Delcam’s SEACAM to Show Latest Dental Developments in Brazil
Delcam’s Brazilian reseller SEACAM will demonstrate the latest versions of the DentCAD dental design software and the DentMILL dental machining system at the CIOSP exhibition in Sao Paulo from 31st January to 3rd February. Also on display will be the PartMaker software for the manufacture of dental screws and instruments, plus the Imetric dental scanner.
This event will be part of a growing emphasis on the healthcare industry at SEACAM during 2010. Like Delcam itself, SEACAM will use its many years of experience with CADCAM to help medical companies in Brazil to increase productivity, reduce lead times and cut costs, and so provide a higher-quality service to their patients.
The 2010 version of DentCAD includes a completely new interface, an integrated data management module, an expanded library of standard tooth designs and improved STL file output for rapid prototyping equipment, as well as a number of enhancements to the design options, while the new DentMILL has additional five-axis machining options.
The improved DentCAD interface features a reduced number of toolbars to allow the maximum screen space for design, while the icons have been made bolder and clearer. Even dental technicians with limited experience of computer-aided design will find the software easy to learn and to use.
The new data management module makes it easier to record the details of the patient and dentist, and the restoration and material type etc. It enables a smooth process flow between the scanner used to collect the initial data, DentCAD and DentMILL.
Among the design enhancements is the automatic creation of a prep-line as soon as the restoration design is started in DentCAD. The prep-line is the most critical area of the design as it marks the border between the tooth and the gum, and so determines the accuracy of the fit of the restoration. The automatically-generated line can be edited by the user if required.
To reduce the chances of failure of the restoration in manufacture or, even worse, after fitting, DentCAD now lists any areas where the thickness of teeth fall below a chosen set of minimum parameters. The text description of any problem areas is reinforced by a colour map which highlights all the surfaces that fall below the specified requirements.
The extra five-axis machining options in DentMILL will make it easier to program the manufacture of dental bars, implant bridges and customised abutments. In addition, the previous options for the production of copings, bridges and abutments in ceramics and titanium have been enhanced. In particular, the ability to use multithreading technology has reduced calculation times for users with multi-processor computers.
As well as broadening the range of dental restorations that can be produced, the use of five-axis machining helps to reduce material wastage, minimise hand-finishing operations by removing undercut regions, and give more flexibility when machining difficult parts and materials such as hard-state Zirconia.
PartMaker is Delcam’s dedicated machining software for the programming of turn-mill equipment and Swiss-type lathes. Using PartMaker rather than manual programming helps to reduce set-up times, while the unique synchronisation options keep cycle times to a minimum. The machines are used extensively in the dental and medical industries for the manufacture of items including dental screws, prosthesis and operating equipment.
The Imetric scanner uses state of the art white-light scanning technology for unparalleled measurement accuracy and, therefore, outstanding fit in the finished restoration. The equipment is simple to use and includes many advanced features such as multi-die scanning, which allows the user to start the design process on the first item while the remaining models are still scanning.
