3.2 Intended use
Intended use
Indications for use
The Sirona Dental CAD/CAM System is intended for use in partially or
fully edentulous mandibles and maxillae in support of single or multiple-
unit cement retained restorations. 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 implants
systems:
● Nobel Biocare Replace (K020646)
● Nobel Biocare Branemark (K022562)
● Friadent Xive (K013867)
● Biomet 3i Osseotite (K980549)

4.3.2 ESD protective measures
ESD protective measures
ESD ESD stands for ElectroStatic Discharge.
ESD protective measures ESD protective measures include:
● Procedures for preventing electrostatic charge build-up (e.g. air
conditioning, air moistening, conductive floor coverings and non-
synthetic clothing)
● Discharging the electrostatic charges of your own body on the frame
of the UNIT, the protective ground wire or large metallic objects
● Connecting yourself to ground using a wrist band.
Training We therefore recommend that all persons working with this system be
instructed on the significance of this warning label. Furthermore, they also
should receive training in the physics of electrostatic discharges which
can occur in the practice and the destruction of electronic components
which may result if such components are touched by electrostatically
charged USERS.
The content of this training is explained in the Chapter "About the physics
of electrostatic charges" [ → 16].
CAUTION
Connector pins or sockets bearing ESD warning labels must not be
touched or interconnected without ESD protective measures.

4.3 Electrostatic charge Operating Instructions for the Acquisition Unit Sirona Dental CAD/CAM System
4.3.3 About the physics of electrostatic charges
About the phy sics of electr ostatic charges
What is an electrostatic charge? An electrostatic charge is a voltage field on and in an object (e.g. a human
body) which is protected against conductance to ground potential by a
nonconductive layer (e.g. a shoe sole).
Formation of an electrostatic charge
Electrostatic charges generally build up whenever two bodies are rubbed
against each other, e.g. when walking (shoe soles against the floor) or
driving a vehicle (tires against the street pavement).
Amount of charge The amount of charge depends on several factors:
Thus the charge is higher in an environment with low air humidity than in
one with high air humidity; it is also higher with synthetic materials than
with natural materials (clothing, floor coverings).
The following rule of thumb can be applied to assess the transient
voltages resulting from an electrostatic discharge.
An electrostatic discharge is:
● perceptible at 3,000 V or higher
● audible at 5,000 V or higher (cracking, crackling)
● visible at 10,000 V or higher (arc-over)
The transient currents resulting from these discharges have a magnitude
of 10 amperes. They are not hazardous for humans because they last for
only several nanoseconds.
Background Integrated circuits (logical circuits and microprocessors) are used to
implement a wide variety of functions in dental/X-ray/CAD/CAM systems.
The circuits must be miniaturized to a very high degree in order to include
as many functions as possible on these chips. This leads to structure
thicknesses as low as a few ten thousandths of a millimeter.
It is obvious that integrated circuits which are connected to plugs leading
outside of the unit via cables are sensitive to electrostatic discharge.
Even voltages which are imperceptible to the user can cause breakdown
of the structures, thus leading to a discharge current which melts the chip
in the affected areas. Damage to individual integrated circuits may cause
malfunction or failure of the system.
To prevent this from happening, the ESD warning label next to the plug
warns of this hazard. ESD stands for ElectroStatic Discharge.
NOTICE
Electrostatic discharge must be preceded by electrostatic charging.

4.4 Wireless phone interference with equipment
Wireless phone int erference with equ ipment
The use of mobile wireless phones in practice or hospital environments
must be prohibited to ensure safe operation of the unit.
4.5 Disturbance of data transmission
Disturbanc e of data transm ission
Note on wireless communication Data communication between the acquisition unit and the CEREC MC XL
milling unit should preferably be implemented via the wireless H&W
interface or WLAN. As for all wireless connections (e.g. mobile
telephones) 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.
Sirona has selected the best possible configuration for data
communication via the wireless H&W interface or WLAN, which generally
provides 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 H&W wireless
interface connection and instead connect the LAN cable with the CEREC
MC XL milling unit.

outside of the patient area (radius of 1.5 m surrounding the patient).
● An RS232 isolator compliant with EN 60 601-1-1 with a dielectric
strength of at least 1.5 kV must be installed at the modem end in the
RS232 connecting cable between the acquisition unit and the
modem.
