Here is how to scan a Port & Core using colLab software.
The images below show the scan strategy setting dialog.
You can see the ‘Post & Core’ option in the dialog box along with the indicated tooth number. In this case tooth 25.
If the teeth for 11 and 21 are for veneers and 25 is for post & core, tooth 25 should be turned on and the others should be turned off in the ‘Post & Core’ option.
- Scan the maxilla base of the stone model by using flexible multi-die and flexible grip (these are the new accessories) or the Screw jig . Flexible multi-die can be used for all scanning cases even though the scanning strategy is not defined to use it.
Medit flexible grip is perfect for holding objects that have an irregular shape.

Scan the prepped tooth and mandibular base.
- Scan the maxilla impression. In this example we used the flexible multi-die and flexible grip.
When scanning impressions, colLab 2017 captures scan data from many orientations. If needed, use the ‘add scan’ feature to capture any missing data.
- Set the area of the post in the scan data using the circular widget to get the post data only.
You can control the size of the circle using the mouse wheel.
- Once all scanning is complete, check the alignment between the prepped tooth and base.
- Check the alignment along the maxilla base, mandibular base, and occlusion data.
- Align the post data to the prepped tooth data. Use the 3-point alignment method as it will give the best results with Post & Core alignment.
All alignments are complete.
The post area data should be edited before merging the data.
- Remove the area that is not part of the post area because it can influence the quality of the merged data.
You can easily do this using the ‘Crop’ functional, a new feature in colLab v2.0.0.3.
- Data merging is complete, resulting in a complete Post & Core data set.
