Proceed with cutting carefully.

The number of restorations that can be milled depends on the size and type of restoration.
In general, 20–30 restorations can be milled.

Yes, it does.
Mount it in the jig according to the Amber Mill Disk manual.

Diamond-coated (electroplated) burs sold by the milling machine manufacturer are recommended.
The recommended bur geometry may differ depending on the milling template.

They may differ depending on the milling template provided by the machine vendor. In general, milling is commonly done at a spindle speed of 60,000 RPM.
Some vendors provide templates with a slower feed rate to prevent chipping during milling, while others set a faster feed rate to shorten the milling time.

Because tool wear is severe during roughing, splitting roughing into two stages is advantageous for tool life. If machining is largely completed in the semi-finishing stage, it is desirable to minimize finishing.

Each machine manufacturer qualifies the material on its equipment through compatibility testing, so please follow the manufacturer's guidance for exact parameters.

Use the coolant recommended by the milling machine manufacturer.

It depends on operator skill, the condition of the milling machine and the type of restoration (crown, inlay, onlay, veneer, etc.).
In general, about 24–28 blocks per tool.

For a 6–8 L tank, replace the water with the type recommended by the milling machine manufacturer after milling about 40 crowns.
For a tank of about 2 L, replace it after milling about 15 crowns. This also extends the life of the milling burs.

The default cement gap is 0.06 mm (60 µm) and the horizontal margin width is 0.2 mm.
Amber Mill blocks have excellent edge-milling stability, so the margin can be designed at 0.15 mm and milled without chipping at the margin.

To prevent cracks caused by thermal shock, use a water-cooled air turbine and diamond-coated (electroplated) burs.

In general, a sprue diameter of 2.5–3 mm is recommended.

Castable resin generally expands in volume during burnout, which can crack the invested ring; such cracks can break the ring during pressing or create unwanted fin-shaped flash on the pressed restoration. For this reason, rapid burnout is recommended.

26 ml of liquid per 100 g of powder.
Start with a special liquid : distilled water ratio of 16:8, check the internal fit of the pressed result, and then adjust the ratio of special liquid to water.
We recommend keeping the total liquid volume at 26 ml whenever possible.

If the amount of liquid is increased above the recommended total (26 ml), expansion decreases.
At the same total of 26 ml, if the proportion of special liquid is higher than that of distilled water (i.e., more special liquid is used), expansion increases.

It depends on the condition of the furnace, but in general, for one or two 100 g rings, follow the guide of holding at 850 °C for 30 minutes.

Because of the CTE difference between metal firing pins and lithium disilicate, cracks can occur in the restoration. For this reason, metal firing pins are not recommended.

If the drying time in the glaze firing schedule (6 minutes recommended) is too short, the firing table of the porcelain furnace closes and the temperature rises before the glaze is completely dry, causing blackening.
Please follow the recommended firing schedule.

For the crystal phase to change, temperature matters, but a sufficient holding time is also required. This is why the crystallization firing schedule holds the maximum temperature for 15 minutes.
A typical porcelain powder firing schedule holds the maximum temperature for only 1 minute.
Because the holding time at the maximum porcelain firing temperature is as short as about 1 minute, the translucency does not change.

If the drying time during glazing is too short, the glaze liquid is not completely dried through, and the fired result can turn greyish. This is called blackening. In general, observe the 6-minute drying time, and when glazing 10 or more restorations at once, extend the drying time by 2 minutes or more to prevent blackening.

Ingot products are crystallized during the pressing process, but milling blocks and disks must undergo crystallization firing after milling to obtain the desired translucency, shade and strength. During crystallization firing, the lithium crystal phase grows and its density increases, developing strength, shade and translucency.

In laboratory environments where air-conditioner airflow is directed at the porcelain furnace, or where the furnace is by a window exposed to cold drafts, a cooling time is recommended in the firing schedule to prevent cracks in the restoration caused by thermal shock.

Surface bubbles can occur with porcelain furnaces that have a high vacuum level. If your porcelain furnace has a high vacuum level, do not maintain vacuum in the firing schedule—fire in air and surface bubbles will not occur. If a second glaze firing is needed, firing in air will also prevent bubbles.

Use ceramic-specific rubber wheels and points for polishing.
For thicker areas such as occlusal adjustment or surface texture, diamond stone points and wheels reduce frictional heat during polishing and make the work easier and faster.

When burning out restorations printed in castable resin, burning them out quickly prevents fins caused by the volumetric expansion of the castable resin during combustion.
A common method: 1) Place the set investment ring in a burnout furnace that has already reached the maximum temperature of the burnout schedule and hold for 5 minutes so the temperature rises all the way inside the ring. 2) Open the burnout furnace door slightly for about 5 minutes to let air into the furnace. 3) Close the door, hold for about 30 minutes, then proceed with pressing. This prevents fins.

Use the standard resin cements and bonding systems used for bonding lithium disilicate restorations.

Before using Amber Glow, smooth the surface with a rubber point to increase surface smoothness; then Amber Glow will produce gloss easily.
In the high-polishing stage, polishing at low speed (about 8,000–10,000 RPM) also makes it easy to achieve gloss.

1.5–2 bar

1.5–2 bar, using 50 µm aluminum oxide

1. To remove surface texture, etc.: diamond stone points and wheels containing diamond particles, and electroplated diamond burs.
2. To adjust surface roughness: ceramic rubber points and wheels containing diamond particles.
3. To obtain gloss: Amber Glow makes polishing quick and easy.

Clean thoroughly, apply a small amount of glaze liquid to the crack, and perform crystallization firing (840 °C, 10 min); the crack line will fuse.
Deep cracks may not fuse.

Keep the drying time in the firing schedule at 6 minutes or longer.
When firing 10 or more restorations at once, extend the drying time by 2 minutes or more.

Covering discoloration with external stains is limited.
Using a white-colored cement helps cover discoloration.
We recommend removing the discolored part of the abutment in the clinic, filling it with composite resin, and then preparing the abutment.
