Sitemap Abutment materials. Zirconia, titanium and gold-shaded titanium. Atlantis™ abutments are available in zirconia, titanium or gold-shaded titanium (Atlantis GoldHue™). Each abutment is precision-machined from a solid blank of medical grade titanium alloy or zirconia. Atlantis™ abutment in zirconia. The Atlantis™ abutment in zirconia is perfect for challenging cases in the esthetic zone and is strong enough to be used for all positions in the mouth. The Atlantis™ abutment in zirconia is made of Y-TZP yttria-stabilized tetragonal zirconia polycrystals. It offers unparallelled strength and durability and is one of the few all-zirconia-engineered abutments currently on the market. The benefits of zirconia are the natural, tooth-like colour, the excellent biocompatibility and the reduced plaque build-up compared to titanium. Atlantis™ abutment in titanium The Atlantis™ abutment in titanium is suitable for all positions in the mouth. The Atlantis™ abutments are among the very first CAD/CAM titanium abutments to be anatomically designed and produced for each specific patient and indication. The excellent design means that there is no need for hand-grinding by a technician or a clinician. The abutments are milled from titanium alloy blanks. Atlantis GoldHue™ abutment. The Atlantis GoldHue™ abutment is suitable for all positions in the mouth. It has the same features and benefits as the Atlantis™ abutment in titanium, but in addition it has a thin coating of titanium nitride, which gives it a warm gold-shaded color. This is an advantage in esthetically challenging cases with thin soft tissue or when using an all-ceramic crown. Atlantis™ abutments are not only individually designed and produced for the specific space they will fit, but also in relation to each other for an optimal result when creating full jaw or multiple unit restorations.
