After repairs, the following tests were conducted:
Select the automated Silver Calibration Program from the P90 menu interface.
: Use an ATK2 calibration set to verify firing accuracy. Insert the ATK2 sample into the furnace and run the dedicated calibration program.
The Ivoclar Programat P90 is a highly advanced dental furnace designed for the fabrication of fixed dental prosthetics. This state-of-the-art equipment has revolutionized the dental industry with its precision, accuracy, and reliability. In this article, we will provide an in-depth look at the Ivoclar Programat P90 manual and explore its features, benefits, and applications in fixed dental prosthetics.
Compatibility: Optimized for Ivoclar Vivadent ceramic systems but compatible with all standard porcelains.
: With 90 programmable settings, it offers consistent performance for glazing and firing ceramics, specifically matched to Ivoclar's own materials. Compact Design
: Press STOP once to cease movement and sound indicators. If the head remains locked, disconnect power. Locate the manual hinge alignment pins on the rear arms. Gently ease the vertical lift rod down. Do not force it by hand as it can damage the internal drive gear. 🎚️ Manual Thermal Calibration (The Silver Wire Test)
Inspect the main black rubber O-ring located on the lower firing tray matrix. Clean it with a lint-free cloth and apply a micro-layer of high-temperature vacuum grease. If the rubber appears cracked, brittle, or flattened, replace the O-ring immediately.
Once the cycle finishes and the chamber opens, inspect the silver wire immediately:
What triggers the error (e.g., starting a program, opening the lid)
: This error appears if the pre-set vacuum switch-off value exceeds the pre-set temperature (
The , originally released in 1987 , is a landmark in dental furnace history as the first model to feature a membrane-sealed keypad . While it is a vintage machine by today's standards, its robust build quality has kept it in use in many laboratories for decades. Core Specifications
