Atlantis VAD™ (Virtual Abutment Design)
– designed from the final tooth shape



Utilizing the unique Atlantis VAD™ software,
Atlantis™ Abutments are individually designed
from the final tooth shape. The result is an
optimized abutment solution that offers the
best possible function and esthetics.
Atlantis VAD™ (Virtual Abutment Design)

• Proprietary software system designs
  abutments entirely in a virtual environment
• Utilizes optimized 3D scanning of casts
• Integrates technician’s specifications into
  design
• Automatically detects multiple features/design
  parameters
• Engineered designs ensure
  highest level of precision
Designed from final tooth shape




The scanned model is               When the desired tooth shapes    The final design is checked for
transformed into a 3D image,       are decided, the abutments are   fit and occlusal clearance before
making it possible to create the   designed                         the abutments are produced
final tooth shape.
Atlantis VAD™ is beyond CAD
•   CAD abutment design is humans doing design aided by computers
•   Atlantis VAD™ is computers doing design aided by humans
•   Part of an integrated, highly optimized process
•   Specialized to abutment design
    – Creates an optimal design to begin with based on
       • Anatomy
       • Engineering
       • Manufacturability
    – Never permits an invalid design
Value of Atlantis VAD™
• Esthetics – based on the natural tooth shape
• Function – retention, anti-rotation, crown function/failure
• Mechanics – undercuts, fit, low-fracture
• Compensates for misalignments of the implant
  – angulations, offset
• Open for cooperation and partnerships, such as 3Shape,
  Dental Wings and 3M

Atlantis™ interface design philosophy
All interfaces are designed within the constraints of the
particular implant and include:
• Insertion feature for simplified handling
• Seating surface necessary to maintain tight seal and stability
• Anti-rotation features that also allow the abutment to be
  accurately indexed to the implant
• Each abutment screw is designed to work optimally with the
  specific connection and to correspond to the manufacturer’s
  torque driver

Notas do Editor

  1. Atlantis is comprised of a unique combination of four key features, which together, make the Atlantis BioDesign Matrix. These features work together to support soft tissue management for ideal functional and estheitc result. This is the true value of Atlantis for dental laboratories, clinicians and implant patients.
  2. Atlantis VAD ™ (Virtual Abutment Design) is an expert system software that designs abutments entirely in a virtual environment. It ’s smart software that can take all of the information input and transform it into an initial abutment design. Atlantis VAD utilizes optimized 3D scanning of casts to create a virtual copy of your case. It then integrates your specifications into the initial engineered design. Engineered designs ensure highest level of precision no matter what the interface or material.
  3. Atlantis VAD™ designs each abutment from the final tooth shape. It starts with the end in mind and then makes the abutment work for the restoration. With stock abutment restorations, the crown is adapted to suit the abutment – with Atlantis VAD – the abutment is adapted to fit the crown! This gives you the ability to follow traditional crown manufacturing techniques and creates a more esthetic and functional restorations.
  4. When designing an abutment, there are some basic ideal values that one would look to achieve. In this example, what you see is an abutment that is designed to follow the parameters of these ideal values where there is a 0.5 mm shoulder width, a taper of 2.5 degrees, and the path of insertion is even in distance to the neighboring teeth on either side. However, the distal core (on the left) is thin and what we would like to achieve instead for this particular case, is an optimal goal (CLICK MOUSE TO BRING UP) of increasing the distal height of the abutment.
  5. When working manually to redesign the abutment to reach the ideal goal, one option would be to leave the shoulder height value the same and adjust the degree of taper. When the degree of the taper is reduced the fit of the coping to the abutment may become too tight. In this example, you can also see how when decreasing the taper by one degree, you also decrease the space between the abutment and neighboring teeth and while this also increases the distal height of the abutment closer to the optimal goal, it still does not reach the desired goal.
  6. In this second design change option, the original shoulder and taper values are left the same, while the path of insertion is offset by three degrees distally (left). While this change does bring us closer to the optimal goal, it is still not fully achieved. In addition, changing the path of insertion can sometime cause other conflicts with such things as parallelism needed. And in this particular case, the mesial (right) porcelain offset is increased too much as a result of the change.
  7. Yet another possibility, is to adjust the distal (left) shoulder width. Here you see an example where the distal shoulder width is reduced by 0.2 mm in order to produce the optimal goal for the abutment design. Unfortunately, this change also creates a situation where there is only 1.0 mm of space on the distal side for the porcelain.
  8. Here you see an abutment design that utilizes Atlantis VAD optimization. Atlantis VAD is a sophisticated technology that has all abutment design expertise, design considerations and parameters and manufacturing constraints and requirements built in. This allows Atlantis VAD to make small changes to all the parameters to achieve an optimal trade-off to create an optimal balance of all design considerations and constraint to develop a unique and optimized abutment design – consistently, every time and for every case. It allows for results that can be achieved by a human only if they had infinite time and computer-like patience.
  9. One of the challenges to getting great implant restorative results stems from the fact that implants are round but teeth are not. You have to transition somehow, from round implant to tooth-shaped crown. If you use a round stock abutment as the foundation for your tooth-shaped crown, you cannot transition from round to tooth shape until you reach the restorative margin of the abutment. If you place the margin near the tissue to allow for easy cement removal, you get “potato-on-a-stick” restorations or “lollipop” restorations that don’t resemble real teeth – they look like implant crowns.
  10. Another option is to set the margin very far sub-gingival in order to give the crown more room to make the transition. This results in a more natural looking restoration but can create a difficult situation for cement removal. As you know, cement left behind is one of the key reasons for implant failure post integration and can also cause fistulas and infections.
  11. With patient-specific abutments, the anatomical abutment design allows for a natural looking restoration and cement removal is made easier because the abutment margin can be designed to be where you want it.
  12. You have a lot of control in how your Atlantis Abutments are designed. The “Emergence Width” choice you make has the single largest impact on how the abutment is designed. Depending on what you select, the abutment can come back looking very different so it’s important to understand these choices and how they influence design. We’ll walk through each one in detail.
  13. Full anatomical dimensions Largest diameter abutment provided with best emergence profile possible. A surgical incision for placement may be required. 2. Contour soft tissue Medium diameter anatomically shaped abutment up to 1.0 mm larger than sulcus of model of soft tissue provided. 3. Support soft tissue Anatomically shaped abutment will be up to 0.2 mm larger than sulcus of silicone model of soft tissue provided with desired emergence profile. “Easy” insertion. 4 . No tissue displacement Smallest diameter, non-anatomically shaped abutment with no soft issue support. The abutment will not touch the soft tissue.

  15. The result, is optimized and predictable adaptation of the soft-tissue.
  16. When we created Atlantis™, our vision was to provide dental implant restorations as individual as every patient, every time and for every major implant system – unique originals for unique individuals.
  17. In the development of all interfaces for Atlantis Abutments, the key functional aspects that impact product handling and performance are carefully evaluated, including ease of insertion, the presence of a tight abutment-to-implant seal, anti-rotation and an abutment screw designed to correspond to the implant manufacturer ’s torque driver and guidelines.
  18. There are three basic categories or types by which abutment-to-implant connections can be described, as shown in this diagram. The connection type influences how the three key functional aspects of insertion, anti-rotation and seal is addressed.
  19. For NA the regulatory authority is FDA.
  20. An example of one way Atlantis™ Abutment interface designs are analyzed and optimized is through the use of a finite element analysis, which is a computer-based form of stress analysis that is performed to evaluate stress distribution as a result of load to ensure that all Atlantis Abutment interfaces are optimized for strength and reliability.
  21. A consistent process is also followed in the development of Atlantis™ Abutment interfaces, which include (read bullets) .
  22. The consistency of design and extensive quality testing and control processes allows us to provide our customers with (read bullets).
  23. Only the unique combination of the four key features of the Atlantis BioDesign Matrix working together can ensure optimal soft tissue management for ideal functional and esthetic results. This is what differentiates Atlantis from your traditional stock components as well as other so-called “CAD/CAM” solutions.
