You Should Know:
EZ-Pedo
by Krista Houstoun, Associate Editor, Dentaltown Magazine
E for "esthetic" and Z for "zirconia," EZ-Pedo Zirconia Crowns, offered in more than 1,000 offices in 15 countries, have completely
changed the landscape of aesthetic pediatric dentistry. Dentaltown Magazine met with founders Drs. John Hansen and
Jeff Fisher to learn more about the company that created the world's first pre-fabricated pediatric zirconia crown.
How did EZ-Pedo come about?
Hansen: The idea was born out of a need for my son who
injured his four front teeth when he was three years old.
Though at the time the best materials available were used to
fix his teeth, he still felt self-conscious about how his smile
looked. His restorations also kept breaking, requiring frequent
dental visits for repair. I knew there had to be a better way.
Working alongside nearly 50 pediatric dentists for more
than 10 years, Dr. Fisher saw firsthand the challenges faced by
pediatric dentists and the limited crown options available to
them. Soon, he began to develop ideas for how they could be
improved and surveyed pediatric dentists to determine the
characteristics they would want in an ideal pediatric crown.
One day, when Dr. Fisher provided anesthesia for my son, we
decided to take action.
Tell us about what EZ-Pedo provides to dentists.
Fisher: EZ-Pedo is the first company in the world to
bridge the gap between cosmetic adult dentistry and pediatrics,
providing a USA-made aesthetic monolithic zirconia
crown specifically designed for children. In addition, we also
have proprietary Zir-Lock Ultra breakthrough technology,
exclusively available from EZ-Pedo, which addresses the clinical
limitations associated with smooth-walled zirconia
crowns. Research shows that smooth-walled monolithic zirconia
crowns come off. That's why EZ-Pedo designed a crown
with built-in mechanical undercuts. Zir-Lock Ultra retention
grooves at the margin minimize cement loss on the inside of
the crown during cleanup, reducing micro-leakage at the margin
while ensuring maximum crown retention.
What are some of the challenging clinical situations
unique to pediatric dentistry, and how does
EZ-Pedo help to address these issues?
Hansen: The biggest issues with pedo are aesthetics and
durability. There seems to always be a compromise between
aesthetics and strength. With our product, there isn't a compromise
anymore. You get the best in strength as well as aesthetics,
and the tissue response is incredibly healthy.
Tell us about the evolution of the product.
Hansen: In the very beginning we approached our design
from strictly an aesthetic point of view. We tried to make a
crown that was very anatomic looking and looked as much
like a natural tooth as possible. However, because zirconia
does not flex, our original anatomic crowns required much
more tooth removal to get the crowns to seat. We changed our
design so it is a modified anatomic design. You don't have to
remove as much tooth structure, and it is still aesthetic. This
modified anatomic shape also allows our crowns to seat much
better in crowding or space-loss situations.
As practicing clinicians, we understand what the clinical
challenges are. At EZ-Pedo we do all our manufacturing
and design in-house. It is a huge advantage, because we
transfer that knowledge to our design to meet these challenges.
We have continually improved our product over the
years; in fact, we have made 12 design revisions of our initial
prototype introduced in 2007. So it might only be a
tenth of a millimeter here or a tenth of a millimeter there,
but the smallest details make a huge difference in how our
product performs.
What is EZ-Pedo University all about?
Hansen: I have been involved with teaching hands-on
programs in adult dentistry for many years, and it is the same
concept for aesthetic pedo. The biggest challenge that we see
when dentists try using zirconia crowns is that it is a very different
prep from what they are used to doing, so there is a
mind shift that has to take place. They will try our product,
struggle with it, then it ends up on the shelf. Doctors need
help with learning the preparation correctly and practicing it.
Once they get that, it's like the light bulb goes on, and for
many there is no turning back. What this program provides is
the scientific and didactic knowledge, but also a hands-on
component. EZPU is designed to provide doctors everything
they need to be able to successfully implement EZ-Pedo
Zirconia Crowns in their clinical practice.
