Implants, partials, Another case

Thread rating:  |
quattrocchi - 24 Jan 2005 06:00 GMT I've been watching the various discussions about what's possible with interest. I was interested in James' recent thread 'Implants or partials, or both?' and emboldened to also show my horrific xray. I've grown up in a small town area where the norm was full dentures by age 18. Sounds amazing nowadays, but that was the way then. I guess they thought it was some type of modern technological advance. Anyway my teeth were well filled and several pulled by the time I was 20, with triple abcesses in the bottom front. However I was convinced that the best action was whatever allowed me to retain my own teeth.
Now in my mid-50s I have quite a wavy bone line from the gaps, over-eruptions, teeth reconstructed to the limit, and a few root fillings. The over-erupted upper molar is painful to cold/hot, so it's time to try prosthodontics.
I had the molds done in December and am about to be called into my fixed prosthodontic clinic. I asked for a variety of options at this point, with a similar variety of costings. I can't afford a mouthful of work.
I hope for a return to chewing well on both sides and that the variety of options will extend to what's available worldwide.
Here's the state of my teeth www.adam.co.nz/xray/jpg As was pointed out to me there will be some bone and gum reconstruction needed in places, esp where there are missing teeth.
Any thoughts here on what I could expect in the way of options?
Thanks

It's amazing how a slash instead of a dot can make all the difference!
Anyway, the panoramic film posted is difficult to read, due in part to the severe half-toning of the image. Try resetting the scanner to eliminate the "newspaper half-tone" effect and see if that's any better.

A set of periapicals would be better yet, as they show more detail than a single panoramic film, but this film gives a general idea.
It looks like a large crown & bridge case, which is not uncommon. Assuming the periodonal condition can be improved and controlled, three fixed bridges ought to replace the missing teeth, although implants there -- expecially in the larger edentulous areas -- are usually preferable to long-span bridges. So one fixed bridge and several implants is another alternative.
A couple of the lower molars seem to have restorations almost into the furcations, so that would take close examination to determine whether crowns or endo would be needed.
So it might involve bridges, implants, perio treatment, and a few crowns and possible endodontics. Is that about what you have planned? Regards, - dentaldoc

Is that about what you have planned? I've yet to see my prosthodontic man here, who is as we speak (I hope) making up from the castings he took of my mouth some choices of treatment. I'd like the choice of costings, though I guess cost equates to durability. My prosthodontic man also tells me that as a result of the bruxia-induced wavy dental line I have bone and gum decline in some parts and overgrowth in other parts. 'Periodonal condition'? So he's getting me to see a bone person and a gum person (excuse the lo-tech terms) for their evuations as to correcting this. Note that overerupted tooth. It's temperature sensitive now. what's possible there?

Yes... ;) Might I assume then that the synchronous occlusion with two acrylic partials is a temporary solution? Sounds cheapest! How temporay? So what's the reason for this two-part treatment? Are there things that will become eveident after fitting the partials, and/or is a settling down period advised?

So, basically, you'd have an almost 0-degree cuspid rise with long centric stops... toward the distal to allow free protrusion, I would think...
If I understand this correctly, there are any number of my patients who would benefit from it.
One thing I read in an old 'Dental Clinics of North America' on Prosthodontics: don't ignore the centric stop in the central fossa. If it is weak, the occlusion is unstable and the tooth will move, since all occlusion is now on inclines, usually angled in the same direction.
So, I can see why a long centric in the central fossa or groove would be important.

You have the right idea
>>> Then, provide 2-3mm long centric towards the distal. > > Hmm. Is this 2-3mm forward movement from the relaxed position? 2-3 mm Freedom to move backward (if your jaw is capable of doing so after relaxation of muscles). An additional 2-3 mm of forward movement is the "normal" concept of Long Centric.
>>> Then, give it some time to see if the patient has any occlusal disease. > [quoted text clipped - 5 lines] > and if they're long then the force is reduced? > What's a cuspid rise? the curve of spee? If the contacts are in "long centric" the teeth have freedom to slide forward and backward.
Cuspid rise is the functional occlusal scheme we are taught to persue in dental school. I check every new patient to see if they have this or not. Only about one person in twenty really has cuspid rise. In cuspid rise cases, the cuspids are the only teeth touching as the mandible slides side to side.
Curve of Spee relates to the curve to the plane of occlusion. Imagine a piece of cardborad held between the teeth by biting on it. This is the plane of occlusion. The curve of Spee is a specific curve along this plane.

Dr Steve - 03 Feb 2005 12:56 GMT I think two things stick out in the Horger concept of occlusal synchronization. One is the 2-3 mm of distal freedom of movement, (this way, you don't have to find CR, you just allow the mandible to go there if it wants to). The other is the "feel" of rubbing two models together in your hands and finding interferences by touch.

I can't even remember all of the cases that I have done where the teeth were set (dentures) with the patient in CO and they return functioning in CO but going to CR in a rest position. Would register the bite in CR, Remount case and adjust the occlusion to accomodate a smooth transition from CO to CR.
Is this what Otto refers to?

No, you can have inclines on your teeth. The slopes have to all be in harmony with each other. As you slide up (or down) one slope, you don't want to click over something else.

That is from the school of occluSION, not the school of occluDING. If the patient habituates in a lateral protrusive bracing position, having good centric stops do not stabilize the occlusion. If the patient has an isometric clench on the anterior teeth, the anterior splay outwards. Eliminating parafunctional activity is what stabilizes the occlusion.
> So, I can see why a long centric in the central fossa or groove would > be important. The long centric is freedom towards the distal to allow the mandible to position itself more distally, (not for protrusive movements) if it wants to find CR. The key is not to create any interferences getting to CR. Then, if the patient never goes to that elusive and strange RUM joint position, you at least know there is not occlusal interference preventing it.
Take your next set of *un-articulated* stone models of a mouth with most of its teeth in place. Hold the models in your hands with the teeth in CO and the plane of occlusion at a right angle to your body and to the floor. Now, softly rub the models in a circular motion. You will feel the interferences with your hands (if you are gentle enough). Outline the spots in red, remove a tiny bit of stone, and check again. You should end up with a series of red circles around cuspal projections which interfere with synchronous jaw movements. You can then use these marks as references as far as where to adjust in the mouth (if there are not too many). If a lot of adjustments was necessary on the models, this should probably done in stages with new models each time.
I have to run back into the operatory, let me know if this makes more sense.
