The Ivoclar Programat P90 Go to product viewer dialog for this item.

is a classic, high-performance ceramic furnace known for introducing the membrane-sealed keypad to the dental market in 1987. Though it is a legacy model, its reliability makes it a staple as a backup or primary unit in many laboratories for glazing and firing ceramics.  Core Specifications  The

was designed for precision and ease of use, featuring a micro-processor control and a numeric keypad for data entry.  Programs: 90 available programs for various firing cycles.

Display: Features a 7-segment display for essential parameters.

Physical Specs: Weighs approximately 16.5 kg (furnace) with a footprint of roughly mm. Power: Operates on 220V with a 50/60 Hz pulse rate.  Essential Manual & Operation Tips  Programming the involves selecting specific parameters via the keypad:  Stand-by Temperature: Can be programmed between and . Holding Time: Input in tenths of a minute (e.g.,

= 6 seconds); times between 10–30 minutes are entered in one-minute steps.

Vacuum Check: Ensure the vacuum indicator is in the green sector for proper operating vacuum. Emergency Opening: If the actual temperature is at least

, depressing the [B] key should open the furnace head within 30 seconds.  Troubleshooting & Maintenance 

Maintaining an older P90 requires attention to mechanical and electronic shifts over time.  ivoclar programat p90 manual fixed

Calibration: Temperature characteristics can shift due to contamination. It is recommended to recalibrate periodically using an independent system or the ATK2 Temperature Checking Set.

Vacuum Loss: Often caused by a contaminated vacuum valve or O-ring. Weekly cleaning of the firing plate and head seal is recommended.

Manual Head Issues: Never force the furnace head shut manually; this can damage high-torque electric drive motors. If the head stalls, check for obstructions or perform a factory reset to re-align sensors.

Dehumidification: Run a dehumidification program if moisture enters the chamber, which typically happens if the head is left open while the unit is off.  Programat®

It seems you are looking for a specific service or repair part for the Ivoclar Programat P90 furnace, likely a "fixed" component (e.g., a fixed heating element, fixed thermocouple, fixed firing tray, or a fixed software part). The phrase “manual fixed piece” is ambiguous, so here are the most likely interpretations and where to find help:

1. Indications for Use in Fixed Prosthetics

The P90 is not a standard glazing furnace; it is a high-temperature processing unit.

• IPS e.max Press: Pressing lithium disilicate ingots for crowns, inlays, onlays, and veneers.
• IPS e.max ZirCAD: Sintering pre-sintered zirconia frameworks.
• Noble Alloys (Optional): With specific accessories, it can be used for pressing certain metal ceramics, though this is less common.

General fixed-restoration programs (typical parameters)

Note: These are example baseline settings; always confirm with material/furnace-specific firing charts.

• Dentine/Body (main sintering)

  • Rate (°C/min): 60–80
  • Temp (°C): 900–960 (common range; many leucite/fluorapatite & lithium disilicate bodies ~ 900–930; check material)
  • Hold time (s): 30–90
  • Vacuum: start at peak or post-peak depending on material (check instructions)

• Glaze

  • Rate: 60–120
  • Temp: 700–760
  • Hold: 30–60 s
  • Vacuum: none or light; follow glazing paste instructions

• Muffle/Crystallization (e.g., lithium disilicate)

  • Rate: 60–80
  • Temp: 800–860 (crystallization schedules vary; many LiSi require ~820–840°C)
  • Hold: 7–30 minutes (material-specific)
  • Vacuum: typically off or as specified

• Stain firing

  • Rate: 120–200
  • Temp: 700–760
  • Hold: 30–60 s
  • Vacuum: usually off

Conclusion: Mastering Your Programat P90

The search for "ivoclar programat p90 manual fixed" usually stems from a moment of frustration—a stuck muffle, a failed vacuum, or a lost manual. However, armed with the information above, you can confidently operate your furnace in manual mode, diagnose and fix common mechanical and electrical errors, and perform a factory reset to restore baseline functionality.

Remember: A "fixed" P90 is not just one that works again, but one that is properly calibrated and maintained. Bookmark this guide, perform your monthly maintenance, and your Programat P90 will deliver thousands of flawless e.max pressings.

Introduction: The Gold Standard in Pressable Ceramics

The Ivoclar Vivadent Programat P90 is widely regarded as the workhorse of the modern dental laboratory. Specifically engineered for the press-molding of IPS Empress and IPS e.max lithium disilicate ceramics, this furnace combines high-temperature precision with user-friendly programmability.

However, even the most reliable equipment can encounter issues. One of the most searched phrases among dental technicians is "Ivoclar Programat P90 manual fixed" — a term typically associated with two critical scenarios:

1. Operating the furnace manually (bypassing automatic programs).
2. Fixing a furnace that is "stuck" or non-responsive (error codes, display freezes, or mechanical jams).

This article serves as a complete resource. We will explore how to run the P90 in manual mode, provide a step-by-step troubleshooting guide to fix common error states, and explain how to perform a factory reset (a "fixed" state).

Part 5: Recalibration – The Professional "Fixed" State

Sometimes "fixed" means calibrated. The P90 drifts over time. To fix temperature inaccuracies:

1. Go to System Menu > Service > Calibration.
2. Place a calibrated thermocouple (type S) inside the muffle.
3. Follow the on-screen prompts to fire at 500°C, 700°C, and 950°C.
4. The furnace will calculate offsets and store them.

Without calibration, even a manual firing will be incorrect.
