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.


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).


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.


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.


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.


Noun. Individual sub-mesh, obtained with the segmentation tool. This sub-mesh is superimposed upon the original solid model mesh.


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.


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.


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.


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.
