Defining jobs for individual teeth
From exocad documentation
By clicking on a tooth in the DentalDB 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 . The following types are available (the list may vary depending on your speciconfiguration and the add-on modules you have purchased):
- Crowns and Copings
- Anatomic crown - A full contour crown.
- Coping - A coping derived 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.
- 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").
- 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.
- Provisional crown - an eggshell temporary that is designed preoperatively, using scans of non-prepared teeth.
- Preform crown - A special process to use non-standard milling blanks to provide quick milling times for single crowns.
- Please see Screw Retained Bridge Design: How to deal with non-ideal implant placement for important considerations when setting up cases for screw retained bridges
- Anatomic pontic - A full contour pontic. By default, pontics are connected to adjacent restorations of the same material.
- Reduced pontic - A pontic derived from the full anatomic shape, using cutback to create space for ceramic.
- Pressed pontic - A two-piece pontic consisting of a framework and full contour over-press part.
- Inlays, Onlays, and Veneers
- Inlay – an Inlay or Onlay with full anatomy.
- Offset inlay – a framework for an inlay with a fixed thickness.
- Veneer – a Veneer restoration over a prepped tooth(full anatomic).
- Primary Units
- Telescope – primary part for a removable structure (telescopic crown).
- Bar Pillar – the portion of a bar that connects to the implant.
- Bar Segment – the portion of a bar that provides connection between the pillars.
- Attachment – an extra-coronal attachment.
- Waxup – replication of a scanned part by digital copy milling.
- Digital Copy Milling
- Waxup – a full contour crown created from a full anatomic wax model over a prep (digital copy milling).
- Waxup reduced – a framework full derived from an anatomic wax model a with cutback for porcelain.
- Waxup pontic – a full contour from anatomic waxup over a missing or extracted tooth.
- For Waxup and Waxup reduced, select only the teeth with preparations.
- See section "Understanding the difference between Pre-op and Waxup feature" to learn more about the waxup feature and to understand in which way it differs from "pre-op scan" usage.
- See section "Input data requirements for Waxup feature" for more info on what the specific input data requirements are for the "waxup" feature.
- Bite Splint - a device to expand or correct bites, can be used for custom night-guards and sports-guards.
- Bite Splint - missing tooth - to be used with bite splints, denotes a missing tooth that should be covered with bite splint material.
- Denture - a full denture, for fully edentulous cases using standard tooth libraries.
- Partial Denture - used to define a partial denture framework case.
- 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".
- Healthy 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 scan of two stone models –  in the main window).
Selecting production method
Next, select the production method . Typically, you can chose between 3/4-axis milling or 5-axis milling/laser melting. The main difference is that for 3/4 axis milling, a unique insertion axis is enforced for all elements of a bridge. The exact descriptions in the drop-down box  may vary depending on your configuration; e.g. the options may allow you to chose between inhouse production and outsourced production via a milling center. In some configurations, the selection box  may be absent altogether.
Now, select the Material . 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  and the production method .
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  (Yes/No): Chose whether you'd like to use a pre-op model scan for this tooth.
- 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 : Chose whether this is an implant-based reconstruction, and of which type.
- None: Normal preparation or scanned abutment – no implant-specific functionality.
- 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 latter two options require the purchase of the implant module.
- Separate gingiva scan  (Yes/No): Choose whether you'd like to use an additional scan for the gingiva mask.
Values you changed, so that they differ from the standard setting, are displayed with light blue 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 DentalDB module will become the default values for the selected client/dentist when using this particular material/construction. E.g. if the default value for cement gap is 0.05mm, but one of your clients prefers a more loose fit, adjust it to a higher value like 0.08mm, and this will become the new default value whenever this combination of construction/material is used for the currently selected client/dentist in the future. To make this behavior more obvious, a color coding is used for the background of the slider:
- Red background (as shown in the screenshot above): 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.
Closing the dialog
To apply your settings, click "Save" . To abort without applying your changes, click "Cancel" . To delete a tooth selection you made erroneously, click "Delete" , then "Save".
