Optimising The Prosthetic Outcome With The On1™ Concept
by: Dr. Giacomo Fabbri
My first reaction to the On1 restorative concept was, “Why hasn’t anyone thought of this before?” This innovative prosthetic component helps us to optimise the prosthetic outcome while providing a more comfortable treatment plan for the patient.
On1 gives us the opportunity to move the prosthetic interface of the restoration from the bone level to a more coronal position. This means that any biological or biomechanical complication that may arise at this interface will be at the soft tissue level rather than in proximity to the bone, enhancing —as I see it—the reliability of the prosthetic outcome.
Compare the On1 concept to traditional transmucosal implants, and you’ll find multiple advantages. First of all, the On1 concept implements platform switching at the bone crest level, thus facilitating bone maintenance around the implants. Additionally, the two base-height options—1.75 mm, and 2.5 mm—provide versatility. This means that we can select the ideal height in relation to soft tissue thickness.
Working with Nobel Biocare’s conical connection with platform switching means that we can work flexibly in terms of the vertical position of the implant, which can be located either at the bone crest level or below the bone crest. We can select the appropriate On1 Base height and choose the vertical position of the implant to adapt to the specific soft tissue thickness.
Thanks to the On1 concept, we can virtually manage any kind of clinical situation in reference to soft tissue thickness.
