Alignment Interface
Alinhamento Geral
O alinhamento é uma etapa intermediária que muitas vezes passa despercebido, pois é quase sempre automático. Na verdade, quando o alinhamento automático for bem-sucedido, o usuário verá apenas uma janela de verificação de alinhamento.
A janela de verificação de alinhamento mostra todos os itens alinhados em cores diferentes e uma barra de ferramentas específicaː
- 40px Anterior
- volta para a etapa anterior. Ícone não ativo durante a primeira etapa de escaneamento.
- 40px Fixar Alinhamento
- mostra uma lista dos itens alinhados para permitir ao usuário consertar um deles, caso ele seja incorreto.
- 40px Avançar
- Avança uma etapa no projeto. Esta opção não está disponível até que todos os itens tenham sido identificados e separados
Ao clicar no botão x25px, a lista de itens alinhados é mostrada.
Ao clicar em um dos itens alinhados, o painel de alinhamento manual se abre para permitir ao usuário corrigir o alinhamento realizado automaticamente.
Na etapa de alinhamento manual é mostrado, no centro da janela, o elemento fixo ou de referência ao qual o item detalhado será alinhado; no canto superior direito, o item flutuante ou em movimento que será combinado com a referência; uma barra de ferramentas específica.
Exit- Exits the Option section.
Best Fit- Fixes the alignment between the two images. This action is usually automatic.
View Floating- Shows or hides the image of the floating/ moving item.
Accept- Accepts the changes and closes the option section.
To perform the alignment, put the two images (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.
Accept or cancel the changes to continue with the project.
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 instead. 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 ScanWay, 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; a teeth graphic showing the elements that need to be aligned; a specific toolbar.
The toolbar offers this options:
Previous- Goes back to the previous step. Icon not active during the first scanning step.
Change implant library - Allows to change implant library, for instance if in one case have been used different connections.
Show model - Shows or hides the reference model underneath the markers.
Reset- Restarts the alignment from the beginning.
Next- Goes forward one step in the project. This option is not available 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 position ,mark one point as suggested in the library image. Repeat for all the acquired elements, not necessarily following any order.
