Discover Simplicity without compromise

The Astra Tech Implant System EV is designed to make everyday work easier, without compromising the clinical outcome.

The design philosophy behind the Astra Tech Implant System EV is based on the natural dentition and uses a site-specific, crown-down approach supported by an intuitive surgical protocol and a simple prosthetic workflow.

By using Astra Tech Implant System EV you and all members of the treatment team will experience increased job confidence and satisfaction.

The following features of Astra Tech Implant System EV add value and simplicity to your everyday processes:

  • Versatile implant designs – straight, conical, sloped, short, narrow and wide, using only one surgical tray.
  • Flexible drilling protocol – provides preferred primary stability.
  • Site-specific restorative components – round and triangular options supporting your soft tissue sculpturing needs.
  • Unique interface – provides one-position-only placement for Atlantis patient-specific CAD/CAM abutments.
  • Self-guiding impression components – require only one hand for precise seating.

Astra Tech Implant System BioManagement Complex

Function, beauty and biology in perfect harmony

The foundation of the Astra Tech Implant System EV is the unique combination of independent features. These comprise the Astra Tech Implant System BioManagement Complex and ensure reliable, predictable and esthetic results both in the short and long term.

OsseoSpeed – more bone more rapidly

A chemically modified titanium surface with a unique nano scale topography that stimulates early bone healing and speeds up the bone healing process.

MicroThread – biomechanical bone stimulation

Minute threads on implant neck that offer optimal load distribution and stress values.

Conical Seal Design – a strong and stable fit

A conical connection that seals off the interior of the implant from surrounding tissues, minimizing micromovement and microleakage.

Connective Contour – increased soft tissue contact zone and volume

The unique contour that is created when you connect the abutment to the implant.

Marginal bone maintenance 

Backed by the well-documented Astra Tech Implant System BioManagement Complex, Astra Tech
Implant System EV provides proven long-term marginal bone maintenance and esthetic results. Literature demonstrates that the Astra Tech Implant System maintains bone better than the current standard norm for success.

A continuous evolution

Our groundbreaking innovations are the result of knowledge and understanding of the biological and clinical processes involved in dental implant therapy.

1985 – Clinical use of the first generation of implants with Conical Seal Design and Connective Contour is initiated in a study at the Karolinska University Hospital in Stockholm, Sweden.

1989 – The idea of blasting the implant surface with titanium dioxide particles to increase bone growth and osseointegration is presented and the TiOblast surface is born.

1990 – A team at the University of Oslo, Norway, conceives the concept of using a fluoride-modified implant surface to help speed up the osseointegration process. As a result, the first experimental pre-clinical studies on OsseoSpeed are initiated in 1993. In 2000, the first patient receives an OsseoSpeed implant at the University of Oslo. The first and only chemically modified implant surface – OsseoSpeed – is launched in 2004 at EAO in Paris.

1991 – The idea of minute threads on the implant neck to ensure positive biomechanical bone stimulation and maintained marginal bone level is born – MicroThread. After comparing 840 threads of different shapes and sizes, the optimal profile for positive stress distribution is identified.

2007 – Atlantis patient-specific CAD/CAM abutments are introduced for the Astra Tech Implant System.

2010 – OsseoSpeed TX is launched. TX stands for tapered apex and it is introduced on the complete implant assortment.

2011 – OsseoSpeed TX Profile, the unique, patented implant that is anatomically designed for sloped ridges, is introduced.

2014 – Introduction of the Astra Tech Implant System EV. The design philosophy of the implant system is based on the natural dentition utilizing a site-specific, crown-down approach. Featuring a unique interface with one-position-only placement for Atlantis patient-specific CAD/CAM abutments.

As you would expect from a system that promotes simplicity without compromise, integrating Astra Tech Implant System EV into your current workflows is equally uncomplicated.

OsseoSpeed Profile EV – A unique implant specifically designed for sloped ridges

OsseoSpeed Profile EV is specifically shaped for efficient use of existing bone in sloped ridge situations.

  • Provides 360° of bone preservation maintaining soft tissue esthetics.
  • Can help to reduce the need for bone augmentation.
  • Components designed to allow for accurate identification of the implant position throughout the treatment process.

360° bone preservation in sloped ridge situations

OsseoSpeed Profile EV 360 degree bone preservationIt is well documented that crestal bone resorbs after tooth extraction or tooth loss.

Often resorption is pronounced on the buccal side, resulting in a lingual-to-buccal sloped ridge. This situation occurs even if a standard implant is immediately placed in the extraction socket.

Because bone-to-implant support is three-dimensional, it is important to have marginal bone support around the entire implant.

Preserving the buccal and lingual marginal bone in a sloped ridge situation will also positively influence mesial and distal marginal bone levels, which optimizes soft tissue esthetics.

This is what we mean by 360° bone preservation in sloped ridge situations.

A better option for implant placement in sloped ridges

When a standard implant is placed level with the lingual bone, the implant neck is exposed buccally, compromising soft tissue esthetics. 

When a standard implant is placed level with the buccal bone, unsupported lingual marginal bone is lost.

OsseoSpeed Profile EV is placed level with both buccal and lingual marginal bone, preserving soft tissue esthetics, and can help to reduce the need for bone augmentation.

Simplicity and accuracy throughout your workflow

When working with a sloped implant neck, the ability to identify the location of the apical slope of the implant is critical to the simplicity and predictability of the treatment process. The enhancements within the OsseoSpeed Profile EV line are designed to meet this need while still offering flexible treatment solutions.

Self-guiding impression components for an accurate and predictable workflow

This innovative design provides a time-efficient installation procedure and a predictable workflow between the clinician and dental technician.

One-position-only placement of all indexed components

The unique one-position-only placement makes the entire treatment procedure simple and predictable, from implant placement to the connection of the final abutment.

Wide range of implant options

Available in straight and conical implant designs in 8–17 mm lengths.

Supported by the full range of digital solutions

Digital solutions from Dentsply Sirona Implants support you from the planning to the final restoration, offering the possibility of working with a completely digital workflow.

Clinical documentation 

OsseoSpeed Profile implants are being evaluated in several ongoing studies sponsored by Dentsply Sirona Implants:

  • 250 patients and 300 implants.
  • Healed ridges and extraction sockets.
  • Up to three years follow-up.

Main conclusions

  • High implant survival rate.
