Zirconia teeth are light, not transparent enough, and white after sintering

Possible reason analysis a problem with the sintering process or the sintering furnace. Insufficient crystallization time will cause problems such as under-cooking and whitening of zirconia (the main crystallization temperature is between 1000-1450, the heating speed is slow, and at least 120 minutes of heat preservation is required). If the sintering temperature is too high, the dyeing effect will become lighter. First confirm whether the sintering program used by the customer is the standard sintering curve provided by us, and then confirm whether the customer’s sintering furnace has problems such as unstable temperature field or uncleaned for a long time. If necessary, check the temperature field, or suggest that the customer replace the sintering furnace for sintering . The teeth are not dried during the dyeing process, resulting in uneven local staining, and the residual water in the teeth may cause a large difference in local temperature of the teeth, resulting in insufficient local crystallization or cracks.

Cracks or fractures in teeth or long bridges after sintering. Possible reasons analysis

Due to the abnormality of the bur or engraving machine, cracks in the restoration were not found during the cutting process or re-grinding process, resulting in fracture after sintering.

Problems such as fracture and porcelain collapse during the cutting of zirconia

The customer's tool has been used for too long, the customer's engraving machine has been uncalibrated for a long time, or the spindle has been deviated, and the restoration design has problems

Can the sintering curve be modified?(Change 6 steps into others)

Yes. Since the sintering machine used by individual customers cannot complete the 6-step sintering setting, we can modify it to 4 steps according to the guidance of the project department. But it is necessary to control the sintering temperature and time.
