Overview

This document details the specifications, sintering procedures, physical characteristics, and indications for the 3D FLASH dental ceramic material, emphasizing its rapid sintering technology for aesthetic dental restorations.

1. Sintering Procedures and Temperature Profiles

The document presents multiple sintering curves and temperature-time profiles for different sintering cycles, highlighting rapid sintering capabilities:

• Rapid Sintering Cycle (Approx. 40 minutes): Starts at room temperature (20°C), heats at 200°C/min to 1150°C, then at 25°C/min to 1310°C, and finally at 15°C/min to 1530°C with a 15-minute hold, followed by natural cooling.
• Standard Sintering Cycles: Include longer durations such as 90 minutes and 4 hours with controlled heating rates (e.g., 12°C/min, 7°C/min, 6°C/min) and holding times (up to 120 minutes) at maximum temperatures ranging from 1500°C to 1530°C.
• Cooling: Natural cooling to room temperature is consistently applied after sintering.
