Electronic Temperature Monitoring: Features a digital display for real-time monitoring of the firing process, allowing technicians to verify that the furnace is following the programmed curve precisely. Ivoclar Programat P90 Manual

B. Calibration (The "T" Setting)

If your crowns are coming out under-fired or over-fired, you likely need to calibrate. The Ivoclar Programat P90 Go to product viewer

Temperature Calibration: Like all dental furnaces, it requires periodic calibration to maintain accuracy. While newer models use automatic ATK2 systems, the P90 era often relied on manual silver wire tests. Ventilation: The P90 requires a minimum of 10

• Ventilation: The P90 requires a minimum of 10 cm (4 inches) of free space on all sides and above for heat dissipation. Installing it under a low shelf without the specified gap will lead to overheating and premature electronic failure.
• Leveling: The furnace feet are adjustable. An unlevel furnace can cause uneven press pressure, resulting in incomplete or lopsided restorations. The manual includes a spirit level check procedure.
• Initial Heat-Up (Bake-Out): Before first use, the manual specifies a special “Bake-out” program to burn off manufacturing residues from the heating elements. Skipping this can release odors and potentially contaminate first restorations.

Who is this for?

1. The "Old School" Technician: If you prefer tactile control and do not want a furnace that automates everything, the P90 offers the perfect balance of control and technology.
2. High-Volume Labs: A lab that needs to run 10-15 press cycles a day without worrying about the machine overheating or failing.
3. Budget-Conscious Startups: Buying a used P90 is often a smarter investment than buying a cheap, brand-new Chinese-import furnace.

The Definitive Guide to the Ivoclar Programat P90 Manual: Operation, Calibration, and Mastery

In the world of dental ceramics, precision is not just a goal; it is a requirement. The Ivoclar Programat P90 is widely regarded as the gold standard furnace for firing high-performance glass-ceramics, specifically lithium disilicate (IPS e.max). However, owning this sophisticated piece of equipment is only half the battle. The true power of the furnace lies in understanding its operational manual.

Precision Control: It was the first in the series to include a 7-segment display and a numeric keypad, allowing technicians to easily select and modify any of its 90 built-in programs.
