Why Go Flat When the Ridge is Sloped?

Are you working harder because of convention?

How do you decide where to place an implant in a sloped ridge? If you align it with the buccal bone, you risk the loss of unsupported lingual/palatal bone (Figure 1). Alignment with the lingual/palatal bone will leave threads exposed buccally, compromising soft-tissue esthetics (Figure 2). To best manage either of these situations, bone augmentation procedures may be required, increasing chairtime.

Anatomically Designed

For patients with sloped ridges there is an implant specifically designed to follow their anatomy. In sloped ridge situations, OsseoSpeed Profile EV is the ideal solution for preserving the marginal bone and supporting the soft tissue all around the implant (Figure 3).

Simplicity and Accuracy

OsseoSpeed Profile EV Implants are available in a wide assortment of straight and conical implant designs ranging between 8-mm and 17-mm lengths. From implant placement to the connection of the final abutment, the unique one-position–only, implant-abutment interface makes the entire treatment procedure simple and predictable.

Efficiency and Esthetics

Using OsseoSpeed Profile EV can help eliminate the additional chairtime needed for bone augmentation procedures, while also supporting the existing hard and soft tissue needed for long-term esthetics.

It’s Documented

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.

The implant neck is exposed buccally when a standard implant is placed at the lingual bone level.

Unsupported lingual marginal bone is lost when a standard implant is placed level with the buccal bone.

Figure 2

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

Example of the implant matching the mesio-distal anatomy in the anterior region. The preservation of bone with the OsseoSpeed Profile EV implant prevents the need for osseous recontouring and increases the conditions for a more cosmetic outcome.

Figure 5

The molar implant demonstrates the ability for the Profile EV implant to match the commonly uneven changes to the bone anatomy. The benefits include bone preservation, thereby eliminating the need for the surgeon to reshape the bone to match the implant.
