Patient Specific Custom Milled Abutments

We have chosen Atlantis™ abutments for our patient specific, custom milled abutments. They are available for all major implant systems, including Astra Tech, Biomet 3i, Nobel Biocare, and Straumann, and are digitally designed with the ideal buccal-lingual, mesial-distal, and cervical-incisal dimensions based on the surrounding dentition and opposing occlusion. Atlantis VAD™ (Virtual Abutment Design) is a patented process using 3D optimized scanning to generate an exact virtual image of the upper and lower implant-level models. It enables patient-specific solutions for single, multiple, and full arch restorations. The scanned image allows each Atlantis™ abutment to be individually designed for the specific space it will fit and in relation to the surrounding teeth. Using the Atlantis VAD™ (Virtual Abutment Design) software, Astra Tech designs the abutments from the final tooth shape, which is a significant advantage in achieving a more natural, esthetic result. The software analyzes the specifications we provide, such as details which enable us to make the final restoration according to the doctor's preferences for occlusal and interproximal contacts, and integrates them into the abutment design. Atlantis™ abutments are available in titanium, gold-shaded titanium (Atlantis GoldHue™), or zirconia. Each abutment is precision-machined from a solid blank of Grade 5 titanium alloy or zirconia.

Atlantis™ abutment in titanium

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 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 has the same features and benefits as the Atlantis™ abutment in titanium. However, 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 all-ceramic crowns.

 

Atlantis™ abutment in zirconia - white and shaded

Made of Y TZP (yttria-stabilized tetragonal zirconia polycrystals), the zirconia abutments are milled from a solid zirconia blank for unmatched strength and durability, color consistency, excellent biocompatibility and reduced plaque build-up in comparison to titanium. They are available in both white and shaded. The shaded zirconia material is available in four shades, of which we, the laboratory, would choose the one that most closely matches the final restoration shade.
