The DATRON D5 Dental Mill

Empowering labs to mill titanium implant bars and custom abutments in-house

Before development of the D5 Dental Mill started in Germany, DATRON carefully examined the landscape of dental CAD/CAM technology and identified which voids needed to be filled. The market was already saturated with easy-to-use bench-top units that successfully milled crown-and-bridge restorations in zirconia, wax, and PMMA. Additionally, there were a handful of advanced dental mills touting more robust features, such as automation, additional tool holders, and the ability to mill harder materials like titanium or chrome cobalt. However, these machines still lacked the accuracy and rigidity to manufacture titanium implant bars and custom abutments that meet the extremely high standards set by implant manufacturers.

The goal in designing the DATRON D5 Dental Mill was two-fold: 1) design a highly precise machine to mill difficult materials such as titanium with superior results; 2) make it easy to use for dental technicians without CNC machining experience. As a result, the D5 is the first industrial-grade dental milling machine in the world to be controlled by the touch of an Apple iPad, and it is quickly earning a name as the standard for producing implant parts with superior fit and finish. This machine gives laboratories and milling centers the ability to bring titanium-implant production in-house, while maintaining the quality and precision that these complex geometries demand. Lowering the bar was not an option, so the D5 does not make any sacrifices.

To do this, DATRON realized it would have to develop a machine from the ground up specifically for dental milling applications, or in this case, from the “puck out." Envisioning a standard disc of 98.5-mm grade-5 titanium as the very heart of the machine, DATRON engineers based every aspect of their design on efficiently and accurately holding, moving, and milling that piece of material.

DATRON D5 features that ensure implant milling success:

Industrial rotary axis: The rotational movements of the fourth and fifth axes converge in the middle of the blank and are each supported at both ends. This minimizes positional error and increases the structure’s rigidity.

Minimum-quantity coolant system: The minimum-quantity coolant system is not only easier to service and maintain than traditional flood coolant, but it also offers extended tool life for milling with small-diameter tools at high spindle speeds.

High-speed spindle with HSK tool holders: The water-cooled 1.8-kW spindle is the only one in the dental industry that features HSK tool holders to reduce runout (vibrations) at the tip of the tool, increasing accuracy of the final milled part and greatly contributing to significantly longer tool life—as much as 10 times better than traditional dental milling machines.

Linear scales for ± 5-μm accuracy and 2-μm repeatability: Optional linear scales on the D5 LS compensate for thermal changes on the fly throughout the milling process and increase the machine’s accuracy to an industry-leading 5 microns across the entire work area.
