Version 3.0.0 Release Notes
Version 1.0
August 22nd, 2011
New features
1. Automatic margin detection
The margin on ditched dies can now be detected automatically without any user intervention. The use of this tool is limited to scans where the margin is visible as an outer edge all around. As usual, the detection can be modified as needed by the user.
2. Automatic insertion axis
An ideal insertion axis can now be computed either for single element or bridges. The software will try to
minimize the undercuts all around to propose the best axis. Nevertheless the user can still modify the detection, to fine tune it to the particular needs of the case.
3. Unattended Full Automatic MultiDie Session
Using the “Automatic margin detection”, “Automatic insertion axis” and default parameters from the material database on properly ditched dies, the MultiDie software can execute scan and design operation completely unattended. The user can validate the design or modify it accordingly. Also, for those not using the traceability tools in DWOS, a new “Auto-assign to plate” function has been added to automatically place the items on the MultiDie plate instead of manually picking them one by one. To speed up the process a new choice of scan resolution has been added “High” or “Medium” on 3Series and 5Series (“Low” will be accessible only on the 7Series),“High” being the classic resolution used previously and “Medium” gives a 30% speed gain overall.
4. Upper & Lower simultaneous scan and design
The software now supports the creation of clinical cases containing both upper and lower preparations. This in conjunction with the virtual articulator gives a powerful tool for achieving complex cases. However on 32 bits systems, the memory limitation can be an issue when scanning so we recommend taking that into consideration before starting such a case.
5. Virtual ArticulatorA virtual articulator has been included in the software to facilitate occlusion design on complex cases. The model loaded by default is based on the SAM® SE Special Edition Articulator and is fully customizable. Articulators can be calibrated in scanners to accurately position the model in the virtual world. The virtual articulator module in the design station allows creating dynamic occlusion surfaces based on stored explorations to deliver superior prosthesis designs.
6. New User Interface
A new user interface is delivered by default with the 3.0 release using a darker theme to reduce eye fatigue when spending long hours using the software. Some interfaces also have been reworked, especially the “Order Receiving” application. No need to right-click or push a button to enter editing mode, everything element is active and uses default selection from the user preferences, select material and restoration type, click on the element and route the order, as simple as that.
7. Abutment with Waxing
A new type of restoration is now available in the software, where the user can merge the scan of any kind of Wax-Up and the scan of implant locators. By having the precise position of the implant, the interface file from the implant kit database and the surface of the Wax-Up scan, the user can merge it altogether to create a wide variety of implant-born restorations (bars, Prettau type bridges, etc).
8. Partial Framework Integration
The partial framework application has been completely integrated into standard DWOS deployment and database, and exists as a CAD station in the generic client. Attention has been focused also on providing a new scanning workflow where the user can identify the teeth where the clasp will lay to have a near perfect scan of the clinical case. A partial framework order will follow the classic steps of “Order Creation”, “Scan” and “Design” to the exception that there is no “CAD engine” step needed but go straight to CAD design. Several improvements have been also made to the algorithm to ensure stability and freedom of design.
9. Improved Impression Scanning results
The meshing of impression scans has been greatly improved to take into account the specific requirements of building a positive from a negative shape, to show better details on edges and groove, reducing the occurrence of “inverted surface”.
10. Improved 3 points repositioning tool
A new tool to reposition two meshes together has been added in the scan preparation menu. This tool gives parallel separate views of both meshes and a combined view of the result. The user can click the common points in whichever view and will see the result in real time. Once the pre-positioning has been done, he can fine tune the result by clicking on the “Precise Repositioning" button. This tool is used mainly used for finding the implant position by repositioning theoretical file of implant locator in a scan, but can be also be used to correct the automatic repositioning of a preparation scanned on the MultiDie plate in the arch scan for a bridge.
11. Attachments
A new type library has been added to the database, attachments. Attachments can be stored in DWOS using STL files for the male (required) and the female (optional). After defining the attachment connection surface in the library, the user can import it in a design and merge it on the restoration of its choice. All attachments in a single design can be parallelized using a shared axis. In the future DWOS will package some standard attachment from the leading manufacturers (pending their agreement).
12. Ease-of-use of design tools
Design tools have been redesigned to improve software efficiency. It is now possible to easily switch between designers (virtual waxing, global transforms and clinical handles) and also between restorations by simply clicking on the one to activate. No need to validate after each single design, just flow to the next one, or activate all at once.
13. 64 bits support
DWOS software can now run of 64 bits operating systems. This will enable Java to take advantage fully of the available memory on the system without any restriction (as opposed to a 1.3 Gb limit on 32 bits systems),and improve the overall performance of computation heavy algorithms.
14. 3D Connexion support
Support of devices from the manufacturer 3D Connexion has been implemented so that any 3D view in the software can be manipulated using an additional controller like the “Space Navigator”.
15. DHS Enhancements
Share users information. Share kit objects : Implants, Anatomies, Attachments. Share Material information.
Known Issues
• Scanning without an articulator after it has been calibrated: Using a calibrated virtual articulator in a
CAD session with a case not scanned with this articulator will result in bad original positioning within
this articulator.
• Dual arch Partial Modeling Surveyor: With a dual arch model, it is only possible to do parellization once.
Both upper and lower arch will have the same parellization.
