Operating Instructions (valid for USA) Sirona Dental CAD/CAM System
3.2
Intended use
The Sirona Dental CAD/CAM System is intended for use in partially or
fully edentulous mandibles and maxillae in support of single or multipleunit cement retained restorations. For the SSO 3.5 L and SBL 3.3 L
titanium bases, the indication is restricted to the replacement of single
lateral incisors in the maxilla and lateral and central incisors in the
mandible. The system consists of three major parts: TiBase, inCoris
mesostructure, and CAD/CAM software. Specifically, the inCoris
mesostructure and TiBase components make up a two-piece abutment
which is used in conjunction with endosseous dental implants to restore
the function and aesthetics in the oral cavity. The inCoris mesostructure
may also be used in conjunction with the Camlog Titanium base CAD/
CAM (types K2244.xxxx) (K083496) in the Camlog Implant System. The
CAD/CAM software is intended to design and fabricate the inCoris
mesostructure. The inCoris mesostructure and TiBase two-piece
abutment is compatible with the following implant systems:
● Nobel Biocare Replace (K020646)
● Nobel Biocare Branemark (K022562)
● Friadent Xive (K013867)
● Biomet 3i Osseotite (K980549)
● Astra Tech Osseospeed (K091239)
● Zimmer Tapered Screw-Vent (K061410)
● Straumann SynOcta (K061176)
● Straumann Bone Level (K053088, K062129, K060958)
● Biomet 3i Certain (K014235, K061629)
● Nobel Biocare Active (K071370)
CAUTION

4.3
Wireless phone interference with equipment
The use of mobile wireless phones in practice or hospital environments
must be prohibited to ensure safe operation of the unit.
4.4
Disturbance of data transmission
Note on wireless communication
Fragment Worldwide
Data communication between the acquisition unit and the CEREC MC/
MC X milling and grinding unit should preferably be established via the
wireless interface CEREC Radio Device or WLAN.
As for all wireless connections (e.g. cell phones), heavy utilization of the
available radio channels or shielding caused by building installations (e.g.
metal-shielded X-ray enclosures) may impair the quality of the
connection. This may become noticeable through a reduction in range
and/or a slower data transmission rate. In extreme cases, it will be
impossible to establish a wireless connection at all.
Dentsply Sirona has selected the best possible configuration for data
communication via the wireless interface (CEREC Radio Device) or
WLAN, which generally ensures perfect functioning of this connection.
However, in individual cases unrestricted wireless data communication
may be impossible for the reasons mentioned above and/or due to local
circumstances. In such cases, a cable LAN connection should be
selected to ensure uninterrupted operation. If the only LAN interface on
the rear of the CEREC AC is occupied by another plug, remove this
wireless interface connection, and instead connect the LAN cable with the
CEREC MC/MC X milling and grinding unit.
CAUTION
Instruments that continue to run
When the processing chamber door is opened during the machining
process, the instruments could continue to run for a short time.
➢ Be careful not to touch the instruments with your hand or any other
object during this time.
➢ Avoid opening the processing chamber door while the milling and
grinding unit is in operation.
➢ Before you open the processing chamber door, end any actions that
are running by pressing the
"Stop"
button on the milling and
grinding unit or in the application software.

5.4.7.7.2 CEREC Radio Device
Creating a network
The supplied network devices have not as yet been part of a network. To
enable several networks from various operators to be created next to one
another or in the same area, new network devices must first form a
network. This is described in the following section.
To create a new network with several new network devices, perform the
following steps:
1. Place all network devices in the same area.
2. Switch all network devices on within one minute.
3. After switching on the last network device, wait approx. one minute.
4. Make sure that all network devices are connected, as indicated by the
green LED; see section “LED displays” in the “CEREC Radio Device”
operating instructions (REF 65 45 177).
All network devices now belong to a single network, which can be
operated as an independent network, and can communicate with one
another. In the event of problems, see section “'Network creation failures”
in the “CEREC Radio Device” operating instructions (REF 65 45 177).
Extending the network - adding a new network device
New network devices can be added to an existing network. To prevent
random network devices from becoming part of the network, the user
must perform the following steps:
1. Place the new network devices next to a network device that is part
of the network.
2. Switch on the new network devices.
3. Switch the existing network device off and on again within one
minute.
After one minute the new network devices will become part of the
network.

6.4.5 Information on the seal of approval
Proper selection and processing of the material are decisive for the longterm clinical success of the restoration, especially in the case of zirconia.
However, different types of zirconia require individually matched machine
parameters. This is the reason why you can and must select different
types of zirconia in the software. These machine parameters are
coordinated between material partners in complex development
processes. In addition to the desired fit and surface quality, they also
guarantee a maximum degree of material and equipment safety.
Consistently high quality of the grinding or milling result and the fit can be
guaranteed and damage to the processing machines can be excluded
only if certified materials are used.
Fragment: Everything excluding FONA
WARNING
Risk of injury on the remainder of the ceramic block
The remaining portion of the ceramic block may have sharp edges
(e.g. A) that could injury you if it is not removed carefully.
Always grasp the remainder of the ceramic block by its metal holder.
CAUTION
Do not use defective milling or grinding results!
Machining results must be judged by the user (dentist or dental
technician) and must not be used if defects are detected!
NOTICE
If you have not used the milling and grinding unit for a rather long time,
we recommend you should switch it off and then open the processing
chamber door so that the processing chamber can dry out.
NOTICE
Block without seal of approval
If a block is found without a seal of approval during the machining
process (milling or grinding), the following message appears:
"No quality label was recognized on the block. The grinding and milling
processes as well as the instruments are specially verified for certified
materials. Certified materials can be identified by the engraved "inLab"
lettering on the block. The use of zirconium oxide materials without
quality label can lead to inferior results as well as increased wear on the
device and instruments.
Do you still wish to start the manufacturing process?"

Manual block clamp
1. Insert the block (A).
2. Clamp the ceramic block securely with the ball pressure screw (B).
Use the block clamp tool for this purpose.
The block is pressed laterally against the contact surface of the
block fixing and simultaneously pulled in axially. The plate of the
block holder thus rests on the block fixing.
NOTICE
Wear of the ball pressure screw
The high clamping forces cause wear of the ball pressure screw.
➢ Replace the ball pressure screw every 500 clamping operations.
NOTICE
Fasten the block tightly
If the block is not tightened sufficiently, this may result in falsification of
the machining result and fracturing of its ceramic material.
➢ Tighten the block securely with the block clamp tool.
➢ Check to make sure that the block is seated very firmly.

Using the cleaning hose and the wet cleaning
process
The processing chambers of devices used for dry milling of zirconium
oxide should be cleaned regularly in order to prevent deposits of
zirconium oxide dust in the chamber. A second cleaning hose with a
nozzle can be used before the wet cleaning process in order to support
the user when sucking zirconium oxide dust out of the device's
processing chamber. This hose is available separately as a spare part
(REF 65 89 795). We recommend carrying out this cleaning procedure (or
the wet milling of a restoration) at least once per week if the device is used
for dry milling of zirconium oxide.
Proceed as follows to use the cleaning hose and to execute the
recommended wet cleaning process:
1. Remove the normal hose which is connected to the milling/grinding
unit.
2. Connect the cleaning hose to the upper opening of the suction
device.
3. Activate the manual operation for the suction device by setting the
switch at the top of the device from "Auto" to "On".
4. Suck up the dust from the chamber as required.
NOTICE
Wear of the ball pressure screw
The high clamping forces cause wear of the ball pressure screw.
➢ Replace the ball pressure screw every 500 clamping operations.
