Single tooth replacement in the posterior using the On1 Concept

By Dr Bernard Touati

Implant Prosthetics Implant Surgery

An important new addition to Nobel Biocare's assortment of components is the On1 concept. This innovative modular solution bridges the gap between the surgical and prosthetic workflows. The On1 Base connects to the implant at surgery and then remains in place throughout the healing process, prosthetic work and then the lifetime of the restoration. This leaves the soft tissue undisturbed without compromising on restorative flexibility, leaving the biological seal it creates in place for optimised healing. With two height options available, there is the flexibility to change the On1 Base should the thickness of the soft tissue require it in the short or long term - an option not available with tissue-level implants. As the healing cap of the On1 concept supports an intraoral scanning approach, conventional impression-taking procedures for delivery of the final crown can be eliminated.


The following case report from Dr Bernard Touati in France describes a single tooth replacement in the posterior region using the On1 Concept.
