Implant Alignment
Implant Acquisition
When acquiring the data for a project on implants, acquiring the implant itself is really difficult. It's not like a stump or a piece of stone model. The implant connection/interfaces normally are small and metallic.
Moreover the fitting needs to be mechanically perfect, there is close to no margin of error.
To solve this problem the implant connection is not going to be scanned directly, an Implant Marker is going to be used insteads, being it a specific object designed to be scanned that fits exactly over the implant you need.
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 is needed Implant Library.
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 Dental, in order to get better results.
Implant Selection
After the mesh generation, if you select the mesh of an implant marker from the project tree, the Implant Alignment button will appear in the Main Toolbar. You can then click on this button to open the Implant Selection dialog.
This dialog is made by:
- A tooth position selection (the button with three dots ...) that can be used, only in Free Mode to select the tooth position of one implant
- An implant list with all the implants availables in the current implant library
- A Filter box where you can put part of the name of the implant you need and all the implants that match the name will be showed in the implant list
You just need to select the implant you want to use and click the Select Button.
Choosing the right implant from the library need care. Many implant libraries have different versions of every implant connection. For example you can find:
- Engaging Connections : The connection used can not rotate over the implant, for abutments or single restorations
- Not-Engaging Connections : The connection used can rotate over the implant, for bars and bridges
- For Zirconia : Connections with particular shapes, suited for zirconia restorations
If you select the wrong implant you can do again all the procedure to replace the old connection aligned with a new one.
If you start the CAD design with a wrong connection you'll need to redo all the design from the start
Implant Alignment
When you select the implant connection you want to use the software will enter in the Manual Alignment mode.
You'll have to align the marker acquried mesh with the library marker shape. From this data the connection position will be computed
This procedure needs to be done for every implant in the project. The CAD Export will issue a warning if miss one or more implant alignments.

Now that you know how to align an implant acquisition to the implant library you can return to the Main Page or read about Export functions.
