Allineamento Generale

L'allineamento è un passaggio intermedio che spesso passa inosservato poiché è quasi sempre automatico. Infatti, quando l'allineamento automatico va a buon fine, l'utente vedrà solamente una finestra di controllo dell'allineamento.

La finestra di controllo dell'allineamento mostra tutti gli elementi allineati in colori differenti, ed una specifica barra degli strumenti:

PrevAction.png Precedente
Torna al passaggio precedente. Icona non attiva durante la prima scansione.
FixAlignAction.png Correggere Allineamento
Mostra una lista degli elementi allineati per permettere all'utente di correggerli nel caso non siano corretti.
NextAction.png Successivo
Prosegue di un passaggio nel progetto. Questa opzione non è disponibile fino a che tutti gli elementi non siano stati identificati e separati.

Facendo click sul bottone FixAlignAction.png viene mostrata la lista degli elementi allineati.

Facendo click su uno degli elementi allineati, si apre il pannello dell'allineamento manuale per permettere all'utente di correggere l'allineamento avvenuto automaticamente.

In the manual alignment step are shown, in the center of the window, the fixed or reference element to which the detailed item will be aligned; in the upper right corner, the floating or moving item that will be matched with the reference; a specific toolbar.

Cancel.png Exit
Exits the Option section.
BestFitAction.png Best Fit
Fixes the alignment between the two images. This action is usually automatic.
ViewFloatAction.png View Floating
Shows or hides the image of the floating/ moving item.
Ok.png Accept
Accepts the changes and closes the option section.

To perform the alignment, put the two images (fiexd 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.

Implant Markers

When acquiring the data for a project on implants, acquiring the implant itself is problematic. It's not like a stump or a piece of stone model. The implant connections/interfaces are normally small and metallic.

Moreover, the fitting has to be mechanically perfect, with no margin of error.

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

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 .

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.

Library Selection

The implant library selection is automatically shown when all the items of the project have been acquired.

The Panel is divided in 4 Sections:

Library
For choosing the general connection and implant family, contains:
  • 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 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.


To accept the implant selection click on Select, otherwise Cancel.

If the CAD design is launched using a wrong connection it will be necessary to restart all the design from the beginning

Marker Alignment

Once the library has been selected, the wizard shows the marker alignment step.

The interface shows all the acquired markers; an image of the STL of the library with a premarked point; e teeth graphic showing the elements that need to be aligned; a specific toolbar.

The toolbar offers this options:

PrevAction.png Previous
Goes back to the previous step. Icon not active during the first scanning step.
ChangeImplantLibAction.png Change implant library 
Allows to change implant library, for instance if in one case have been used different connections.
ShowJawAction.png Show model 
Shows or hides the reference model underneath the markers.
ResetAlignAction.png Reset
Restarts the alignment from the beginning.
NextAction.png Next
Goes forward one step in the project. This option is not available untill 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 ,mark one point as suggested in the library image. Repeat for all the acquired elements, not necessarily following any order.
