本页将介绍扫描具有4种种植体和硅牙龈部分的1个模型的向导。

要在Exocad中创建此项目，请点击桌面上的DentalDB图标。项目管理器将打开。

填写项目信息、需要设计的修复类型和额外的参数。对于这种项目，请确保您已经选择了'''种植体类型'''和'''分离的牙龈'''。

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-implants.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-implants.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-implants.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：上颚模型==

Since there isn't an opposing model in the defined project, the first required scan is the scan of the upper model, which will be the reference for the positioning of all the other scans. This step is divided into two sub-steps.

===扫描步骤===

将上颚模型放在模型支架上，然后点击'''扫描按钮'''{{Inline button|scanAction.png}}。

'''AT THIS STAGE, ONLY THE STONE MODEL IS REQUIRED. REMEMBER TO TAKE OFF THE MODEL THE GINGIVA, MARKERS, AND ANY OTHER ACCESSORY OBJECT'''

扫描结束后，显示结果。

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

===编辑步骤===

此步骤可以编辑采集的图像；有关此步骤中所有可用选项的详细信息，请访问[[Edit|编辑工具]]页面。

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.

Here below an example of how to trim using the cut base tool and simply double-clicking on the image to remove the unwanted parts.

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2：标记==

This step requires the user to scan the markers or scanbodies that will be used to mark the correct positioning of the geometry and screw channel of the implant in the CAD software. The scan of the markers is divided into different steps.

===定义===

并非模型上的每个种植体都要有一个标记，因为可以以不同的组扫描标记。为了证明这种可能性，需要为此项目进行扫描的4个标记被分为两个扫描组，如下所示：

[[File:scan-groups-implants.png]]

点击{{Inline button|nextAction.png}}访问第一组的扫描步骤。

===第一组===

;扫描：根据创建的扫描组数量，软件将提出一个或多个扫描步骤。

首先，软件要求用户将旋在模型顶部的标记插入扫描仪中，并采集第一组的项目。 提醒：窗口右侧直播视图下将标记要扫描的项目。

将模型与所选标记放在模型支架上，然后单击'''扫描按钮'''{{Inline button | scanAction.png}}。扫描结束后，显示结果。

[[File:markers1323-steps.png]]

点击{{Inline button|nextAction.png}}进入编辑步骤。

;编辑：按照编辑步骤清理或修剪图像。此时，使用矩形选择工具，并在上下文菜单中激活了剪切操作。

[[File:edit-13-23.gif]]

点击{{Inline button|nextAction.png}}进入对齐步骤。

;对齐：所有扫描项目的对齐方式始终是自动的，并在编辑步骤后显示其结果。 要了解有关自动对齐和手动过程的更多信息，请访问我们的[[Align|对齐界面]]页面。

;Marker Identification: When a scan group has more than one item, the user will be asked to separate each marker from the others to correctly identify it. To learn more about the identification of the dies visit the [[Scan|Scan Interface]] page.

[[File: separate-23-13.gif]]

点击{{Inline button|nextAction.png}}继续。

===第二组===

;扫描：因为在项目中，标记已被分为两组，这是标记采集步骤的最后一次扫描。

如前所述，软件会在窗口右侧直播视图下显示提醒信息，并将一起扫描的项目标记在一起。

将模型与所选标记放在模型支架上，然后单击'''扫描按钮'''{{Inline button | scanAction.png}}。扫描结束后，显示结果。

[[File:markers1525-steps.png]]

点击{{Inline button|nextAction.png}}进入编辑步骤。

;编辑：该图像已经用多边形选择工具编辑；剪切操作已在上下文菜单中激活。

[[File:edit-15-25.gif]]

点击{{Inline button|nextAction.png}}进入对齐步骤。

;Alignment: The alignment for all scanned items is always automatic and it shows its results after the editing step. To learn more about the automatic alignment and the manual procedure visit our [[Align|Alignment Interface]] page.

;Marker Identification: When a scan group has more than one item, the user will be asked to separate each marker from the others to correctly identify it. To learn more about the identification of the dies visit the [[Scan|Scan Interface]] page.

[[File: separate-25-15.gif]]

点击{{Inline button|nextAction.png}}继续。

==步骤3：牙龈==

如果在项目中指定了存在可以与模型分离的硅牙龈，软件将要求用户在参考模型的顶部进行扫描。 此步骤也在不同阶段执行。

===扫描步骤===

将上颚模型与牙龈放在模型支架上，然后单击'''扫描按钮'''{{Inline button | scanAction.png}}。 扫描完成后，将显示结果。

[[File:gingiva-steps.png]]

点击{{Inline button|nextAction.png}}继续。

===编辑步骤===

This item has been trimmed using the rectangular selection tool; the selected part has been deleted by pushing the DELETE (DEL) button on the keyboard.

[[File:Edit-ginigva.gif]]

点击{{Inline button|nextAction.png}}继续。

===自动对齐===

对于其他项目，牙龈的图像自动对准其参考（上颚模型）。然后将自动删除与参考匹配的模型部分，以仅保留网格格式的实际牙龈部分。

点击{{Inline button|nextAction.png}}继续。

==步骤4：健康齿和桥体==

At this stage, the project has been scanned, unless the user wants to rescan the healthy and pontics. In this case, since there are no healthy teeth there is no need to rescan.

点击{{Inline button|nextAction.png}}继续。 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的图像。 按照前面的说明进行编辑步骤。

==步骤5：标记对齐==

To serve their purpose, the markers need to be aligned to a '''implant library''': a virtual, geometric, accurate representation of the scanbody that has been screwed to the stone analog to mark its position. The alingment to the library can be performed either in the scanning software or in Exocad. Since the market of libraries and scanbodies is so diverse, it is possible that some libraries will not work in our system.

以下是我们演示病历所选择的库：

[[File:select-library.gif]]

之后，用户马上被要求将标记的STL与扫描的项目对齐：

[[File:align_markers.gif]]

To learn more about how to select a library and align the scanbodies to it, visit the section '''Marker alignment''' of the page [[Align|Alignment Interface]].

==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.
