Podcast 182 Dwight Jennings A Live Look at Bite Realignment How TMJ Impedes Performance

Dwight Jennings: This is polyvinyl siloxane, it’s a silicone epoxy that sets up in about 15 seconds. This is a much higher accuracy at figuring out how teeth come together than either carbon paper or wax, or anything else. Dave: Okay. Dwight Jennings: Bite on your back teeth; stay closed. Let’s see that nice endonend bite. Good. Open for me there. Dave: All right, hold it up for the camera Dwight Jennings: Then we hold this up to the light and it tells how everything’s Dwight Jennings: How everything’s touching. This is like a pressure gauge. Right there? Speaker 3: Yeah, perfect, thanks. Dwight Jennings: It shows us in thousandths.

Of an inch how everything’s touching. Dave: We can see more light coming through parts, that’s where my teeth are hitting right now? Dwight Jennings: Right. Dave: My jaw is misaligned because I’ve been sleeping without the right bite guard for a while. Dwight Jennings: Yeah, so you you’ve got some outside . Normal teeth should meet like this, you’re upper tooth should hang a half tooth out over your bottom tooth and so you should only have peak to valley and peak valley and not on the inclines. Some of these we were showing some inclines in the back but we’ve come together pretty good.

In the front. We look like we’re maybe just hitting maybe just a speck heavy on your right front tooth, but pretty good. Let me look at the picture; bite, close for me now, let’s see how everything’s growing here. We’ve grown, we’re getting down pretty close there and if we were closer and we were just in that night piece more often on you, those teeth would be able to grow in quicker and Dave: Okay. Dwight Jennings: They stayed quite stable there, everything’s pretty good; just one little speck on the outside and a little speck on the front. Dave: Invisalign just came out with new thing.

That allows you to pull teeth out to make them grow faster of about a millimeter every four to six weeks. Have you played with yet to first growth? Dwight Jennings: I haven’t; I’ll have to look at that. The problem with most Invisalign treatment is that they don’t grow the back teeth taller. You could take somebody who has crooked lower front teeth, and you start straightening those front teeth, it forces your jaw backwards on you unless you’re putting vertical in the case. I have a couple really severe cases, I have a 35yearold male who developed hyperacousis and became totally disabled over Invisalign. Then I have another lady that we just started.

On that developed severe oralmandibular dystonia; she lost her ability to talk at about six months into Invisalign therapy. Dave: What’s going on there? Is a focus on cosmetics, not function. I certainly know one guy who’s using Invisalign for neuromuscular dentistry. I think it’s not that Invisalign is good or bad; it’s that if you use it to just make things pretty, well, we you might lose function. If you use it to make things functional, it seems like a pretty neat tech. I was thinking of using it, I wanted to talk you first to help my back teeth grow, because they don’t grow very quickly. Basically, I don’t know how exactly it works, but it’s only been out for three months, so I’m interested.

Dwight Jennings: They’re most likely to be putting buttons on those teeth and they just stimulate the Dave: They just keep pulling the tooth up a little bit, so you one or two teeth at a time on each side; but the growth rate’s very fast which is cool. Dwight Jennings: Teeth, it takes five times as much force to intrude a tooth as it does to extruded tooth; so teeth, you can pull them up pretty easily. Dave: Oh, cool. I think I’m going to do that because I don’t know if the camera can catch this, but if you look in mouth I have these big caps on my back teeth but the ones next to it aren’t there, so see that?.

Dwight Jennings: Now we’re going to adjust that back crown. Dave: You’re going to grind down the high points? Dwight Jennings: Yep, so you should either be hitting on this little ridge through here or this valley through here but not out over . If you hit on this ridge properly, there’s equal amount of light on this side and this side of that line, and this one’s heavy on the outside. Dave: I also feel like my front teeth are hitting a little bit more than they use to, like the pressure there is higher. Dwight Jennings: Yep. Dave: You going to fix that?.
