A few months ago a new zirconia from Germany came our way for testing. It claimed to be a higher grade of 1400 MPa purity with more translucency and improved esthetics. Sound too good to be true? We thought so, however, after a few months of testing, we became believers.
Doceram Medical provided a couple of our labs with various samples of Nacera® zirconia, including Pearl 1 (white), and various value shades capable of reproducing 16 vita classic shades. After making the necessary adjustments to sintering and glazing times and temperatures, the results were in, all exceptionally positive. Nacera® zirconia was kinder to milling burs (lasted up to 15% longer), milled more precisely and smoothly, had less shrinkage variations (each lot/batch has its own shrinkage factor), and was more translucent than other high strength zirconia.
OPT-In member, Dennis King, CDT, has used the full line of Nacera® zirconia, including the multi shade pucks that come in A, B, C, and D shades. He has successfully provided several large full mouth cases of full contour Nacera® restorations that included anteriors, one case for a dentist’s wife. Dennis noticed that Nacera® mills far easier than e.max® and other zirconia, and that his burs have been lasting longer. He also stated that fit is consistently better due to more predictable shrinkage and smoother milling. With his successes fully documented, other OPT-In lab members have also commented positively on the same points.

In a month of testing several different pucks and ceramMotion® (Dentaurum), Roberto noticed more translucency without sacrificing higher strength, better margins with less effort, and predictably better esthetics when compared to competing products. Of particular note, single-step stain & glaze ceraMotion®, distributed by Nacera US, not only improved esthetics, it saved time by requiring only a single stain & glaze bake.
Doceram Medical is establishing the Nacera® brand through a new US subsidiary, Nacera US. OPT-In members are excited about working with Nacera US through a special pricing program, exclusive for OPT-In members. Additionally, the Dental Lab Group, in Staten Island, will provide special Nacera® outsource pricing [only] for those members without milling machines, as well as for custom milled titanium abutments.
Nacera US will be at booth L-22, Lab Day, Chicago, and provide continuous seminars in a private suite. Guests at the suite will enjoy food and beverages, and be able to test stain & glaze the new ceramMotion® on samples of Nacera® zirconia. Roberto Rossi, and others, will be guest lecturers and guiding hands-on experiences. Nacera US has also promised important announcements in February, including the launching of their new website.
