Glossary
Analog
Replica of the abutment used when creating model impressions. Analogs help replicate the exact position
and orientation of the restoration on the model as in the patient's mouth.
Anatomic
Construction type using an integral polymer cover (of anatomic shape) directly over the preparation, often
as a temporary restoration. Syn.:
full contour crown (not to be confused with FCZ implant crown).
Antagonist
1- Tooth of the opposite jaw directly facing another. 2- Opposing teeth or jaw. As for the bite index,
antagonist jaw information is used to design restorations.
Anteroposterior distance
Front to back distance. On overdenture bars it is the perpendicular distance between the line formed by
the straight line joining the two distal implants and the center of the most anterior implant. This definition is
not applicable for two implants cases.
ASC or Angulated Screw Channel
1) abutment design which enables the screw channel to be angled up to 25 degrees..
2) abutment production type; ASC has 2 production types : ASC Straight and ASC Angulated.
Bite index
Print left by biting on an imprintable material such as wax. This object is scanned and used for
occlusion information and antagonist shape reference when designing restorations.
Co-Design
Shorthand for abutment-coping co-design, a pair
of restoration objects produced in an optimized workflow.
Construction types
Method of building for copings, crowns or bridges. See Cutback, Standard CAD and
Anatomic.
Cutback
Construction type that calculates the coping's outer limits by reduction (cut back) of a crown shape to
account for ceramic thickness. Also named 'offset'. In the case of abutments, the function Cutback from
crown allows to shape the abutment by adjusting to the shape of the crown.
Emergence profile
Aspect of a restoration (or tooth) with respect to the immediate soft tissues. The section of an object's
emergence profile where it meets soft tissue is sometimes called the margin line.
FCZ implant crown
One-unit permanent
restoration which consists of a full contour (a complete anatomical shape) crown directly screwed on an implant.
The material used is translucent zirconia. FCZ implant crowns can be designed from the NobelProcera
Abutment module, using previously scanned wax-ups.
(Sometimes called FCZ Implant Crown.)
Individual scan
Scanning of a specific object resulting in an independent mesh. Mesh independence means that the object
can be scanned with a different strategy and viewed, designed or edited independently of the other objects.
Margin line
1- (Crowns and copings): limit of a restoration closest to the preparation or gingival soft tissues. 2-
(Abutments): a) outward limit of the shoulder of an abutment, where it is closest to the surrounding soft tissues;
b) upper limit of the emergence profile.
Mesh, sub-mesh
Network of triangles obtained by scanning an object : once textured and rendered, it shows a 3D image of
the scanned object. The 3D view (or scan view) of an object contains at least one mesh. Sub-meshes are individual
scans of objects appearing on the main mesh.
Preparation line
Limit, on the preparation, marking the closest point to the margin line of the restoration.
Segment
Noun. Individual sub-mesh, obtained with the segmentation tool. This sub-mesh is superimposed upon the
original solid model mesh.
Segment
Verb. 1- (Software): divide an individual mesh (typically a full jaw) into individual sub-meshes, so each
component can be processed individually. See segmentation.
2- (Dental model): to saw the jaw model to isolate
the teeth.
Segmentation
Software : separation process that selects a region of a base individual mesh (typically a full jaw),
copies it, and adds it as an individual sub-mesh, so it may be processed individually. The Situation builder
contains the segmentation tool.
Solid model
The solid model is a generic scan model type taking a full jaw solid model as one individual scan
object digitized in one operation (2G). Solid model scan type variations are:
- Solid model ((one individual scan of jaw) : This type is used to produce situations usable with NobelClinician® planning tools.
- Solid with
preparations (one individual scan of jaw and individual scans of preparations). This type has the flexibility to
allow scan strategies for specific objects so design can be more efficient. Segmentation is used afterward for
defining soft tissues and other objects.
Spread objects
This is the default 2G workflow type. Used with segmented models ; it performs a
reference scan of all objects as they are on the model, then a scan of these objects removed from the model and
"spread" in a container. It is a shorter variant of the standard (multistep) method which does not use the
container. The spread objects type also uses different processing sequences for some objects.
Standard
Scan model type. All objects already supported by 1G are Standard. They are often gypsum models with sawn
off detachable units.
Standard CAD
Construction type building copings and crowns by successive additions of material layers.
Translucent zirconia
Restoration material (zirconia based compound),
characterized by its high aesthetic qualities. It is used for FCZ implant crowns.
Unsegmented
Full, solid, as one individual object. The full jaw solid scan creates an individual mesh on the jaw,
which is by nature unsegmented.
Workflow type
The workflow is the succession of steps needed to accomplish the scanning task. There are 2 types ;
Multi-step (legacy 1G) and Spread objects for the 2G. See also Spread objects.
