How do I insert and remove LOCATOR Processing Spacers in an ArchBridge Scan Body?

Why the spacer matters

Each ArchBridge Scan Body incorporates an internal interface designed to receive the applicable Zest Processing Spacer. The Processing Spacer is what provides the interface between the ArchBridge Scan Body and the Zest LOCATOR or LOCATOR FIXED abutment during intraoral use.

ArchBridge Scan Bodies are designed for use with the Zest Processing Spacer, P/N N2001657108. Do not use alternative or third-party processing spacers. They will not fit properly into the scan body and will not provide the seating and stability required for accurate positioning of the ArchBridge Scan Body.

The Processing Spacer is a single-use component. It should be discarded after use and shall not be cleaned, sterilized, reprocessed, or reused.

Inserting the Processing Spacer

  1. Select the ArchBridge Scan Body geometry appropriate for the available intraoral space and anatomy.
  2. Insert a new Zest Processing Spacer, P/N N2001657108, into the internal interface of the ArchBridge Scan Body using the insertion end of the Enhanced LOCATOR and LOCATOR FIXED Systems Core Tool, in accordance with the tool manufacturer's instructions.
  3. Verify visually that the Processing Spacer is fully inserted and flush with the ArchBridge Scan Body. The white plastic should be exactly even with the outer metal rim of the scan body.

Removing the Processing Spacer

  1. Use the Zest Enhanced LOCATOR and LOCATOR FIXED Systems Core Tool for this process.
  2. Place the non-activated removal end of the tool into the insert and rotate counter-clockwise until you feel resistance, then tighten an additional quarter turn.
  3. After the quarter turn, hold the scan body assembly in one hand while simultaneously spinning the Core Tool clockwise by the black handle with your other hand for five or six turns. This cuts a groove in the insert that secures it to the handle.
  4. While holding the scan body, pull the Core Tool away from the scan body, removing the part.
  5. Once separated, rotate the handle clockwise while holding the removed scan insert to deactivate the Core Tool and release the insert.

Handling precaution

ArchBridge Scan Bodies are small components. Take appropriate precautions during intraoral placement and removal to minimize the risk of accidental swallowing or aspiration.
