Orangina's Dentition: Part Duos
You may or may not recall that a few days ago I posted in GD that I elucidated his lower dentition’s issues.

Today, MS Now showed this photo:
This is often what happens when an individual loses his or her back teeth: they lose a position of the jaw called centric occlusion. Centric occlusion or CO is, and hopefully you can try this yourself, you bite down and your teeth fit together maximally and optimally for you. There may be all kinds of missing or fractured teeth, malposition, or other issues such as crossbite but you have adapted to these issues and you are “doing your best” automatically to maximize your contact between your jaws.
Now this is MUCH more complex than I’m outlining here, whole books have been written on this subject, but this particular case is not uninteresting. As I outlined in my previous post, it appears convincingly that he lost on both sides his molar teeth in their entirety on the lower arch as well as his second premolars leaving only his first premolarswhich anatomically are not really supportive teeth: they’re considered transitional, that’s one of the reasons that they are extracted in crowded orthodontic cases.
Thus he has no bite support or reliable contact points which are comfortably definitive and that is why he’s shifting his jaw forward as he is in the photo, he’s involuntarily looking for comfort and cannot find it. The movements become exaggerated and subconscious, like a twitch.
The other thing that it does is that it makes the individual look very old very quickly, we used to call it the Andy Gump look. People in their late 50’s can look to be in their 80’s. It is one of the factors that has aged him in the last year or two.
I could go on and on for hours but I’ll spare you. I will leave you with a photo of Andy Gump, so you have the idea. What happens is that the chin is too close to the upper face/nose and the chin can either become prominent as with you know who, or if receded, it disappears as it appears in this drawing.
More to come…
