General Information
The 3M ESPE Lava C.O.S. is used to capture high-accuracy scans of human teeth. Data from
these scans are used in manufacturing oral prostheses, such as crowns, inlays, and onlays.
The main system components are:
Scanning wand – A freehand, high-accuracy video camera used to acquire three-dimensional
data in real-time. The wand’s cable connects to the cart assembly and can be detached.
Touch screen display – A touch-enabled screen used to display and control the acquired
images, scans, and video. The touch screen is also used to interact with the system software,
by entering patient information, prescriptions, and so on.
Computer – Self-contained control system that houses the processing, storage, and interface
capabilities of the unit.
Cart assembly – Provides cable management and mounting locations for the other
components. It is equipped with locking wheels for stability.

Care, Maintenance, and Handling of the Lava C.O.S.
Follow these guidelines when using the device:
• The device is to be used only by qualified operators who have been trained by 3M
ESPE.
• Keep the cooling vents, located on the rear of the Lava C.O.S., clear of lint and
debris. Do not allow the vents to be blocked.
• The air inlet slots, which are located on the side panels at the front of the Lava
C.O.S., should remain free of dust. Vacuum these slots at least annually to remove
any accumulation of dust.
• Deploy the caster locks to lock the wheels of the cart in place.
• Store and use the Lava C.O.S. within prescribed temperature, humidity, and altitude
limits. (Refer to “Equipment Specifications and Classifications.”)
Cautions and Warnings
• WARNING: Do not place the cart on a slope greater than 10 degrees.
• CAUTION: Do not break or alter any existing connections on the Lava
C.O.S., for example, the connection between the device and the display screen. The
only exception is the wand, which must be unplugged for cleaning and disinfection.
(See “Cleaning Procedures” and “Disinfection Procedures” sections below.)

3M ESPE Lava Chairside Oral Scanner User Guide - Beta page 18 of 118
Scanning wand
CAUTION: The scanning wand is a highly-precise, multiple-lens instrument.
Improper handling of the wand, such as dropping, shaking or bumping, could cause the wand
to malfunction or break. Always follow these guidelines:
• Exercise great caution when handling the scanning wand.
• Return it to one of the holsters when it’s not in use.
• Do not kink the cord that connects to the back of the wand.
• Do not submerge the wand or its cord in any liquids.
CAUTION: Examine the wand and the system (cart, screen, etc.) for physical
damage before each use. Look for any loose parts, sharp edges or signs of wear or damage
that could interfere with its proper use. Contact Customer Support if there is visible damage
or if the device does not perform as expected.
NOTE: Wands are not necessarily interchangeable among Lava C.O.S. units. If you have
more than one Lava C.O.S., you may not be able to plug in the wand from one Lava C.O.S.
unit into another unit. Contact Service and Support: 1-877-SCAN-LAVA (1-877-722-6528)
or email [email protected] if you have any questions.
Cleaning Procedures
After each patient, clean the touch screen, bezel (the border that frames the touch screen), the
body of the wand and the tether cord.

3M ESPE Lava Chairside Oral Scanner User Guide - Beta page 19 of 118
You do not need to shut down the Lava C.O.S. while cleaning its surfaces, but you may want
to log out before cleaning the monitor.
CAUTION: Pressing and holding the power button on the back of the computer
chassis to turn off the Lava C.O.S. can cause major system damage. A quick press of the
power button when the scanning interface is not displayed will cause the system to shut down
normally. It is recommended you shut down the system via the power button on the touch
screen.
Do not detach the tether cord from the wand when cleaning or disinfecting. If the
area where the cable connects to the wand should be submerged or get wet, then the cable
will need to be disconnected and the contact areas dried with compressed air.
The following agents are approved for cleaning the touch screen, bezel, wand body, and
tether cord surfaces:
• BIREX®se (by Biotrol) or equivalent
• CaviCide® (by TotalCare Kerr/Metrex) or equivalent
• Warm water and mild, non-abrasive detergent: Fantastic®, Formula 409®, Lysol
cleaner or equivalent
(70% IPA [isopropyl alcohol] can also be used to clean the touchscreen, but not the other
surfaces. Avoid contact with skin.)
_______________
BIREXse is a registered trademark of Biotril.
CaviCide is a registered trademark of Kerr/Metrex Corporation.

3M ESPE Lava Chairside Oral Scanner User Guide - Beta page 20 of 118
To clean the touch screen, bezel, wand body, and tether cord (and other cart surfaces as
needed):
1. Apply the cleaning agent to a soft, non-abrasive cloth.
2. Wring out the cloth until damp.
3. Wipe down the surfaces with the damp cloth.
4. Rinse the cloth in clean water.
5. Wipe down the surfaces a second time.
6. Dry the body of the wand and the tether cord with a clean, non-abrasive cloth. The
touch screen and bezel can air dry.
Do not spray or pour liquids on these surfaces.
Never submerge the scanning wand.
Do not use ammonia-based cleaners on these surfaces.
Disinfection Procedures
While a patient is being scanned, the wand should be barriered. Approximately one inch of
the distal tip of the wand should be exposed during scanning so that the sheath does not
obscure the lens. Follow standard barrier procedures while using the scanner.
To prevent cross-infection, the tip of the wand must be disinfected before each use. Follow
these procedures:
1. Unplug the wand from the dental workstation by pulling gently on the textured
portion of the connector from the back of the unit. (The unit itself can remain on.)
