Locator Troubleshooting – Fixing Denture Retention Issues By PREAT Corporation


In this video we’re going to talk about
locator troubleshooting and in particular denture retention. Chris, talk to me what goes wrong
when it comes to denture retention. Sure sort of start off probably the call
we get the least is that there’s not enough retention. If there’s too much
retention we already talked about how to replace the inserts how we can go from a
five-pound insert down to a one-pound insert. Okay. When we get the calls that
there’s not enough retention the first thing we want to take a look at is
what’s causing that. So, often, what we’ll take a look at is we want to make sure
that the abutment cuff eye is sufficient to provide retention. There needs to be
1.5 millimeters of the abutment above the gingival to allow the male to fully
see. Okay. If there’s not that 1.5 the male’s gonna try and see a contact with
the gingival and sponge right back up. Right, here’s the lack of retention.
Absolutely. So a simple test you can run in this test also lets you know if the
abutments are worn is to take an impression coping snap it on the
abutments in the mouth and as you go around the mouth you’re making sure that
number one the impression coping fully seats and number two the abutment is not
worn because you can feel with finger pressure the retention. Right. So it’s
either not even climbing going down properly or it’s feeling sort of like
that Wiggly. Correct. Okay. So in this case the first unit the first abutment had
good retention good fit the second the coping can’t see it all the way this
abutment is too low. There’s a line of demarcation you can see around the
abutments and when you eyeball that in the patient’s mouth if you don’t see
that line we need a taller calf ID above it. Okay. So for this case what we’re
going to do would be to remove the abutment that’s too low. We’re going to
use the appropriate tool. This great cuff height measuring tool place it right on
top of the platform to measure the cuff fight we need. What’s nice about this
tool in particular we can also use this to gauge if we need an angulated above
it or with locators extended range males. Now that we know what size abutment we
need we will simply thread the appropriate abutment. I mean this looks
like a pretty clear quick operation pretty quick process. It could be but
again we’re working in a patient’s mouth so nothing is ever reposition the
housings and we have retention. The other thing that can happen sometimes is that
if the patient impacts food inside the middle of the abutments the inserts with
the center plugs the pink the blue the clear cannot fully seat in that food or
calculus or debris that’s inside the center of the abutment needs to be
removed. So if you have a patient with poor hygiene the extended range males
the orange the red and the green that don’t have the center plug can sometimes
compensate for that person that doesn’t exercise good hygiene. Okay. In fact one
of the the next troubleshooting after going through the impression copings
checking the cuff heights if it was a retention issue would be to exchange the
standard inserts with the extended range males
they’ll pivot more they’ll compensate for divergence of the implants and again
replacing the extended range males get a good firm solid fit. All right so solves
that retention problem? Correct. All right cool. Thanks very much I appreciate that.
