The alignment is an intermediate step that often goes unnoticed since it is almost always automatic. Infact, when the automatic alignment succeedsucceeds, the user will only see an alignment check window.
<!--T:3-->
<!--T:4-->
The alignment check window shows, all the aligned items in different colors and a specific toolbar:
<!--T:5-->
;{{List button|prevAction.png}} Previous: Goes back to the previous step. Icon not active during the first scanning step.
;{{List button|fixAlignAction.png}} Fix Alingment: Shows a list of the aligned aitems items to allow the user to fix one of them, should it be incorrect.;{{List button|nextAction.png}} Next: Goes forward one step in the project. This option is not available untill all the items have been identified an and separated.
<!--T:6-->
<!--T:8-->
By clicking on one of the aligned items, the manual alignment panel opens to allow the user to fix the automatically perfomed performed alignment.
<!--T:9-->
<!--T:12-->
To perform the alignment, put the two images (fiexd fixed and moving) in the same position and mark one point on the same spot of both items. If necessary, due to difficult matches or lack of information, it is possible to place multiple points on the images.

To solve this problem, the implant connection is not directly scanned but an '''Implant Marker or Scan Body''' is used in its steadinstead. A Scan Body is a specific object, designed to be scanned, which fits exactly over the implant.

The alignment to the implant library can be performed in the CAD software. However, using an implant library for Exocad's Platform, the user can perform this operation directly in the scanning software OpticalRevEng DentalScanWay, in order to get better results.

The interface shows all the acquired markers; an image of the STL of the library with a premarked point; e a teeth graphic showing the elements that need to be aligned; a specific toolbar.
<!--T:33-->
;{{List button|showJawAction.png}} Show model : Shows or hides the reference model underneath the markers.
;{{List button|resetAlignAction.png}} Reset: Restarts the alignment from the beginning.
;{{List button|nextAction.png}} Next: Goes forward one step in the project. This option is not available untill until all the items have been aligned.

To align it is simply necessary to move the scanned markers to mimic the position of the library STL shown in the upper right corner of the window. When the marker is in the correct postion position ,mark one point as suggested in the library image. Repeat for all the acquired elements, not necessarily following any order.
