hello welcome to chairside live I'm Megan strong and I'm will Schmitt registered dental assistant
here at gladwell dental thank you so much for joining us today it's a good one you're gonna
be glad you did dr. mani Lily she's continuing her series where she's featuring the impression
process for taking an impression of a Brooks or full-arch implant prosthesis but in this episode
she's fabricating the implant verification jig that's right and she's ensuring a passive fit
of the eventual full arch Brooks her prosthesis so she's making sure that what you see exactly in the
mouth is translated to the master cast at the lab perfect well dr. manaan Lily let's see your jig
thank you guys just like Megan and will said in today's episode I will be demonstrating the use
of an implant verification jig it is a vital step when restoring implants as we know implants aren't
teeth they are rigidly fixated in place the more accurately you can capture the implant positions
the less stress you'll place on both the implants themselves and the prosthetic on top providing the
lab with a verified impression will allow them to create a beautiful passively fitting prosthesis so
let's get started and I'll demonstrate just how to use an IV J the first thing we are going to
do is remove the healing abutments and insert the multi-unit abutments or mu ace that were selected
by the lab these mu A's help idealize the implant angulation and raise the restorative platform to
allow for a healthier and more predictable restorative design once the MU A's are in
place we begin to see the implant verification segments these segments are made of temporary
cylinders looted together with a rigid material in the laboratory as you can see each segment
will come numbered making it very straightforward when placing each piece intraoral e there are two
things we want to check before moving on the first is verifying that the segment's do not touch as
this could prevent them from seating passively the second will be making sure each segment is
fully seated if you do not have mu A's in place it is important to have radiographic confirmation
in this situation however the MU A's have raised the restorative platform so we can visually verify
that our implant verification segments are fully seated and the radiographs are not necessary now
we are ready to connect the individual segments to do this you want to use a rigid material you
can use a Durrell a acrylic triad or a flowable composite as you can see I like to use flowable
composite because it is odorless easy to apply and is fast setting make sure that whichever material
you choose in your office that you fully connect the segment's together on all sides one of the
advantages to having the lab fabricate the ivj is that I know the bulk of the material has already
been added decreasing my chair time additionally it gives me the reassurance that there will be
minimal distortion due to bulk material shrinkage that can otherwise easily happen when you're using
large amounts of composite resin you DMA or PMMA now that the segments are connected we can try
our custom impression try in you want to make sure that you can easily unrepeatable a seat the tray
without the ivj catching on the holes for easy identification during the impression I like to
make sure the top of the lab screws are either sticking out or are flush with the custom tray
if you are having difficulty you can connect the holes creating one large trough this will make
it easier to seat the tray I like to add wax over the holes or trough that I created this will help
keep the impression material in place allowing for easy identification of the top of your ivj
screws the tray is painted with PVS adhesive and set to dry we will be using a combination
of both a light body and heavy body capture PVS impression material the lighter viscosity material
is float on the soft tissue underneath the ivj to ensure we capture the detail of our soft tissue
contours in our master cast at the same time my assistant fills the tray with a heavy body PVS
material one seated you can use the end of the mirror to help identify the tops of the screws
before the impression material fully sets after the PVS is set up it is time to unscrew the jig
I like to gently pull up on each lab screw to ensure that they are fully disengaged before
attempting to remove the impression now you can remove the impression and send this back to the
lab with that thank you for joining me today on another episode of chairside live next we
will continue this case and we'll walk through perfecting your wax rim and bite registration
thank you so much dr. Mandl illy and be sure to tune in to the next episode where dr. Manolo Lee
is going to go through these steps for the wax rims and the bite registration it's gonna be
a good one I think so but today this good ones all wrapped up so on behalf of everyone here at
Global Dental thank you so much for watching and we'll meet you right back here next time
you
