The highly respected Journal of Prosthetic Dentistry has published two studies on the long-term survival rate of Prettau® Zirconia full-arch bridges. The first, in December 2017, found a success rate of over 99% over five years. The second, in March of 2018, again validated the exceptional success rate of the Teeth Tomorrow® protocol.
The Prettau® Zirconia dental implant bridge produced by Teeth Tomorrow Dental Laboratory is the final prosthesis delivered by the advanced implant dentists in the Teeth Tomorrow Network, an affiliation of highly credentialed practices delivering the Teeth Tomorrow® procedure in exclusive territories throughout the country.

Survival of 2039 complete arch fixed implant-supported zirconia prostheses: A retrospective study
This study is coauthored by Avinash S. Bidra BDS, MS; Michael Tischler DDS, FAGD, and Claudia Patch DMD.
The results were astounding. Of the 2,039 arches produced by Tischler (now Teeth Tomorrow) Dental Laboratory between 2012 and 2017, only 9 were returned for replacement. That’s a success rate of 99.6%!
Practice-based evidence from this large sample study demonstrates that Prettau® Zirconia virtually eliminates issues that have been plaguing both dentists and patients for years.
Rehabilitation of edentulous jaws with zirconia complete-arch fixed implant-supported prostheses: An up to 4-year retrospective clinical study
This study is coauthored by Michael Tischler, DDS, Claudia Patch, DMD, and Avinash S. Bidra, BDS, MS to address the limited data available on the clinical outcomes of patients replacing traditional removable dentures with non-removable full-arches of teeth supported by dental implants.
The study focused on 128 patients without teeth rehabilitated between January 1, 2013 and December 31, 2016, with a total of 191 upper and lower Prettau® Zirconia full-arch bridges supported by a total of 1072 dental implants.
The results demonstrated an amazing Cumulative Survival Rate (CSR) of 99.4% for the Teeth Tomorrow® bridges, and a 97.6% CSR for the implants.
All full-arch implant supported bridges are not created equal.
These studies demonstrate the clear survival advantage of the Teeth Tomorrow® Prettau® Zirconia full-arch bridge over other solutions that deliver acrylic hybrid bridges as the final product. Composite bridges made with acrylic gums and denture teeth (even when supported by a titanium bar that connects to the implants) are notorious for chipping, breaking, cracking, and losing teeth.
A recent comparison of the Prettau® Zirconia bridges used by Drs. Tischler and Patch versus acrylic bridges delivered using the NobelGuide®All-on-4® Treatment yielded some enlightening results* – Nearly 1 in 4 patients receiving acrylic bridges experienced chipping, breaking or cracking that resulted in the final bridge needing to be replaced.
The March 2018 study by Tischler, Patch & Bidra reported only 1 of 191 bridges required replacement, while the December 2017 study reported only 9 out of 2,039.
