How is a crown done on your tooth
Replacing Crowns on Teeth #7-10 With BruxZir® Anterior
[Music]
okay so let's go over the case of the
week for this week and I want to present
a case that was actually completed by
dr. Anna Maria Mears on she is one of
our in-house dentists and she's also a
certified dental technician so an
extremely talented individual and this
case this patient presented for the need
to have for anterior crowns replaced a
seven through ten so dr. Mears and after
getting the patient numb went ahead and
removed the old crowns and now she's
prepping the margins and making sure
that any recurrent decay is cleaned up
from around the margins of these teeth
obviously you want to go through and
make sure that you clean everything up
after removal of the old crowns and
certainly there was some leakage around
these where they had to be removed this
technique in terms of the crown
preparation is the reverse technique I
like it because it gives you a set of
birds to go through in order to get a
final prep it gives you certain
guidelines so it's very helpful
clinicians have their own technique and
obviously if you're comfortable with the
way you're prepping teeth and you're
doing it right that's based on your
comfort level so again the reverse prep
technique works quite well and we like
it because it's a standardized way of
prepping the teeth so once the teeth are
prepared the laboratory actually has
fabricated a tooth prep guide that you
can seat on top of the preps to make
sure that you have enough reduction now
for the topic of our discussion we're
talking about Brookes interior and
because it's a brookster we can have
minimal reduction in order to fabricate
these crowns you want to go ahead and
check the bite and like I said before
the reduction guide is seated on top of
the teeth to make sure that you do have
enough reduction one little trick is
that you can always place a
through now the different areas of the
reduction guide and using your
periodontal probe you can check to see
how much reduction you have through the
actual reduction guide so once we know
we have enough reduction we can go ahead
and realign our bio temps and the
patient can actually go home with a set
of temporaries when the patient comes
back to have the final impression visit
if you don't do it at the same day of
the prep that bio temps are removed what
I like to use on what dr. Mears on use
in this video is ultrasonic to get rid
of the temporary cement it's very
helpful so you don't have to scrape away
at the temporary cement and then the
cod2 core technique is utilized so that
we can go ahead and capture the margins
so once the first chord is placed we'll
go ahead and refine our margins and make
sure that we have nice clean visible
margins and then the second chord is
placed along with some cotton rolls or
copper caps I really like using these
comp recaps because the the pressure on
the tissue helps the retraction and also
helps with the hemostasis around those
teeth so after a period of three to four
minutes we can go ahead and remove that
second cord that was placed and inject
the Lightbody and and the medium body or
actually in this scenario this is medium
body capture material along with heavy
body capture and pressure material so
once the impression material is set we
can go ahead and remove the impression
tray from the patient's mouth and we can
visualize the the margins that are
captured within the impression and
utilizing a triple tray I believe this
is a clinicians choice triple tray and I
like these because they're very rigid
you can go ahead and capture the area
where you want to impress one important
aspect of the Brooks or anterior is that
there is a bit of translucency in this
restoration and it's very important to
capture the stump shade and relay that
information to the dental technician so
that they know what they're working with
underneath the the final restoration so
once the sump shade is selected the
information is sent to the laboratory
and a technician can design and produce
the brucks from an interior restoration
and as you can see here they are very
well integrated into the patient's mouth
so I'm very excited about this product
it's a very good product and it brings a
little more translucency to the original
brookster line of restorations and I
hope that you get a chance to use it in
the near future
you
