Editor’s Letter
I have always thought it would be a good idea to do an
educational video that focused strictly on restorative
repairs, but this has proven to be a more difficult program
to put together than I expected. It’s not as if fractured
ceramic restorations walk through the door every day, yet
when they do, it sure is nice to have a good solution. So
I thought the next best thing would be a pair of articles
on repairs from Dr. Robert Lowe, a frequent contributor
to Chairside.
In Part 1, Bob shows you how he repairs a broken PFM
restoration with a porcelain veneer, or more specifically,
how he gives new life to an old PFM by “resurfacing” it with
a porcelain veneer. This strategy works well when the metal
substructure is not completely exposed.
In Part 2, Bob makes use of a “saddle crown” to cover a
fully exposed metal substructure, which he has prepared to
give the saddle crown adequate strength and esthetics. This
technique can be extremely helpful when you have completed
a large anterior bridge, for example, and something
chips or breaks within the first year.
The other thing that made me abandon the idea of putting
together a video on repairs is the shrinking number of
repairs I’ve had to do since becoming a predominately
“monolithic” dentist. In other words, I use a lot of
IPS e.max ® in the anterior and a lot of BruxZir ® Solid
Zirconia in the posterior, and I just don’t see either of
these restorations fracturing.
Even though I haven’t done a single-unit PFM in years, I
still use PFMs for bridges. As any bilayered restoration has
the potential for those layers to separate, Bob’s repair techniques
will continue to be useful for the foreseeable future.
Yours in quality dentistry,
Dr. Michael C. DiTolla
