Application Description:

Titanium Implant Bar

Project Description

Screw-retained dental implant restorations require extremely high tolerances throughout the machining process to ensure success once the part is placed in the patient’s mouth. The results obtained on a DATRON D5 LS mill will meet or exceed the fit and finish of implant bars that are produced by any of the major implant manufacturers worldwide.

DATRON tools and parameters were used to machine the titanium bar with an accuracy of < 10 microns. Stock roughing uses a 3mm ballnose, as a 2mm and 1mm ballnose finished the bar profile and small pockets. Implant interface machining uses a combination of radius and non-radius 1.5mm endmills, while the screw channel counterbores are roughed using drills that range in size from 1.5-2.5mm, and are finished with long-reach (16mm) 1.5mm endmills.
