IRSC Follow-up
Mr. Fred Senne, the guest speaker (Dentsply), kindly allowed us to give you his slides for reference.
Please contact us if you have practice questions or would like to see certain topics presented at IRSC.
We look forward to seeing you at the next IRSC meeting on May 9th. The topic is: The Fixed Hybrid Denture Solution with 4-6 Implants Using the Straumann Dental Implant System presented by Brad Cates of Straumann.

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.

Designed from final tooth shape
The scanned model is transformed into a 3D image, making it possible to create the final tooth shape.
When the desired tooth shapes are decided, the abutments are designed
The final design is checked for fit and occlusal clearance before the abutments are produced

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

Natural Shape™ – shape and emergence profile are based on the individual patient anatomy
The unique anatomical shape and emergence profile of the abutment nourish long-term soft tissue management and provide optimal support and retention for the final restoration.

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
Atlantis™ interface design philosophy

Atlantis™ quality
• Atlantis™ abutments are required to pass the same testing protocol for regulatory authority clearance as implant OEM products
• Atlantis products are subjected to extensive mechanical testing including extreme geometries (maximum angle, maximum length) in both static and fatigue loading conditions
![Page 31: Implant Restorative Study Club March Follow-up](https://reader035.vdocument.in/reader035/viewer/2022062615/548d12e6b4795945138b4b7a/html5/thumbnails/31.jpg)
Engineering analysis on Atlantis™
interface designs• Finite Element Analysis (FEA) performed for
every interface design to optimize strength of critical regions
• Validated by mechanical testing
• Various configurations tested
• Component designs optimized via FEA & testing (wall thickness, radii, etc.)
![Page 32: Implant Restorative Study Club March Follow-up](https://reader035.vdocument.in/reader035/viewer/2022062615/548d12e6b4795945138b4b7a/html5/thumbnails/32.jpg)
Atlantis™ interface design
• All dimensional features of an implant are first characterized in great detail
• Detailed dimensional data are analyzed using statistical methods
• Interface design variables are analyzed and designed to match or exceed functionality of the OEM connection for:
– Ease of insertion
– Anti-rotation
– Precision seal/seating surface
![Page 33: Implant Restorative Study Club March Follow-up](https://reader035.vdocument.in/reader035/viewer/2022062615/548d12e6b4795945138b4b7a/html5/thumbnails/33.jpg)
Atlantis™ Abutments
• Consistent quality of fit, independent of implant system (higher precision of fit for some interface designs)
• Reliability of functionality equivalent to or better than OEM
• Confidence of FDA cleared product that’s backed by extensive design analysis and mechanical testing
