today at LSK we're gonna discuss partials and the differences between each type
and what they're used for
All right, here we have a duracetal partial which is a tooth colored material
it is all injected in one piece the clasp and the framework so
we'll inject the clasp and the framework and it will come out like this then we'll
cut our retention holes in it and then set some teeth and send them out in a
wax try-in, if they want to do a wax try-in or we can go right to process
like this one we process the teeth and just regular hard acrylic it's an
acrylic base material so they do bond very well together but we still do the
mechanical retention just in case so why white instead of pink?
these are to better blend in with the teeth so these will blend, so if you look into
a patient's mouth you'll see tooth all tooth color over the teeth because
unlike our flexibles that are all one piece the pink covers a little bit
of the tooth and sometimes it makes the tooth anatomical, you know, crown, look a
little shorter and a lot of patients don't like that so we can do tooth
colored we can do pink and we can do clear on our flexibles this is what we
call a double shoot it's both types of clear are both types of flexible
material from TCS, this is Karadent clear and the TCS unbreakable so we'll shoot our
clear clasps first and then we'll cut holes, retention holes in them and
then shoot, invest the case, and then shoot the pink, so it'll pick up the
clear part, the clear clasp as well and become one underneath the tooth so
double retention there. We have an acrylic just a one tooth flipper a lot
of people like to call them flippers or temporaries it's all hard acrylic with
the processed denture tooth, and we always put two clasps on ours unless the
doctor indicates on the rx "no clasping" but we always like to
include a little bit of retention and then they could always cut it off chair-side
if they don't need it or it doesn't work out for them. So why would you use
that instead of like a bigger partial? For temporary, like an implant, if they're
doing a single tooth implant and they just need it until they get their
healing cap off and they go to restore that implant crown this could be a
temporary appliance we've had people stay in them for years they could just
be while the implants are healing during those stages as well. But usually only if
you're missing a few teeth? Right. This one is just another acrylic partial
replacing to anterior teeth, this one they are giving immediate extractions
and implants placed so they just wanted to replace the anterior teeth even
though they're missing posteriors they're just gonna use it very
temporarily while they're healing, so they just wanted something for aesthetics
only there. Usually we like to replace all the teeth. Would you be able to eat
stuff with those in your mouth? You can but, we don't suggest biting anything off with those
front teeth any kind of partial there's always that chance of fracturing because
almost your thinnest point of acrylic is gonna be behind the tooth so
we suggest taking even just the flippers out to eat. The flexibles are a little
bit stronger so you can eat with those but if they're anteriors we just don't
recommend to bite anything off or chew or anything really sticky that could
pull them out. We have another one tooth Nesbit another temporary option patients
do these a lot too over implants they get an implant and then doctor can adjust
for the healing cap we have these for temporary and then we do have a lot of
these for permanent restorations as well
this is another unilateral flexi we made a crown here so we put the new
flexi to the crown double check the bite there... good see how it covers a little
bit of the tooth that's why we'll do the double shoot
we recommend the clear clasp a lot for the anterior teeth. This is one of our
newer products clear frame partial where it's a single shoot just like the duracetal
the clasp and the frame is all one piece and then we'll process it on
just like this one, cut a few retention holes in it and then process
on the acrylic so you get a good duel partial as well good aesthetics and the
clasps blend into the tooth without trying to have to match two different
products we have a cast metal this is a combo cast metal where we do the
flexible clasps fabricate the framework process on the... or the flexible
clasps before the try-in so the patient can get the final fit of the partial at
the bite block appointment. So is there a reason you would use metal instead of just the
regular acrylic? Cast metal? yeah, it's a lot thinner you can see like some of the
thickness on this one's pretty thick to give you the strength this is a lot
thinner we can design it a little more open, open palate easier designs more
tolerated by patients because it's smoother and not as thick and doesn't
change their speech very much just about longevity as well. Would they use it longer then or...?
Absolutely, yeah, we don't give doctors a specific timeframe but with
patients teeth change and we they like to see them replace the cast metals
we've had them come back and patients are wearing them 30 years so anywhere
from 10 to 30 years depending on how they take care of it and
they use it and what kind of clasping they have when it needs a replacement
that's and then we could always if they lose other teeth we can laser weld mesh
onto these and add teeth as they lose them and then I've seen a lot of them
come back and they're full dentures now with the metal supports. So with the cast
metal then it's more for long-term and then also for ease of use? Right. Would
you be able to chew with the metal easier or not? Yes, these are made to wear while
eating so they have the lingual reinforcements here that's gonna
stabilize a partial in the mouth and the occlusal rest and the clasping, that's
all gonna hold it in place we can do regular denture teeth we can do porcelain
teeth and then we can do for the really deep bites we do metal occlusion,
metal linguals, steel spacings, then we'll either process on the denture teeth onto
the facial or build it with composite so this is for a patient that has a really
severe deep bite and they were knocking off all their other acrylic teeth on
their old partials so we made one of these and so we made a second one as a
sample so we can show in send photos to doctors so we'll send it we'll make the
framework set the teeth in wax, send it out for a try-in, they'll double check
the size, shape, and color of the teeth see if everything's good and we'll send
it back and we'll process for delivery
lingual plate and we can do lingual bars the designs are pretty endless we could
do a lot of combinations and with all of our cast metal partials we can do clear
clasping, pink clasping, and tooth colored injected clasping on all of our partials
alright, is very interesting case just finished with the post and core and then
we welded it with locator from zest company so first we made this and design
it second we made the rest see it then we made housing and then we finished
cast partial here and polish it and we finish it
this is incredible and there's only a less kid can do the one percent
laboratory can do so fits great perfect feeling full design the inexpensive
prosthetic for the patients as a really unique guide the now is ready to send
out the doctor's office maybe that's why they send me you honey right so here's
the before here's the impression okay here's the nametag okay that's good
another cool stuff we finish it er a attachment they made a cloud then put
the the female attachment after they took the impression correctly so we made
the tooth colored Duracell and we made a frame design and put it in the housing
we finish it this is the view pop and now we send it out to those
office
