What system accomplishes the mixing of final impression material for the assistant?

  1. Hand mixing

  2. Suction-based

  3. Auto-mix

  4. Vortex mixing

The correct answer is: Auto-mix

Auto-mix is the best option because it automates the mixing process, ensuring precise and consistent mixtures every time. Hand mixing, while it may seem simple and convenient, can lead to uneven mixtures and inaccurate results. Suction-based and vortex mixing may also provide inconsistent mixtures and are not specifically designed for final impression material mixing. Therefore, auto-mix is the most effective and reliable option for ensuring accurate and consistent final impression material mixing for the assistant.
