Hygienic design is critical to long term success of full arch prosthetics. CHROME Emerge is a solution to meet a particular philosophy of concave ridge shape that accepts a bullet, convex shaped prosthetic. Emerge is CHROME business-as-usual, with an extra guide for directing the bur in a particular angle to remove a trough along the flattened ridge. This technique over the years has involved just using a bur to adjust the tissue post surgery, but with CHROME, the tissue can be indirectly contoured by adjusting the bone during surgery. Hygiene, emergence, and esthetics are all benefits of Emerge.
