By clicking on a tooth ([7] in the Ceramill Database main window), you can select the type of restoration that will be designed for this tooth. The following dialog will appear:

The restoration types

First, select the type of restoration on the left [1]. The following types are available:

Copings

  • Anatomic coping - A coping which is made from the full anatomic shape (using cutback to create space for ceramic). First, the anatomic shape is designed; then, it is shrunk to create the coping. The „Shrinking“ controls the amount of cutback. In other CAD systems, this type of restoration is sometimes referred to as „Clinical coping“.
  • Offset coping - A simple coping with a fixed thickness above the preparation. It is deprecated to use this; „Anatomic coping“ is usually the better choice, as it gives support to the cusps from the framework. Use only if your customer specifically requests this, or if the operator does not have significant dental know-how to design a proper anatomic coping for the respective patient situation.


Full crowns

  • Anatomic crown - A full crown
  • Pressed crown - A two-part restoration, where the framework will be designed as an anatomic coping; additionally, a second part is created, which contains the chewing surface of the restoration – to be milled in wax/PMMA, later to be burned out („overpress“)
  • Provisional crown- Eggshell provisional crown, which assumes the natural shape of a tooth to be prepared on a jaw scan.


Pontics

  • Reduced pontic - A pontic framework – the full anatomic shape is designed first, the framework is created by shrinking the surface (cutback).
  • Anatomic pontic - A full anatomic pontic without cutback
  • Pressed pontic - Two-part restoration („overpress“)
  • Provisional pontic- Eggshell provisional pontic, which assumes the natural shape of a tooth to be extracted in a jaw scan.


Inlays

  • Inlay/Onlay/Veneer – An Inlay, Onlay or Veneer restoration (full anatomic)
  • Offset inlay – A framework for an inlay with a fixed thickness
  • Veneer - A fully anatomical veneer restoration


Primary units

  • Primary telescope – Primary part for a removable structure (telescopic crown)
  • Bar pillar - bar pillar for bar restoration
  • Bar segment - bar segment for bar restoration
  • Attachment - attachment component for a telescope or bar restoration


Waxups

  • Waxup – Replication of a scanned part by digital copy milling
  • Waxup reduced – Creation of a framework from a scan of a full anatomic wax modellation (digital copy milling with cutback).
  • Waxup – Replication of a scanned pontic by digital copy milling


Removable Dentures

  • Prosthetic Tooth - Prosthetic tooth for replacing missing teeth and their gingival section


Residual Dentition

  • Missing tooth – A tooth that is missing and is not to be restored. You need to define this in order to be able to place connectors between teeth that are „normally“ not next to each other. E.g. to create a bridge with teeth 14-16-17, define 15 as „Missing tooth“.
  • Adjacent tooth – A healthy tooth that is to be scanned, but not to be restored in any way
  • Antagonist – Define this in the opposing jaw of your restorations to use an antagonist scan. Note that you also need to define the antagonist scan type (Bite impression scan, or Artex CR – [7] in the main window)
HotkeyVery often, one job contains several restorations of the same type. You don't need to open the above dialog for each separate tooth – just define the details for one tooth, close the dialog, then hold <CTRL> and click other teeth to apply the same settings. Hold <SHIFT> and click to apply the same settings to several teeth at once (similar to marking files in Windows explorer)




Selecting production method

Next, select the production method [2]. Choose between the milling center Ceramill M-center (Outsource) and milling maschines Ceramill Motion/ Mikro, Ceramill Motion 2 (4X), Ceramill Motion 2 (5X) (Inhouse). Depending on the chosen production method and indication , the list of available materials varies.




Material selection

Now, select the material [3]. This will adjust production parameters (including their minimum and maximum values) to match the material's specifications. Note that list of materials available depends on the type of construction [1] and the production method [2]. Furthermore you have to select the desired construction colour [4], if you want to send the order to the M-center.

WarningDo not change the material if you have already finalized the construction, or plan to use a previously saved CAD scene, as the output data will then not take into account the changed material parameters.




Setting further options (implant type, additional scans)

Once you have selected the material, the right part of the dialog gives you the possibility to adjust additional details:

  • „Separate pre-op scan“ [5] (Yes/No): Chose whether you'd like to use a pre-op model scan for this tooth
  • „Separate gingiva scan"[7] (Yes/No): Choose whether you'd like to use an additional scan for the gingiva mask
    • See "Understanding the difference between Pre-op and Waxup feature" to learn more about the "Pre-op scan" feature, and understand in which way it differs from the waxup "digital copy milling".
  • „Implant type“ [6]: Choose whether this is an implant-based reconstruction, and of which type
    • None: Normal preparation or scanned abutment – no implant-specific functionality
    • Abutment & Crown (Custom Abutment): A custom abutment will be designed, in addition to the selected restoration (e.g the coping)
    • Screw Retained: The construction will be screw-mounted on the implant, without using an abutment
    • Note that the later two options require the purchase of the Ceramill M-plant module


Values you changed, so that they differ from the standard setting, are displayed with red background.




Setting numeric parameters, storing dentist-specific default values

Furthermore, numeric parameters can be adjusted. All adjustments to numeric parameters that you make here in the Ceramill Mind Database will become the default values for the selected dentist/material/construction. E.g. if the default value for cement gap is 0.05mm, but one of your clients prefers a higher value you can change the cement gap to 0.08mm. This will become the new default value whenever this combination of construction/material is used for the currently selected dentist in the future. To make this behavior more obvious, a color coding is used for the background of the slider:

  • Red background: You have just changed this parameter and it will become the new default value
  • Yellow background: This value was previously changed and you are now using the stored default value
  • White background: The value displayed is the global default value and not a dentist-specific setting
TipTo adjust parameters for just one construction, without affecting dentist-specific default values, adjust the respective value during the CAD process, and not in the Ceramill Database. To clear all stored default values for a specific dentist, use the „Clear client-specific defaults“ in the Edit dialog (click [2] in the main Database screen to access this dialog)




Closing the dialog

To apply your settings, click „Save“ [9]. To abort without applying your changes, click „Cancel“ [10]. To delete a tooth selection you made erroneously, click „Delete“ [11], then „Save“.
