The Historic Quest For Bone Preservation

Ancient civilizations searched for ways to preserve bone.
With the proper tools, they were able to prevail!

The Latest Advancement In Bone Preservation...
The Certain® PREVAIL® Implant:

• Designed to potentially enhance crestal bone preservation by medializing the Implant-Abutment Junction (IAJ) with Integrated Platform Switching - The intentional placement of a smaller diameter abutment on a larger diameter implant platform
• Innovative surface technologies that extend up to the seating platform to increase surface area and Bone-To-Implant Contact (BIC)
• Featuring the Certain QuickSeat ® Connection with an audible and tactile click confirming proper abutment seating
• Now Available: NanoTite™ Tapered PREVAIL Implant; ideal for cases where a tapered shape may be preferred and early stability is desired
• Straight collar design for tight interdental spaces or where ridge width is limited
• Expanded collar design maximizes cortical bone contact to provide crestal locking

The Prevailing Biologic Width Hypothesis⁵

The key driver of crestal bone remodeling is an important phenomenon that occurs around natural teeth and implants called the biologic width – the natural seal that develops around any object protruding from the bone and through the tissue into the oral environment. This seal isolates the bone from the oral environment.

Around natural healthy teeth, the biologic width consists of approximately 1.0mm of connective tissue and 1.0mm of epithelium. On top of these two tissue layers is at least 1.0mm or more of sulcular depth. The biologic width term essentially pertains to the physiologic attachment apparatus made up of the connective tissue and epithelium – or approximately 2.0mm. When implants are initially placed within bone and then covered with an adequate layer of soft tissue (first-stage surgery), there is typically little or no crestal bone resorption. When the implant is uncovered (in second-stage surgery) and connected to an abutment, the body then reacts and in the process of creating the biologic width, the crestal bone may resorb.
