Technical Update: Improved BruxZir Esthetics Thru Ultrasonic Cleaning
With the ever-increasing demand for BruxZir Solid Zirconia,
Glidewell Laboratories has continued to devise, test, and implement new
processes intended to improve both the quality of these crown &
bridge restorations and the efficiency with which they are produced.
Often, an innovation in one area provides enhanced results in the other.
One such innovation is the new process by which Glidewell technicians
clean milled BruxZir restorations and prepare them for coloring.

The new method involves the use of an ultrasonic bath to
clean the milled block, which is faster, cleaner, and more effective
than brushing each crown by hand. Crowns are then cut from the block,
grouped by their designated shade, and bathed again, helping to remove
all of the fine particles from the crown surface. The shade-grouped
crowns are then placed in sintering trays and dried — first in a
microwave and then beneath a heat lamp. Once dried, the crowns are
submerged in the proper coloring solution and colored under vacuum,
after which they are dried again before being sintered.
