2.1 Indications for 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:

Software
3.1 CEREC Biogeneric
CEREC Biogeneric is the first method which is able to reconstruct lifelike
occlusal surfaces. On the basis of the features of a patient's single intact
tooth, the program extrapolates the naturally created morphology of other
teeth. The biogeneric occlusal design functions for all single tooth restorations and fully anatomic bridges.
Currently, all occlusal design approaches are based on dental libraries
and databases containing data records of various standard teeth. Conventional CAD/CAM programs retrieve a matching tooth from the archive,
and then generate a design proposal for the given clinical situation. The
user then manually edits and adapts this proposal. The biogeneric occlusal design is to replace the “dental database” design procedure applied in
previous CEREC software versions. It will now be possible to create
crowns, inlays, onlays, veneers, and anatomically sized bridges in a fully
automated manner. The reconstruction can be based on any intact patient tooth from the same type, i.e. posterior tooth or anterior tooth. The often time-consuming process of manually adjusting the tooth to the clinical
situation is now virtually a thing of the past. Moreover, due to the standardized and largely automated routines, the new software is easy to get to
grips with and use.
3.2 System requirements

Design window (3D viewer)
inLab 3D contains a main window (3D viewer) for visualizing and designing a restoration in 3D.
The 3D viewer opens after all image fields have been acquired. The time
up to display of the viewer depends upon the number of image fields and
the number of single optical impressions.
You can do the following in the Design window:
● view the image fields of the preparation, of the occlusion and of the
antagonists as well as the restoration, either individually or in any
combination,
● determine a new insertion axis,
● hide an image region by entering an open line mesially and distally,
● enter the preparation margin,
● immediately see the effects caused by applying a tool (e.g. editing,
scaling ...)
● view the restoration in the milling simulation before machining,
● rotate the objects arbitrarily. To do so, press and hold down the left
mouse button and move the mouse in the desired direction.
● For better orientation, the direction is indicated (e.g. mesial, lingual,
etc.).
The objects are displayed centered. You can change the position of the
objects with the right mouse button pressed.
4.7.2
Scale
The scale is displayed in the bottom left corner of the 3D viewer. The distance between A and B corresponds to 1 mm.

NOTICE
No contact to the neighboring tooth
If the neighboring tooth is located at a distance of more than 1mm (e.g.
neighboring tooth prepared), no contact is made.
The setting of the parameter "Proximal contacts strength" affects crown,
inlay and onlay restorations.
If you find that the contacts proposed by the software are generally too
strong or too weak, you can change them via the menu "Settings"/"Parameters..." according to your requirements.
If you set a higher number in the "Proximal contacts strength" text box,
correspondingly more material will be applied to the contact points.
The thickness of the contact points can be adjusted in increments of
25µm between -200µm and 200µm.
NOTICE
Change only after recalculation
This setting acts only on line suggestions. A change to this setting becomes effective only after recalculation of the suggestion.
NOTICE
Inadequate suggestions for contact points
The proximal contact points are determined by the software by analyzing your measured data. Poor quality of the acquisition data can lead
to inadequate suggestions regarding the contact points.
The setting of the parameter "Proximal contacts strength" has no influence on the design of crown and bridge frameworks.
4.8.3.1.2
Occlusal contacts strength
With this parameter you can set the contact thickness to be produced in
connection with "Virtual grinding".
The thickness of the contact points can be adjusted in increments of

4.8.3.1.3
Occlusal offset
If you find that all of your restorations have too little or too much material
in the occlusal direction, you can compensate for this with this parameter.
The occlusal offset can be adjusted in increments of 25µm between 500µm and 500µm.

Adhesive gap
Description
If you find that all of your inlay restorations turn out to be too large, you
can compensate for this by modifying the adhesive gap.
If you set a larger number in the "Adhesive gap" text box, the adhesive
gap will be enlarged correspondingly. The size of the adhesive gap can
be varied in increments of 10 µm from 0 µm to 150 µm.

5.1 Scans with inEos Blue
5.1.1
General
Acquisition methods
You have three modes for executing scans with inEos Blue:
● Grid acquisition
–
For large scans with 9 or more units
–
Long, untoothed areas
● Free scan
–
For scans with up to and including 8 units
–
For additional scans at different angles
● Rotational scan
–
For the surveying of single tooth stumps
–
For single restorations without consideration of the proximal contacts or the antagonist
You can execute several scan modes in sequence.
You can omit a scan mode if, for example, it is not suitable for your model.
5.1.1.1
Scan models
Materials
You can scan all materials that correspond to the following criteria:
● Non-reflecting
● Nontransparent
● No transparent parts
● Not highly absorbent
(e.g. heavily colored plasters)
Unscannable materials generate artifacts in the image.
Tip: When using plasters that do not meet the above criteria, you must
powder the affected areas. Otherwise the measuring accuracy will be impaired considerably.
The following are suitable for this purpose: CEREC Optispray (REF
61 44 179)
For scanning with inEos Blue, we recommend using CEREC Stone BC
plaster (REF 62 37 502).
● When preparing saw-cut models, be careful not to mill off the single
stump segments. Place the model next to the stumps so that the
scanner can properly capture these areas.
Saw-cut etc.
● Create only a slight fluting below the preparation margin.

Rotational scan in top view
Increasing the precision
You can increase the precision by combining the top view with one or
more rotational images instead of with individual detail scans. This applies especially in the vicinity of preparation borders on tooth stumps serving as bridge abutments.
5.2.4.2
1. Remove the prepared single teeth intended for the rotational scan
from the saw-cut model.
2. Place the single teeth in the model holder in succession and align
them as coaxial as possible (i.e. ideally the insertion axis would coincide with the rotation axis) as for the individual rotational scan also.
3. Perform the rotational scans (see chapter "Rotational scan [ ➙ 103]“).
4. Reassemble the saw-cut model.
5. Align the complete saw-cut model in the holder just as you would for
top view scans without a rotational scan. The saw cuts should be
filled (e.g. with powdered wax) to prevent needle artifacts, etc., on the
cuts.
6. Take the top view scan (see "Top view scan [ ➙ 101]“).
5.2.4.3
Further information
Insert the model holder with the stump positioned so that the mesio-distal
alignment of the single tooth corresponds to the alignment of the complete model (also see "Rotational scan [ ➙ 103]"). This speeds up the calculations.
NOTICE
Take few scans
Take as few scans as possible: The program is suitable for any typical
applications – e.g. for two rotational scans combined with one top view
comprising 4-6 individual scans.
Whole-jaw scans combined with more than four rotational scans are
possible, however, they are not advisable due to the high memory requirements and long calculating times involved.

5.5 Image fields
Introduction
An image field can consist of one or more optical impressions.
We distinguish between the following image field types:
Image field types
● Image field of the preparation
● Image field of the buccal image
● Image field of the occlusion
● Image field of the antagonists
● Image field of the articulation
Waiting times
NOTICE
Waiting times
If a large number of optical impressions is used (>50), longer waiting
times may result during reconstruction of the 3D model. The files become very large.
Generally, the following applies: As many optical impressions as necessary, but as few as possible.
5.5.1
Image field of the preparation
Description of individual teeth
Optical impressions can be made of the prepared tooth/teeth in the image
field of the preparation.
5.5.2
Image field of the occlusion
Description
In the image field of the occlusion, optical impressions of a previously existing or of a waxed-up occlusion are possible.

Optical impression
Operator's manual
The image field of the occlusion must agree with the image field of the
preparation in the mesial and distal region.
inLab
Even if you are not using the "Correlation" design technique, a mock-up
can be scanned here as a design aid (e.g. set-up teeth). This scan can be
displayed as a reference image during the design process.
NOTE replication
In the "Biogeneric reference" design technique, the exposures of the replicate must lie within the image field of the occlusion.
5.5.3
Image field of the buccal image
These impressions are possible only if you have selected the following in
the New dialog box: "Bite registration technique" > "Buccal scan".
An exposure in which 50% of the image contains the upper jaw and 50%
of the image contains the lower jaw is usually sufficient in most cases. In
order for the registration to succeed, it is important to ensure that the relevant image information for the preparation and the antagonist show sufficient a buccal proportion.
5.5.4
Image field of the gingiva
Here you can take images of the gingiva. The scanbody can be removed
for these exposures. Alternatively, it is possible to copy the relevant exposure from the image field preparation.
5.5.5
Image field of the antagonists
Description
In the image field of the antagonists, scans of a centric bite registration or
the opposite jaw are possible.
5.5.6
Image field of the articulation
Optical impressions of a dynamic occlusion impression (FGP technique)
are possible in the image field of the articulation. These impressions are
possible only if you have selected the following in the New dialog box:
● "Restoration": "Crown"
● "Design technique": "Articulation"

6.4.1
Preparing the right insertion axis
CEREC Biogeneric obtains the information it requires from the occlusal
surface and the proximal contact line of adjacent teeth. During the acquisition procedure, all the essential information is recorded based upon the
insertion axis specified by the user: The software stipulates that both levels must be positioned vertically to the insertion axis. If indentations are
created by positioning the insertion axis vertically to the occlusal surface
in the preparatory steps, you must change the direction of the insertion
axis. Deviations of the acquired surface from the actual occlusion have a
negative effect upon the quantity of data available for the biogeneric algorithm. This has the potential to affect the quality of the proposal.

folders in which the individual restoration files are stored.
If the database connection is used, the "PDATA" folder (created during installation of the SIRONA database) contains a folder named "CEREC".
Since a unique patient number is assigned to each patient in the database, no patient names are used here under "CEREC"; instead, consecutively numbered folders (e.g. “P_000001”) are listed. The tooth folders
and restoration files can be found below them.
8.6 Consistency check
If the database connection is active, a consistency check will be performed when the inLab 3D application is started. The database will be searched for images from earlier inLab 3D versions. Any such old images
found will be updated. The user is informed of the progress.
If the list of restorations for a specific patient is displayed for loading or
deletion, corrupt restoration files will automatically be recognized and
suggested for deletion.
This mechanism always remains active, regardless of whether a database is connected or not.

In the "New" dialog, first select the following:
● "Restoration"
● "Bite registration technique"
● "Design technique"
On the virtual model, then select the tooth positions that you want to design.
Different design techniques are available depending on which restoration
type you choose. For example, a restoration for an implant can be designed using the design technique "Mesostructure" or "Biogeneric".
You can use "Bite registration technique" to select how the antagonist for
the relevant jaw is moved to the centric jaw relation. The upper and lower
jaws can usually be brought together using one buccal exposure. If you
want to work with a conventional bite register, select "Bite material scan".

9.4 Biogeneric
9.4.1
Introduction
In the "Biogeneric"/"Individual" design technique, the neighboring teeth
are analyzed and the restoration suggestion is calculated on this basis.
The more information that is available, the more successful the calculation. A full image of at least one neighboring tooth should therefore be taken from the occlusal/incisal direction. For anterior and corner teeth, an
image of the labial surface should also be taken.
For premolars or molars, the calculation is mainly based on the distal
neighbor, for anterior teeth the mesial neighbor is used.
NOTICE
If larger regions of the neighboring teeth already have restorations or
are prepared, this calculation is severely restricted. A suggestion is also
generated, which corresponds, however, to an average tooth that has
not been optimally adapted to the residual teeth. If a suitable neighbor
cannot be obtained, a preferential tooth shape should be selected
("adult", "youth", "lepto", "athlet", "pykno" or "asia") or the "Biogeneric reference" design technique should be chosen.

Bridge Biogeneric design technique
In the New dialog box, for "Bridge" restorations, you can select the design
technique "Biogeneric".
You can mark the bridge configuration in the New dialog box as usual.
Then you can enter the preparation margins and base lines from the distal
in the mesial direction as for a bridge framework.
Once the last line has been entered, it is possible to edit all lines.
After determining the direction of insertion, a biogeneric suggestion is calculated.
All of the tools required to modify the suggestion are now available to you.
If you have scanned an antagonist, the occlusion can also be adapted automatically (as for a single anatomical crown).
The design of the crown does not yet have to be definite at this time; it
can be corrected at any time until shortly before the milling preview. For
this purpose, a double-click on an unselected crown is sufficient to enable
its subsequent adaptation.
As soon as you are satisfied with the design of the bridge, you can click
the green "Next" arrow to change to the milling preview, where the freeforming tools "Form", "Drop" and "Shape" are available for the final finer
details.
CAUTION
No connectors between crowns
The user himself is responsible for the coherence of the bridge! Do NOT
place any connectors between the crowns!
When using the "Cut" tool, the cut surface is displayed in the status bar.
This allows you to verify the thickness of the connection surfaces.

Designing abridge framework
Orientation of bridges on the model holder
This chapter is only relevant if you use the scanner in the milling unit.
The positioning of the scan models on the L-shaped model holder influences the correctness of the labeling designating the sides in the 3D software.
If the procedure explained in the following is not observed, the designations on the 3D model will be incorrect, which can lead to faulty restoration
suggestions.
Following the scanning process, the model can be subsequently rotated
on screen with the "Design"/"Insertion axis" menu item (see "Correcting
the orientation of bridges" [ ➙ 140]).

C

C
Mesial –> toward clamping shank A
For single-tooth models, this refers to the mesial side of the tooth to be
restored.
For bridge frameworks, a distinction must be made between several different cases:
● If a bridge only contains teeth from a single quadrant, the mesial side
of the bridge is unambiguous.
● If a bridge contains teeth from 2 quadrants, the "most distal" tooth (incl. partially edentulous) is moved in a "distal" direction (i.e. away from
the clamping shank). In this way, buccal and lingual designate the
correct side on the 3D model.
● If a bridge contains the same number of teeth from 2 quadrants, the
1st (3rd) quadrant is positioned in a mesial direction (i.e. towards the
clamping shank). In this way, buccal and lingual designate the correct
side on the 3D model.

Area coverage for preparation and occlusion impressions
● The preparation and occlusion impressions should cover an almost
equally large area.
Terminal situations
● Terminal situations are always distally terminal. The image of the
tooth to be restored (prepared tooth) must never be acquired so that
it lies on the mesial image border. Part of the neighboring tooth is always to be expected at the mesial end.
Scanning axis and position of model for inEos
● For inEos:
Make sure that the scanning axis and the position of the model are
not changed between the between the occlusal and the preparation
impressions. The image quadrants must be captured so that they are

Error messages
Operator's manual
This type of error typically occurs whenever the construction lines are unsuitable. It may, however, also be caused by a program error.
When you click Yes, a dialog box with further details and hints opens.
The error description, i.e. the ID, is used by the hotline or development
team to analyze and eliminate the problem.
In most cases, you can continue to work with the restoration data after
acknowledging the error. However, just to make sure, you can create a
copy and work with this copy. In this way, you can always recur to the original optical impression in case further problems occur.
11.3.4
This error may occur if the restoration is to be milled. In this case, the restoration to be milled cannot be calculated with the available construction
lines.
As before, you can usually continue to work with the restoration data after
acknowledging this error message. For reasons of safety, you may of
course work on a copy.
Check and correct all construction lines, if necessary.

✔ CEREC Connect has been started.
✔ "Order Data" is selected in the "Accept/Reject Order" tab.
1. Click on the link of the digital impression.
ª The inLab 3D software automatically starts with the step "Check
order". Here you can view the dentist's impressions of the preparation, the partial bite and the antagonist.
2. Now decide whether there is adequate data available, whether the
bite is correct, etc. in order to design the restoration.
ª If the dentist has marked the preparation margin, it appears as a
magenta-colored line. If he has not, there no line shown.
3. Click on the "Next" icon to return to the "Accept/Reject Order" tab in
the CEREC Connect Portal, where you can now accept or reject the
order.
ª The data record remains open in the background, thus enabling
you to start designing the restoration as soon as you close the
CEREC Connect Portal.
4. Select a patient from the list or create a new patient by clicking the
"New" button.
5. In the next step ("Connect order change"), you confirm the restoration
type, design technique and tooth number by clicking "OK".
6. If necessary, you also can make changes in the presettings and then
confirm them with "OK".

Introduction
Introduction to quadrant restoration
CEREC Connect software can be used to produce both single-tooth and
multiple restorations (quadrants). For these cases, a specific workflow
must be observed, which is described in the following.
The following example shows a typical quadrant case. A dentist has
made an optical impression of an inlay and two crowns (anterior and posterior tooth crowns) on one jaw, and sent it to your laboratory.
1. Open the inLab 3D software.
