The Certain® PREVAIL® Implant:
The process of Platform Switching has shown exciting possibilities in preserving crestal bone. The key to achieving consistent crestal bone preservation may be the intentional placement of a smaller diameter abutment on a larger diameter implant platform.
The experience of platform switching with smaller diameter abutments on larger diameter implants may demonstrate possible preservation of crestal bone and a less angular component to any bone loss. The working hypothesis is that any inflamed connective tissue or component micro-motion actually occupies a more medial location on the implant platform. Because it essentially is resting on the outer circumference of the implant platform, the inflamed connective tissue does not extend laterally to the same extent as it does with a traditional matched Implant-Abutment Junction.
Conventional Implant-Abutment Junction exposes the bone to the ICT
The crestal bone clinically and radiographically appears to maintain its position, while the soft tissue appears not to recede as much as it does with traditional “matched” configurations. In a sense, this implant configuration appears to limit biologic width reformation because the ledge of the implant platform, to a significant extent, may isolate the underlying bone.4, 5
Certain PREVAIL Implant contains the ICT, thus potentially reducing remodeling
By moving the IAJ in from the implant shoulder as we see with the Certain PREVAIL Implant, the bone may be shielded from potential irritants.
As a result, the bone may not cup in order for the biologic width to move down and seal it from the source of irritation. If the bone stays up, there is increased support for the soft tissue.4, 5
