Profile

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

Follow nature's contour

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

It 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

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.

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

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

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
