DC-Air™ Zero Profile® Holders: Correct Assembly and Use

Now I'm going to show you how to use the bitewing holder first to put this together this slide here in the front and the stick snap in The stick and you will use one of the shorter sticks for the bitewing holder then replace the ring Slide the ring on the holder on here the smaller end is marked Mesial This is marked distal on this the smaller end is marked distal and the mesial is the larger end So I'm going to put the rounded edges of the sensor Going back towards the distal. That's the way you'll do 95% of your your x-rays like so So we're going to go ahead and place this in Hold with two hands so you can control the tongue In control the tongue and as they're biting you pull towards you so it's against the teeth bite together open bite perfect and now I'm going to again take the collimator pass through and Make sure I am exactly parallel stick parallel and take an image and remove So now we have somebody who has tori, smaller tori to medium or small mandible, or you really want to concentrate on getting the distal of the cuspid. You remove the sensor from here, placing it in your hand like so, taking your thumb and pushing, sliding out, and we're going to now flip this over so the rounded or comfort end is now facing mesial. Snap it in. So now, rounded facing the mesial. So it's going to go in like so. So now what I'm going to do is place in the mouth, hold on to here, relax to paint it in, and as you're slowly closing together, you pull forward until it actually stops moving forward and bite together.

You'll take the column there, pass it through, but you're going to pass it through more on the mesial side of the ring to give you a little better chance of capturing that cuspid. But again, very important, these two are parallel, and we'll go ahead and take a collimator and the sensor, and we'll show you both of those x-rays in a minute.

and as you can see we got distal to the second molars on the first one and we got the distal of the cuspid on the second one where we flipped the sensor. So you can see that's very easy way to get that. I'm going to have the patient open up now and show you that she does have small tori and we did it with small tori.

They're now going to work with the anterior holder the anterior holder looks like a chair and The proper way to place the anterior holder or the chair is to have each chair back where the sensor is flat And I've got the ring off for now just to show you and I'll put that in and I'll put the ring back on So what we'll do is we're going to take a Shot of eight and nine Chair like so In And then up have the bite and it's that simple Open I'll show you again with the ring on now Lastly, there is a midline and that midline goes between the embrasure of The teeth that you're looking for. So if I'm going for eight and nine I'm gonna go put that right in between the embrasure of eight and nine. So We'll take it like so chair down have open in And close line that up. It's right between eight and nine Now key again column there parallel against the nose but Perfectly inside the ring and parallel To I'm going to make sure this is Absolutely right on it for you. And then we're going to take an image again remove collimator and Take out And here is the result, a perfect aligned anterior image right in between the centrals. And you can pick up the lateral roots also.

That's what I'm going to show you how to use the anterior holder to get the lower This time we're going to show you how to get the anterior This time I'm going to use the anterior holder and get the lower anterior Same concept as the upper, but it's the opposite. So instead of the chair being like so The chairs like so because we're going on the bottom. So take the take this Place it in Slide it up Bite together Collimator through the ring And Parallel like so It's got to be parallel to the ring and we're going to go ahead and take an image And here is your lower anterior image. As you can see, apices of all four of the lower anterior teeth that you're looking for.

I'm now going to show you a trick for getting lower bicuspids. One of the tougher x-rays to get the apices. You use the anterior holder to do this, and it works the same way as it does for the anterior portion. I'm going to take the ring off to show you so you can see more clearly. Again, it looks like a chair. This is the back of the chair where the sensor is, flat.

We're going to have that flat this way because we're going under the mandible. We'll go ahead and place it. We want to get the bicuspid, flat in, bite together, and then you can place the ring on open. I'm going to show you now with the whole of the ring and the sensor together. Again, we got the chair flat. Have them open. Pick the tooth that you're looking for, the bicuspid.

Again, in, up, bite, column in parallel, and we'll take an image and then have them remove it. And there you have it. We'll take a look at the image right now. And here is the image for the bicuspid. You can see we got apices of both bicuspids and the apices of the cuspid.

I'm going to show you how to use the anterior holder to get the most difficult X-ray in the mouth, the apices of the lower bicuspids. So we're going to use this as a vertical holder. What you're going to do is you're going to use this flat, the chair, back flat, and it's going to go in the lower area here. And what you'll do is you'll place this in up and to the bicuspids and have them bite together.

Push the ring here. Again, make sure the collimator is parallel to the stick against the cheek. And we're going to go ahead and take an image. again parallel to the ring.

Hello today, I'm going to show you how to use a Zero Profile posterior holder and it's multifunctions First we're going to just do a upper Post here shot and show you how to place it properly you hold the holder with two hands One towards the ring and one at the bottom of the base of the holder We'll now place it Into the patient's mouth. We're going to do an upper and you'll notice Right in here you want to Put your finger on and have them slowly close And as they're closing you push back and bite all the way together It's now engaged Once it's engaged, you're going to line up very simply the collimator parallel To this stick make sure it's as close to the cheek or on the cheek if possible And we'll go ahead and take an x-ray after the x-ray is taken. You'll go ahead and remove the collimator remove the sensor In here, as you can see, a perfectly aligned posterior image all the way back towards the first molar without patient discomfort.

So this one I have set up for a lower posterior on the right side and to give the patient a little more comfort and with this holder what you'll do is you'll place it in the same way on the lower where you're pushing putting in and retracting the tongue sliding it back having them close slightly and as they close you push back with your this finger on the plastic and they're biting together you'll take a cotton roll and you'll have them just open a little bit put the cotton roll in between the teeth and the and the yellow plastic and have them bite like so that cushion gives them a little extra comfort and you can see she's not fighting this anymore and it's a lot less pressure on her muscles so we're going to now place this in again same concept parallel to the stick and we're going to take the move the collinator remove the sensor and the cotton roll and we'll show you what we got for that Here is your final result with the cotton roll and you can see we got the apices of 31 and 30 which is what we're looking for. We got behind number 31 and we have a very nice image.

I'm now going to show you how to get a difficult wisdom tooth. We can now adjust the sensor position. Instead of being in the regular position like so, where it's sitting in the holder like this, we take it out and we flip it. So now the square end here is going to be towards the posterior. When you put this in the same way you do, it's just you don't have to push it as far back as normal.

So again, the key is finger is going to be on here in the mouth. Have them close a little bit and as you press you have them close. Keep closing and close all the way down. So now you have it put it back as far into their mouth but the sensor is extended out towards that wisdom tooth. Again, same concept, parallel to the stick against the cheek and we're going to go ahead and see how we do.

Remove the collimator, remove the sensor and we'll go ahead and see how the image appears. Here is the image we took with the sensor, the rectangular side of the sensor, extended from the posterior holder, and as you can see, we are in the wisdom-tooth space very cleanly and we even got that and beyond.

I want to show you how you can get in a smaller mouth or a child a bitewing without using the red bitewing holder if necessary on a more difficult patient. Again, put the sensor on the endo holder like so and we're just going to slide this in like you would a regular bitewing X-ray and you have them bite on the stick like so. They can hold it also if they'd like and then you just line up like you would for any bitewing when you're using the bisecting technique and I'm going to show you what it looks like.

Go ahead and remove that and you can see that was very easy for her. And here are the two images we captured, one you can see how far back you can get, and then one more forward and you could even go more forward if you chose to.

I'm going to now show you our occlusal holder for children to take the occlusal shots and protect the sensor. Sensor rounded or comfort end, distal end goes, slides right into the sensor and it doesn't have to go in all the way. That way you have a handle to get it out like so, you're going to now place it just as you would any other occlusal, have the patient bite together and again, you got it coming out of a pretty steep angle, bisecting technique and we'll show you what that looks like. And then you have them removed.
