Medical Forum / General / Dentistry / March 2008Crown in Pristine Condition-- Abutment fractured...?
Is is possible that #8 tooth after prepped and fitted with a crown can "fracture" due to "acute and chronic trauma" when chewing caused by missing 28-31? while the 18-month crown itself remains in pristine condition? Wouldn't decay be the more probable reason why abutment #8 fractured? ric > Is is possible that #8 tooth after prepped and fitted with a crown can > "fracture" due to "acute and chronic trauma" when chewing caused by > missing 28-31? yes >while the 18-month crown itself remains in pristine > condition? yes > Wouldn't decay be the more probable reason why abutment #8 fractured?

Why guess, or do you not trust your dentist? If there's decay, it will be visible now. Steve It ain't because 28-31 are missing. Parafunction. Bridge abutment ? Endo ?

Are 28-31 missing or not ? Yes, they are missing and it's my understanding that if "chronic trauma" caused the fracture of #8, the missing 28-31 are the culprits. Which is to say, the missing teeth caused an incorrect bite. Of course the problem with this is that should have been seen before the crown was placed, no? ric Missing teeth do not cause an 'incorrect bite'. And it isn't the bite, it's what is being done with it. IOWs, the muscles, ligaments, tendons, and bone can beat up anything. Yes, missing teeth can lead to increased forces on the remaining teeth, but the bottom line is that you are probably clenching. Parafunction is the term. Steve Fawks >>Wait a minute.

Disagree, parafunction is the "culprit". >Which is to say, the missing teeth caused an incorrect bite.

If you are missing #28-31 then you may be doing an inordinate amount of chewing on your front teeth to compensate for not being able to chew on your posterior (back) right side. Additionally, when an anterior (front) tooth that has a crown fractures, I usually look for the possibility that the tooth was in need of endodontic (root canal) treatment. If it did need endo treatment the tooth becomes brittle and can fracture more readily than a vital (live) tooth could. Possibly the combination of both situations, missing some back teeth and needing endo treatment on #8 precipitated the fracture. Your dentist may be able to put the crown back with a post and build- up. God luck.

Then let me put this to you and Steve Fawks: should I have been informed before the crown was placed on #8, that missing #28-31 would compromise the integrity of the crown? ricland no I suspect you have been told enough times over the years that the back teeth should be replaced. You chose not to do so. Don't blame the consequences on someone else. > On Mar 19, 7:07 pm, gary.a...@gmail.com wrote: >> [quoted text clipped - 30 lines] > > ricland > no > [quoted text clipped - 36 lines] > > > ricland You assume a great deal. I wasn't never told the mixing teeth compromised the integrity of a new crown on #8.

What is so amazing about this discussion is that not so many years ago, it is likely that no one posting here or advising you there would have uttered the words "parafunctional habits". As for the "habit" of it all ... WB, does that not suggest that it is within the *will power* of the individual to change the habit/s??? It does seem that way given your chosen words. But is it more so that the person would need to utilize something that alters or in some way interupts that habit/s ... for the person with the habits??? I am asking this because as some/many of us might agree, the term "parafunctional habit" is not yet a household expression. And when the everyday-Joe hears this expression they are likely to be asking themselves, *** "WHAT??? What is a parafunctional habit?????" ***** Obviously, this might need a thread of its own. ;-) Webby >As for the "habit" of it all ...

Have many habits myself, blinking, swallowing, breathing... all of which are conciously alterable, but persist nonetheless. I saw nothing in the quoted text that I had written, but the fact that #28-31 were missing is not the reason you had problems with crowning #8 *as the sole reason or likely reason*. The potential problem that *might* have been identifiable is that your teeth show damage from parafunctional activity. Treating the parafunction in addition to the crown might have avoided this altogether. However, I inform many patients of their parafunctional problems, and they don't want to listen. They especially don't want to bother wearing even a simple NTI device to control the problem. They do not understand the severity of the problem, and just want to wait and see how every thing goes. The next cracked tooth, fractured cusp, or broken crown comes along and most of them finally get the message. Unfortunately, it is often many hundreds of dollars and sometimes lost teeth, before the 'awakening'.
