The alignment is an intermediate step that often goes unnoticed since it is almost always automatic. InfactIn fact, 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 until 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:11-->
;{{List button|cancel.png}} Exit : Exits the Option Options section.
;{{List button|bestFitAction.png}} Best Fit: Fixes the alignment between the two images. This action is usually automatic.
;{{List button|viewFloatAction.png}} View Floating: Shows or hides the image of the floating/ moving item.
;{{List button|BigpanelAction.jpg}} Big Panel: Shows the floating item in a bigger panel.
;{{List button|Ok.png}} Accept : Accepts the changes and closes the option section.
<!--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 a '''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.
<!--T:20-->
The scan of the implant marker itself is not enough: its resulting data will be used to compute the exact position of the implant interface. In order to carry out this operation, an [[Implant_Library|Implant Library]] is needed .
<!--T:21-->
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.
==Library Selection== <!--T:22-->
<!--T:25-->
The Panel is divided in into 4 Sections:
<!--T:26-->
* A Filter box where it is possible to write part of the name of the needed implant. All the implants that match the name will be showed in the implant list
* An implant list with all the implants available in the current Implant Library
;Type and Sub Type :For Choosing the diameter and type of connection. There can be many of these types, in our libraries , for instance , there are:
* Engaging Connections : the connection can not rotate on the implant, suggested for abutments or single restorations
* Not-Engaging Connections : the connection can rotate on the implant, suggested for bars and bridges
* For Zirconia : connections with specific shapes, suited for zirconia restorations
;Preview :Shows the preview of the STL marker present in the library
;Info : If the library is correctly configured to work with our software, in this section it is possible to have a small overview of the libraries with additional information on the availabe available diameters and implant types.
All our libraries are provided with this feature and, being connected to this wiki, the ''Open in browser'' button opens the wiki on the implant list page.

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-->
The toolbar offers this options:
;{{List button|prevAction.png}} Previous: Goes back to the previous step. Icon not active during the first scanning step.
;{{List button|changeImplantLibAction.png}} Change implant library : Allows to change implant library, for instance , if in one case have been used different connections.
;{{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.
<!--T:34-->
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.
