Zenotec sintering programs
For the sintering process in the Zenotec high-temperature furnaces, the following points should be observed:
If a standard program is used, it is recommended to sinter the restorations on a sintering support base plate under a high-purity

cover. This arrangement helps prevent deformation and discolouration from occurring in the restoration. All standard
sintering programs are matched to this configuration.
If a fast sintering program is used, only the sintering support base plate - without the cover - must be used. Fast sintering is only
suitable for single-tooth restorations.
Check sintering auxiliaries regularly to make sure that they are clean and work properly.
