本页将进一步介绍扫描2个咬合模型的向导，该模型具有3个代型（2个上颚和1个下颚）。

==Project definition starting from Exocad==
 
To create this project in Exocad, click on the DentalDB icon on your desktop. The project manager will open.

填写项目信息、需要设计的修复类型和额外的参数。对于这样的项目，请确保'''扫描模式'''设置为'''咬合的两个石膏模型'''。

有关如何在Exocad中创建项目的更多信息，请访问[http://wiki.exocad.com/wiki/index.php?title=DentalDB_Module Exocad Wiki?]上的特定页面！

以下是我们演示项目的项目定义：

[[File:prj_definition_exo.gif]]

一旦定义了项目，只需在“操作”部分中单击 '''OPT'''，即可启动扫描软件。

[[File:exo_to_scanway.gif]]

扫描软件首先显示的是在Exocad中创建的项目，如果项目定义正确，请点击“接受”按钮{{Inline button|ok.png}}。

==从ScanWay开始的项目定义==

所有的项目都可以在扫描软件中进行定义，不管以后使用哪个CAD进行设计。

双击桌面上的ScanWay图标启动扫描软件。[[Splash|欢迎页面]]将打开；要创建项目，请点击第一个图标。

有关如何定义项目的详细信息，请访问特定页面：[[NewPrj|创建新项目]]。

这是我们的演示项目的定义：

[[File:prj_definition_cemented.gif]]

所描述的项目定义都会指向同一个向导，现在将逐步遵循该向导。

==步骤1：咬合架扫描==

任何已设置为具有双颚的项目的第一步是扫描咬合架。

'''咬合架扫描并不一定意味着要对咬合架进行扫描；所需的扫描是使用特定支撑件上的咬合架，或将两个咬合模型放在模型支架上采集咬合。'''

If the user needs to scan an articulator, we suggest to tilt it backward, to be able to get as much information as possible. This is just a suggestion as not all articulators can be tilted.

[[File:articulator_positions.png]]

In the live view of the scanning interface, you can actually see that if the articulator is standing straight it will be difficult to acquire the occlusion properly.

[[File:live_arti_posizioni.png]]

另一方面，如前所述，如有需要，还可以扫描使用橡胶条或蜡贴在一起保持在正常模型支架上的两个模型。

[[File: arti-modelli.png]]

一旦将对象放置在扫描仪中（咬合架或模型互相交叠放置），可以用'''扫描按钮'''{{Inline button | scanAction.png}} 启动扫描。扫描结束后，显示结果。

[[File: articulator-steps.png]]

如需有关其他可用功能的更多信息，请查看[[Scan|扫描界面]]页面。

单击{{Inline button|nextAction.png}}以访问向导的第二步。

==步骤2：下颚模型==

任何被设定为具有双颚的项目的第二步是下颚模型扫描。除了咬合架相关步骤，所有步骤都包括两个子步骤：实际的扫描和采集图像的编辑。

===扫描步骤===

将下颚模型放在模型支架上，然后单击'''扫描按钮'''{{Inline button|scanAction.png}}。扫描结束后，显示结果。

[[File:lower-model-steps.png]]

This scan has been performed with the Reference Rim. Every time the user launches a scan for models, dies or markers, if the software recognizes that the reference rim has not been used the following message shows.

The user can, therefore, decide whether to cancel the scan, put the reference rim on the model holder and start a new scan or to scan without using the reference rim. For information on the reference rim visit the [[Accessories|Accessories]] page.

点击{{Inline button | nextAction.png}}进入下颚模型步骤的第二部分。

===编辑步骤===

This step allows to edit the acquired image; for detailed information on all the available options in this step visit the [[Edit|Edit Tools]] page.

The image at this step can be both edited or trimmed. At this stage, it is actually important not to edit too much the image or cutting big chunks of information, since it would make it more difficult for the software to calculate the automatic alignment of the object to its reference.

可以使用选择工具编辑图像。

另一方面，'''切割底座'''工具非常便于修剪。

当您对结果感到满意时，请点击{{Inline button|nextAction.png}}以访问下一个向导步骤。

===步骤3：上颚模型===

上颚模型扫描与下颚模型扫描一样，要求用户进行两个步骤。

===扫描步骤===

将上颚模型放在模型架子上，然后单击'''扫描按钮'''{{Inline button|scanAction.png}}。扫描结束后，显示结果。

[[File:upper-model-steps.png]]

如前所述，如果参考垫没有放置在模型支架上，软件将显示相关信息。

点击{{Inline button|nextAction.png}}以进入上颚模型的编辑步骤。

===编辑步骤===

上颚模型仍然可以按照下颚模型相同的步骤进行编辑。这一次，我们将使用不同的选择工具编辑图像。

[[File:edit-upper.gif]]

当您对结果感到满意时，请点击{{Inline button|nextAction.png}}以访问下一个向导步骤。

==保存并对齐==

按{{Inline button|nextAction.png}}按钮之后，软件将立即保存并尝试自动将已扫描的项目对齐其参考。

[[File:save_and_align.gif]]

To learn more about the automatic alignment and the manual procedure visit our [[Align|Alignment Interface]] page.

==步骤4：代型扫描==

The steps necessary to successfully scan the dies vary depending on the scanning method that the user chooses to apply: the use of the multi-die plate or the custom set-up.

===使用多代型===

This method is applied by default by the software. It implies that the user will put the dies on the multi-die plate in the position shown by the software, which will make each die immediately recognizable and cut the steps of the wizard.

;Definition: As mentioned, the position of the dies in the multi-die plate is pre-established by the software.

The multi-die order is based on the Universal tooth numbering, starting from the last element of the first quadrant and following in a clockwise order. Therefore the die that needs to be placed in the central element will always be the one closest to the last element of the first quadrant.<br /> If there are more than 9 dies, a second definition step will be shown.

点击{{Inline button|nextAction.png}}以进入多代型扫描步骤。

;Scan: The multi-die scan interface is similar to the other steps we just explained, except for the multi-die reference that is kept as a reminder on the right side of the window, under the live view.<br /> To proceed click the '''Scan Button'''{{Inline button|scanAction.png}}. Once the scan is finished the result will be shown.

[[File:multidie-steps.png]]

点击{{Inline button|nextAction.png}}以进入多代型扫描的编辑步骤。

;编辑：编辑步骤提供了我们在之前步骤中看到的相同工具。在本例中，可能需要应用多种工具。

[[File:edit-multidie.gif]]

当您对结果感到满意时，请点击{{Inline button|nextAction.png}}以访问下一个向导步骤。

;Alignment: After being edited the dies get aligned to their references. The result is then shown on the monitor. To learn how to change, fix or redo the alignment check the [[Align|Alignment Interface]] page.

[[File:dies-autoalign.gif]]

===定制设置（无多代型）===

The user can also decide to scan the dies in a custom order, for instance, if he needs to scan the dies on the model base. To access the custom set- up definition, click on the {{Inline button|customSetupAction.png}} icon when the software presents the multi-die definition.

;Definition: The software proposes by default a unique scan group which means that, if not defined otherwise, the software will ask the user to scan all the stumps together. In this case, I have created a second scan group, to divide the scan of the upper dies from the scan of the lower dies. Click {{Inline button|nextAction.png}} to access the scan steps.

;扫描：根据创建的扫描组的数量，软件将提议进行一个或多个扫描步骤。

首先，软件需要用户将代型插入扫描仪中并采集第一组的项。<br />作为提醒，它将窗口右侧的一起扫描的项目标记在直播视图下。

然后它将要求用户插入为第二组选择的项目。由于第二次扫描的是个人代型，所以右边没有提醒。点击{{Inline button | nextAction.png}}继续。

[[File:dies-steps.png]]

;Dies Identification: When a scan group has more than one item, the user will be asked to separate each die from the others to correctly identify it.<br /> This step occurs in between the scanning steps. To learn more about the identification of the dies visit the [[Scan|Scan Interface]] page. Click {{Inline button|nextAction.png}} to continue.

[[File:extract _24_26.gif]]

;编辑：如果扫描组由一个单独的模具组成，则不会有识别步骤。相反，将显示编辑步骤。点击{{Inline button|nextAction.png}}继续。

;Alignment: After being edited or identified the dies get aligned to their references. The result is then shown on the monitor. To learn how to change, fix or redo the alignment check the [[Align|Alignment Interface]] page.

==步骤5：健康齿和桥体==

At this stage, the project has been scanned, unless the user wants to rescan the healthy and pontics. This step is in fact a result of the scan of the scanned reference model, trimmed to exclude the parts that have been scanned individually (in this case, the dies). It sometimes happens that in the first model scan, the contact points on the healthy are not correctly recognized, which would require the user to rescan the model. Otherwise, just click {{Inline button|nextAction.png}} to continue.

[[File:Healty-both.png]]

然后，软件将提出进一步的编辑步骤，以允许用户修改健康齿图像。按照前面的说明进行编辑步骤。

==第6步：网格生成和导出==

At this point, the software immediately starts mesh generation. The meshes can be edited and exported individually or as a unique image. To learn more about mesh editing visit our [[Mesh|Mesh Tools]] page.

单击“导出”按钮{{Inline button|exportToCadAction.png}}导出到CAD。

If the project has been started from Exocad, the CAD will automatically open and the design can be started immediately. Otherwise, the software will ask the user how to export the file.
