Firing of lithium disilicate glass-ceramic (LS

)-supported restorations

– Use the honey-combed ﬁring tray and the corresponding support pins to ﬁre the restorations.

– Do not use ceramic pins, since they may stick to the restoration.

– The processing temperatures must be observed. Increasing the ﬁring temperature will result in severe vitriﬁcation

between the framework and the veneering ceramic, which may lead to crack formation later on. Reducing the ﬁring

temperature results in the ceramic being underﬁred rendering it very brittle, which may ultimately lead to delamination.

– The parameters in the Instructions for Use apply to Ivoclar Vivadent furnaces (tolerance: +/- 10 °C/18 °F)

– If furnaces other than those from Ivoclar Vivadent are used, temperature adjustments may be necessary.

– At the beginning, open the furnace and wait for the acoustic signal. Subsequently, place the ﬁring tray with the objects

in the center of the ﬁring table and start the program.

– Remove IPS e.max objects from the furnace after completion of the ﬁring cycle (wait for the acoustic signal of the

furnace).

– Allow the objects to cool to room temperature in a place protected from draft.

– Do not touch the hot objects with metal tongs.

– Do not blast or quench the objects.

Depending on the furnace type, the ﬁring temperature can be reduced by 5 °C to max. 10 °C (9 °F to max. 18 °F) for the

Dentin / Incisal ﬁring.
