Implant Restorative Study Club March Follow-up

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.

THE NEW POWERHOUSE IN IMPLANT DENTISTRY

The freedom of unlimited possibilities– patient-specific CAD/CAM abutments for all major implant systems

Atlantis BioDesign Matrix™

Atlantis VAD™ (Virtual Abutment Design)

Soft-tissue Adapt™

Custom Connect™

Designed from the final tooth shape

Optimal support soft tissue sculpturing and adaptation to the finished crown

Strong and stable fit –customized connection for all major implant systems

Natural Shape™

Shape and emergence profile are based on the individual patient anatomy

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.

• 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 ensurehighest level of precision

Atlantis VAD™ (Virtual Abutment Design)

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.

Soft-tissue Adapt™ – optimal support soft tissue sculpturing and adaptation to the finished crown

The design of each Atlantis™ Abutment takes biology, anatomy and engineering principles into consideration, providing the right conditions for soft tissue to heal and adapt to the finished crown.

Custom Connect™ – strong and stable fit – customized connection for all major implant systems

Atlantis™ Abutment connections and abutment screws are specifically engineered and tested for each implant interface for optimal fit, stability and a successful result.

• Astra Tech

• BioHorizons

• Biomet 3i

• Dentsply Friadent

• Keystone Dental

• Nobel Biocare

• Straumann

• Sybron Implant Solutions

• Zimmer DentalAll trademarks are the property of their respective owners.

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

Implant interface connection typesA B C

A) Deep conical sealwith indexing feature

B) Planar or shallow cone with internal connection

C) Planar seating surface with external connection

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

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.)

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

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
