The transition zone—a small space that plays an important role

Having your own teeth is truly priceless; wanting to open your mouth and smile improves your quality of life and preserves your self-esteem. Should a tooth need to be replaced, the next best thing is implant prosthetics that look and feel like natural teeth. This is what Atlantis patient-specific solutions are all about, and one key to their success is the transition zone.

There is no question about it. When a tooth restoration mimics natural tooth function and appearance the results for both the restorative team and the patient are great. Success restores the patient’s individuality and brings about a sense of well-being that is far greater than one might expect.

And, one small space plays a big part in this success. As Dr. Paul Weigl, Head of Department of Postgraduate Education at J.W. Goethe-University, Frankfurt am Main, Germany explains:

“The Transition Zone, where we have the soft tissue, is also a big point in the final esthetics. Especially in single tooth restorations.”

The transition zone is the tissue contact area below the cementoenamel junction (CEJ) up to the implant interface. With a natural tooth, the epithelium attaches itself to the root and cementoenamel junction (i.e., between the bone and the crown of the tooth).

Dentsply Sirona takes the transition zone very seriously, knowing that implant prosthetics should mirror, and have the same anatomical shape, as the missing tooth. An important part of the process is to design patient-specific solutions that replicate natural tooth function and esthetics.

“The abutment prepares the best base for the esthetics of the crown. The lines and shape are more nature-like, like a root to a crown,” continues Dr. Weigl.

With its patented Virtual Atlantis Design (VAD) software, Dentsply Sirona is able to design patient-specific abutments that take into consideration the edentulous space and surrounding soft tissue.

Working with these parameters, Atlantis abutments create a similar integration between the abutment and the peri-implant soft tissues in the mouth. And, in this way, create unique natural-like transition zones that ensure fantastic fit, function and esthetics.

But the transition zone is more than esthetics. To ensure a successful osseointegration, it is vital the right biocompatible materials are used. Atlantis offers abutments in titanium, gold-shaded titanium and zirconia to support the epithelium and contribute to long-term peri-implant health.
