Advanced Sintering Process
Multilayer zirconia in just 120 minutes. Maximum aesthetics. Minimum processing time.
With the Advanced Sintering Process (ASP), you reduce the complete sintering process of conventional multilayer zirconia from “cold to cold” to just 120 minutes – reproducibly, economically, and without loss of quality.
Only 2 hours instead of 8 to 10 hours.
The system expansion, consisting of the ASP program for the NOVA furnaces and the NOVA capsule cooling unit, enables the maximization of result quality for multilayer zirconia in the absolute shortest time.
Classic sintering process: Long cycle times, blocked furnace capacity, and high energy costs.
ASP process: Faster furnace release, more flexibility, and economical same-day workflows.
Why ASP?
→ Only 120 minutes from “cold to cold”: From the start of the sintering process to the hand-warm zirconia restoration
→ Maximum aesthetic quality: Optimal translucency, chroma, and gray value representation for conventional multilayer zirconia
What advantages does the technology offer for the furnace?
→ More productivity in the lab: More sintering cycles per day and faster furnace availability
→ Process-reliable & reproducible: Patented interaction between the ASP program and NOVA capsule
Maximum material performance – without compromise
ASP was specifically developed to unleash the full potential of modern multilayer zirconia materials.
The specially coordinated ASP program ensures:
- high translucency
- precise color effect
- optimal intensity
- reproducible results
Pritidenta® is the first manufacturer to have certified this process. Other manufacturers are currently in the validation phase.
More efficiency for your dental laboratory
ASP not only improves processing time but the entire workflow.
How ASP works
1. Start ASP program
The specially coordinated program controls the optimized sintering process.
2. Removal at 1,100 °C
The sintering tray is transferred into the NOVA capsule with special tongs.
3. Controlled cooling
The restorations cool homogeneously and gently outside the furnace.
4. Further processing after a total of approx. 120 minutes
The zirconia restoration is hand-warm and ready for the next processing step.

Details, Technology & Background:
What advantages does ASP offer in daily lab work?
- The result quality is maximal in terms of translucency, gray value, intensity, chroma of conventional multilayer ZrO2
- The process time is reduced to 120 minutes instead of 8-10 hours
- Controlled, homogeneous, and material-friendly cooling outside the firing chamber produces safe and perfect results
- No thermal stress, no loss of quality -> trays last longer, objects are safe
- The furnace is available significantly faster, allowing more cycles per day, higher productivity
- Reduced energy consumption due to shorter times
- Plannable same-day concepts economically feasible
- Maximum material performance without loss of quality
What does "cold to cold" mean?
This refers to the period from placing the loaded sintering tray until the hand-warm, ready-to-process zirconia restoration.
Are there quality differences compared to long-term sintering programs?
ASP was developed to enable maximum material performance with significantly reduced processing time – reproducibly and without aesthetic compromises.
ASP was specifically developed for conventional multilayer zirconia. Initial materials have already been validated, and other manufacturers are currently in the validation phase.
What advantages does the technology offer for the furnace?
Through targeted oxygen input, the protective oxide layer of the MoSi₂ heating elements regenerates automatically. This reduces maintenance and supports a longer lifespan of the components.
At the same time, energy consumption is significantly reduced compared to classic long-term processes.
Why does the cooling phase play such an important role?
The quality of zirconia is not only influenced by heating. Controlled cooling also has a decisive impact on translucency, color effect, and material tension. This is precisely where the NOVA capsule comes in. Because ASP additionally optimizes the crucial cooling phase: controlled, homogeneous, material-friendly, and outside the firing chamber. This reduces thermal stress and ensures the optical quality of the restorations.
More efficiency. More quality. More possibilities.
