Understanding Curves/Surfaces and Types of Dental Prostheses

• Color: Pink
• Type: Curve

Displayed locations:

Cavity vicinity/accurately above margin lines

Application

This item differentiates the internal and external milling in the strategy. It indicates the correct direction in which to cut the internal cavity (the pink arrows and circles) to allow for the acquisition of the intended results in internal cutting.

Optional or required

Required for objects that have a cavity

• Color: Green
• Type: Curve

Displayed locations:

Center part of cylinders that require drilling/center part of screw channels

Application

This item indicates the cylinder used in drilling.

Optional or required

Required for objects that have a screw channel or cylindrical hole

• Color: Blue
• Type: Curve

Displayed location:

Edge of emergence area

Application

Delimits the end of the emergence area (the green area).

Optional or required

Optional

• Color: Green
• Type: Surface

Displayed locations:

Abutment margin line or between the identification section and the emergence profile curve (blue curve)

Application

To obtain high-quality surfaces, apply a different strategy to this area.

Optional or required

Optional

• Color: Red
• Type: Layer

Displayed locations:

Cylinders/screw channel start point and end point (not present in cavities)

Application

The cylinder cap covers the cylinder entrance, preventing the tool from entering the screw channel access hole during rough milling and finish milling.

Optional or required

Required for objects that have a screw channel or hole

• Color: Pink
• Type: Arrow

Displayed locations:

Abutment, hybrid abutment, bur top

Application

Indicates the finish direction for the abutment top cap.

There should be no screw-retained crowns (having anatomical structures) handled in this manner.

Optional or required

Optional but strongly recommended for abutments, hybrid abutments, and burs.

• Color: Purple
• Type: Curve

Displayed locations:

Base of the angled screw channel of various implants or along the screw channel profile

Application

This item indicates the boundaries of drilling and hole finish milling.

When milling using an angled screw channel in DGSHAPE CAM, the cylindrical hole becomes elliptical or oval shaped.

The following photograph shows a top-down view of an angled screw channel whose inner diameter is visible. Because of this unique shape, you must use a new boundary line and profile to perform drilling.

This curve should be visible at the base of the screw channel, but it is sometimes seen along the screw channel (the milling depth is determined by the drilling axis).

For details on how to place this curve, see Drone Cylinder.

Optional or required

Required when there is an angled screw channel

Displayed locations:

All junctions/interfaces on appropriately identified implants

Application

Shows junctions/interfaces on implants to allow for appropriate milling.

Optional or required

Required for abutment and implant objects
