4 Introduction Planmeca Emerald User Manual
Introduction
The Planmeca FitTM System is a complete optical impression system for CAD/CAM of dental restorations intended
for dental oces or laboratories. The system comprises a Planmeca Emerald digital impression scanner, Planmeca
Romexis CAD/CAM design software module, and Planmeca PlanMill40 S mill.
The Planmeca Emerald scanner takes digital impressions which can be designed and customized on the Planmeca
Romexis CAD/CAM design software. The impressions can be sent via Planmeca Romexis Cloud to Planmeca or a
certied laboratory for design and milling or exported to a third party.
Caution: US Federal law restricts the Planmeca Emerald to sale by or on the order of a dentist.
The Planmeca Fit System requires Planmeca Romexis software revision 3.4.0.R or later.
Associated Documentation
Planmeca Romexis User’s Manual (publication number 10014593).
Throughout the documentation, important notes and items of interest are formatted like this example.
Warning The orange Warning denotes something that can cause personal injury or physical damage to the
equipment.
Some of the screenshots may have been taken in earlier software versions and may not exactly match your screen.
Indications for Use
The Emerald Optical Impression Scanner is an optical impression system used to record the topographical
characteristics of the dentition and/or full arch and preparation areas (including features such as implant scan locator
xtures, braces, brackets, etc.). In addition it can record the topographical characteristics of the oral anatomy (such as
soft tissue, gingivae and palate).
The three dimensional model generated from the scan may be further used for study models, and for the design and
manufacturing of dental restorations including implant supported prostheses and full and partial frameworks, and
can be used to design and manufacture physical models of the teeth.
It may be used in conjunction with production of orthodontic appliances, retainer and accessories.
Contraindications

8 Introduction Planmeca Emerald User Manual
Cleaning the Scanner Tip
For intraoral scanning systems only.
The following instructions are for the removable tip of the scanner. It is not for the entire scanner.
See “Cleaning the System” on page 10 for cleaning the base of the scanner.
The scanning tips have been manufactured and tested for specic disinfection protocols. Operational,
maintenance and replacement instructions should be followed for the product to perform as
designed. Cleaning the scanner tip incorrectly may result in incomplete disinfection and/or
permanent damage to the tip.
DO NOT use a chemical sterilant on tips with the autoclave symbol.
DO NOT place in Ultrasonic Cleaner.
DO NOT pouch with other instruments.
DO NOT stack the tips near or on any other metal instruments.
Excessive cycle times may prematurely reduce the life and function of the tip.
1 Remove the scanner tip from the scanner.
2 Rinse and brush the external surface of the tip under warm running water (3-3.5L/min @ 30°-35°C [86°-95°F])
for a minimum of 15 seconds, with emphasis on the tip alignment indicator. Use a soft bristled brush, like a soft
toothbrush.
To prevent scratches, avoid brushing the mirror.
A typical water faucet should be able to produce a ow rate of between 4-8 Lpm.
3 Rinse and brush around the edge and surrounding crevices of the mirror under running water for a minimum
of 30 seconds. To avoid scratching the mirror, use a soft bristled brush. Be careful that only the bristles are
in contact with the surface of the mirror.
The example picture is shown without running water for visibility purposes. Use the bristles of the small brush on all
crevice edges of the mirror. (ex. Pinn-Point Brush 933-0321 shown)
4 After brushing, rinse the mirror and surrounding crevices under running water for an additional 15 seconds.
5 If there is any visible debris remaining after performing the cleaning steps above, repeat the process as necessary
until the tip is visually clean. If there is any debris that cannot be removed or, if there is visible deterioration such
as cracks or discoloration, the tip should be properly disposed of and replaced.

15698200.B Introduction 9
6 Individually pouch each scanner tip using an autoclave pouch (ex. HSD # 112-4854 or a comparable product).
Autoclave baskets are not indicated for this cleaningprocedure.
7 Place one to three pouches per tray or cassette. DO NOT stack tips on or around other metal instruments.
8 Select the Wrapped, Wrapped Instruments, or Pouch cycle on the autoclave with a minimum cycle of 132°C
(269° F). Minimum sterilization time of 3minutes for Pre-Vac autoclaves. Minimum sterilization time for Gravity
autoclaves is 10 minutes. For any autoclave, use a minimum dry time of 10 minutes.
These cycle times are for pre-vacuum autoclaves. Autoclave cycle names dier among manufacturers.
Autoclave sterilization cycle times exceeding 10 minutes could be considered excessive and may damage
the internal components and pin connector points. Referenceyour manufacturer’s manual to select the
cycle for sterilizing wrappedinstruments.
9 Prior to scanning, visually conrm the scanning mirror and scanner connection points of the scanning tip are
clean and dry. To clean either surface, use an optical cloth or 2x2 gauze with a small amount of alcohol to gently
remove residue. Ensure each surface is dry before connecting it to the scanner.
Storage
1 Wipe water o mirror using non-woven optical wipes (recommend Kimwipes Lens Cleaning #101-7070).
2 Optional: Insert tip into a sterilization pouch. (recommend Self Seal Sterilization Pouch 5 ¼”x 10” [200/box] #112-
4854)
3 Store for later use.
4 Prior to scanning, visually conrm the scanning mirror and scanner connection points of the scanning tip are
