The correct sequence for a Class I amalgam restoration tray follows the order of use based on the typical procedure for placing the restoration. Initially, the excavator is used to remove any decay or debris from the cavity preparation, ensuring a clean site for the amalgam. Following this, the condenser is utilized to pack the amalgam material into the prepared cavity, which is crucial for achieving a proper fill and density in the restoration.

After the amalgam is adequately condensed, the discoid-cleoid instrument can be employed to shape the occlusal surface and create the necessary anatomy for proper occlusion. Finally, once the restoration is completed and set, the burnisher can be applied to smooth the surface of the amalgam for a polished finish. This sequence ensures both the integrity and functionality of the restoration.

Understanding the order of these tools and their specific functions helps dental assistants perform tasks effectively and contributes to better patient outcomes.
