Point of View recording of a CEREC bridge preparation tooth 28-30. Actual bridge preparation time 10 minutes. Design time accelerated to 3x speed.
Thanks for tuning in again. This is another point of view
video recording of a bridge preparation from tooth number
28 to tooth number 30. I think the angulation is pretty close.
It's from a head mounted camera with a 3.5 magnification
ocular. It should be pretty accurate. However, the
angulation is slightly different from what I see in my eight
power surgical loops. So there are a couple of times when the
handpiece or my hand will actually block the view when in
reality, through my loops, it's not blocked. I'm looking to get
a slightly more slightly high powered ocular for the camera
lens so that it's not quite as grainy, there's a little bit of
graininess, it's not quite as clear. And then I've got to
update some of the white balance settings on the camera to
improve that some of it gets a little bit washed out. But
generally, I think it's a good video. So the total elapsed time
on the preparation is roughly 10 minutes. There's some edits
here that you won't see there's some little transitions where
there's some fades from one clip to the next, where I had to
change a burr or we had to refill the distilled water
bottle. But yeah, generally, it was about 10 minutes. I usually
tell my patients that each tooth preparation for a crown assuming
a normal situation takes about five minutes. However, sometimes
they're a little bit longer depending on the situation, you
know, upper second molars can be a little more difficult to get
to just because of access. Sometimes the lower posterior
teeth can also be a challenge just because of access. Anyway,
all that being said, the elapsed time on the preparation was
roughly 10 minutes, give or take here there. And then immediately
after this preparation video, it'll jump right into a screen
recording of the bridge design. So this whole appointment, we had
a lot of three hours for this patient. The actual time the
patient was in the chair was, I think, I think we had the
patient in the chair for about 90 minutes at the beginning. And
then there was a roughly one hour delay. And then for the
cementation after, maybe it was longer than that, after the
patient returned from a break, after leaving the office while
the machine was milling the bridge and we were firing it in
the furnace, the cementing took 45 minutes or so, plus the
post-op x-ray and some occlusal adjustment. So maybe it was
three and a half hours when we totaled that all up. But at the
beginning, you know, if you break it down, 15 minutes of
anesthesia, plus a little bit of prep time, if you get started on
the preparation at about the 30 minute mark into the
appointment, and get all the scanning, imaging, designing
done by about the first hour, including the preparation, then
honestly, you should be able to complete a bridge like this in
less than three hours. I usually give my patients an opportunity
to leave. So we're not necessarily sitting there, but
I want them to know that they don't have to leave. Some are
embarrassed or uncomfortable leaving with an un-faced or
with, you know, their teeth prepped down. So this patient
did leave and then came back a little while later. Turned out
to be a great case. I've got some post-op pictures I'll try
to plug in here in a little bit. Our post-op x-rays rather, I am
looking at the post-op x-ray, my lead assistant missed the x-ray
that included the entire abutment, anterior abutment. So
it's a little bit cut and then there's some extra cement which
she removed from underneath the pontic space. But the bridge
itself looks good. I did not get an intraoral post-op picture. I
wish I would have. Maybe on a recall, we can get one from the
patient on a recall appointment. So great case. I mean, pretty
straightforward, pretty routine stuff. I usually do, you know,
as much as possible in one appointment. So the patient has
a quadrant of dentistry they need. I have no problem doing
the bridge and a couple of crowns or several crowns or root
canals. Tends to be a little more effective. There is some
other work this patient needs that we may do down the road.
But we had opted, whether it was time-wise or financial reasons,
to go and focus first on the bridge. So turned out great.
Nice opportunity to create a little video for you. Hopefully
you'll enjoy. The point of view kind of enlightens, you know,
allows us to see a little bit more. For those of you who may
not necessarily spend a lot of time doing dentistry or have not
had a lot of experience in the clinical side of things, this is
an interesting view. So right here you can see some bleeding
in the gums. That's fairly common. You know, I like to tell
my patients, you know, gums tend to get angry when we're spinning
a handpiece at 5,000 revolutions per second down next to them.
They don't like that too much. And that's pretty common. But as
you can see later on, a little bit later on, I'll pull out some
viscostats and aluminum chloride and scrub it along the gum line.
I don't normally use a lot of cord. I don't interact a lot
with cord. I haven't used cord in quite a while. Usually I feel
like if I prepped the tooth, I know generally where the margin
is. And so I have no problem going ahead and outlining my own
margin. That begs the question, do you do most of your own crown
and bridge design? I really do. I do almost all if not 100% of my
own CEREC design. I've been using CEREC since 2006. And I'm
pretty quick at it compared to my dental assistants. And I trust
several of them to do the CEREC design. But I'm much, much
faster. So I feel like there's value in the time saved. Overall
for me to take three or four minutes designing a crown or five
or 10 minutes designing a bridge versus them taking 30
minutes designing a crown or an hour designing a bridge. I'd
much rather just do it the way I'm comfortable with. And, you
know, dentists generally have a better grasp on some of the
crucible anatomy and, you know, interdigitation of the opposing
arches and yada, yada, yada. So I usually do most of my own
design work. Here is the viscous stack going in. Like I
said, this is aluminum chloride, I generally don't use ferrous
sulfate. I personally prefer aluminum chloride, the ferrous
sulfate tends to clump. And I'm not a big fan of that. Plus, we
get some patients that are allergic to sulfa drugs, and I
don't want to risk the ferrous sulfate causing an allergy for
a patient who may not have disclosed that. Yeah, aluminum
chloride works really, really well, good scrub and rinse and
then you get a pretty darn good margin, clear margin. Now, if at
this point, you don't feel confident that you can
marginate, then putting some port in would be a good idea. I
feel pretty comfortable with those margins, especially since
I prep them, I know where they are. And like I always tell, you
try to coach, if you're ever in doubt as to where your margin is,
take it a little bit outside, you can always adjust that margin
back when you're bonding in or after you bond in. If you're too
narrow, I'd rather be too wide than too narrow. So here's the
bridge design, you can see we have it set up as a bridge with
the anatomic intersection space, intersection shape rather. Go
ahead and image the lower and the upper and then go through
the design process, pretty straightforward stuff. Again,
this is an Omnicam. This is a six year old Omnicam, pretty
clear margins. There's little carries there on the facial at
27. One of the nice things about the software 4.5, you can see
that dark shadow there, which turned out to be rock solid,
that's just stained from an old silver filling. So I stopped
removing it when I discovered that was rock solid in that
decay. But the 4.5, I'm sorry, the 5.2 software really improved
the imaging of the Omnicam dramatically. So it allowed
allowed the Omnicam to function a lot better. One of the offices
that I'm partnering in has the newer PrimeScan. And I'm still
trying to get used to the touchscreen and the trackpad
versus the trackball. I, to be honest, I'm not quite a fan of
the PrimeScan yet, primarily because of the trackball and
the touchscreen. Granted, I've only used it for a couple of
days, but I'm so used to having that tactile feel with the
trackball that I'm not, I'm not, I'm not 100% sure I'm
going to really enjoy the PrimeScan for a while. But like
most things, once I'm used to it, I'm sure it'll be fine. So
you can see there, I grabbed a piece of a patient's napkin
while I was imaging and didn't realize it for a minute. So we
gotta go back and delete that. Delete that memory scan. Anyway,
the rest of the design process is pretty straightforward,
pretty simple, not a big deal. You can watch the whole imaging
process.
