My temporary crown came off and I don't get my permanent for a week. Is this a big deal?

i prefer not to remove the temporary ... it had mechanical retention ... just remove excess

So im wearing a temp crown right now that feels too big on the inside, like it needed to be filed more because its not aligning on the inside. So my concern is that the crown will be exactly like this temp one? Because if it is, we gon have some issues.

Hello, friends. Question: Why is dentistry not filling teeth with permeable restorations? The dentin is porous. The enamel is "permeable" - in fact that “95% mineral” is by weight, not by volume. By volume, dental enamel is only 50% mineral. The other 50% is amalogenin and water. When you look closely, the enamel is a sieve, designed to allow dentinal fluid, with all those wonderful minerals, to flow freely outward, driving out acids and other materials, remineralizing damaged areas. In fact, when a carie develops, the gaps open even further. Natural body defense. To dam this wonderful system with a impermeable porcelain toilet bowl of amalgam, impervious composite, or a crown makes no sense. Motion is life - stillness is death. Impermeable dental work creates stagnant pools of dentinal fluids in a dark, warm place - perfect environment for anaerobic microbes to proliferate. Whether that is the corporate plan is arguable, but the toxic effect is a fact. So where are the permeable restorative materials? “The presence of bacteria located at the interface between composite materials and dental tissues may be important (Hansel et al. 1998). EGDMA ethylene glycol dimethacrylate and TEGDMA tri-ethylene glycol dimethacrylate promote the proliferation of cariogenic microorganisms such as Lactobacillus acidophilus and Streptococcus sobrinus; TEGDMA stimulates the growth of S mutans and S salivarius in a pH dependent manner (Khalichi et al. 2004). This provides one explanation for caries that develop beneath restorations of resin-containing materials. In addition, bacterial exotoxins have harmful effects on pulp cells after diffusion throughout dentine tubules.” http://copublications.greenfacts.org/en/dental-amalgam/l-3/5-health-effects-alternative-materials.htm After hours on the internet, I am having no success in finding permeable dental restoration materials. Dentistry is somehow fixated on putting toilet bowl procelain caps (amalgam, composites, crowns) over the dentin. The preventative and restorative outward flow of dentinal fluids through the amelogenin rich enamel matrix is totally ignored, it seems. Dentistry’s current methodology seems guaranteed to create stagnant pools of nutrient rich fluids in dark, warm, oxygen deficient places. That does not inspire much confidence. I need 3 substantial fillings. Thanks for all you do.

If you read this much, you should find out information about some dental infiltrating materials ( ICON, for example) . Try searching this word you will find some interesting spots.

My dentist could do with watching this video. He took that putty stuff you used to make a temporary crown and by hand just put it around the filling then left it to set. leaving a bulky shape around the tooth that needs to have the crown fitted. 😑

I swallowed one, just now,  what now?? all this on ad off of the sametemp is pissing me off. why proscratinate putting in the real crown???? ive been waiting for months with a temp that fall off everyweek making me look like a scumbag to new clients for several days before my next appt. haven't had a decient whole meal in moths either. I'm strting to lose weight.   very hungry. cant eat anything. no way to bite or chew.  why doe sthis take so long to do?

+Edward Dergosits 10 days???LOL!!! today was my 25th visit, every 2 weeks for over a year, and today they finally made the damn core for the new crown and put new temps on. as 2 separate teeth not the lego block I had for over a year now. beveled both roots bases cleaned them up  and now in 3 weeks I go back and the job will supposedly be finished. yeah right. somehow I don't believe them. then they can finally issue my dentures after over a year zip out a few cavitites and I'm never ever going to a dentist again unless its to pull something . fuck this crap anymore. todays visit did not tickle either. I have permanent damage to my upper right lip that never came out of anesthiesia from a cleaning I didn't even want almost 2 years ago(on the tooth I lost anyway which is the crown I'm awaiting)(the statue of limitations here for malpractice) the k9 crown I went in on emergency to be re cemented in oct of 2015 STILL has not been permanantly cemented back!!!   and every visit for the past year has been taking off, putting back on, these damn temps. my gums are so sore now. haven't enjoyed a holiday meal in 2 years. Christmas gifts like choclate or caramel popcorn had to be given away. (mostly what I get)

More than 10 days is way too long to be appointed for delivery of the final restoration. Where do you live?

Still wonder this about dental general so eye doctor spray doesn't hurt anymore. why not have soundless dental drill so paient can''t hear the whirring.
liamnaruto (2 года назад)
Dental community how about you find a paste that doesn't taste like butt. a person with bad teeth.

at my dental school 1. it is illegal to use a high speed at all during crown prep 2. it is illegal to take impression before hand. you have to make a ball and then carve it all free hand.
thanh phan (2 года назад)
thank you.,in my place, temporary crown is made by the dental laboratory technicians, use a diagnostic cast to construct it
RIFAT ARA FATEMA (3 года назад)
very helpful.thanks
Ianreed2288 (3 года назад)
I don't like this technique for a few reasons.  First monomer and polymer should not be used directly in the patients mouth.  The exothermic temp can be too high.  Additionally it contains BPA - not good for the clinician or the patient.  There are products out there that are safer and do a better job.
Azhar FPD (2 года назад)
Well, we do use a variety of materials for the construction of tooth provisional restorations. However, this video aims at demonstrating a simple method on how to use this material for the construction of teeth provisional restorations. This material is challenging to some of our students, so, the aim of this video is to explain it clearly and simply to them.
Cosmicat (2 года назад)
I do think the same way. Have you tried revotek? I'm tempeted to try it myself.
Azhar FPD (3 года назад)
+Ianreed2288 I do agree with you. however you should take in consideration that this technique is described primarily for our collage students. and due to financial causes we still learn then them this technique. but again i agree with you that the other methods of making temporary crowns are more safe, aesthetic and and more time saving.

Never ever use crown can cause cancer

How long a temporary crown generally last ? what are the precaution we need to take after having temp crown ?
Harsha Madhavareddy (3 года назад)
aerotor without water spray??? get back to basics
Azhar FPD (3 года назад)
+Harsha Madhavareddy it's just demo on non-living model. there is no basics about using water spray considering this point.
Manav Kalra (3 года назад)
one problem with this technique is that... we cannot evaluate the re seating of the impression onto the tooth surface. especially in the mouth. Having the whole impression and the full arch tray will make it more difficult.Also for a single tooth temp. full arch is not required. Do you guys agree?
Gokul archun (9 месяцев назад)
Manav Kalra sir..can we use impression compound instead???And i feel better to use at teeth of interest only!!

I wish to know the manufacturer of temporary crown material acrylic base, powder+ liquid
MsJess619 (3 года назад)
open mesial contact and the bite looks very high...
Azhar FPD (3 года назад)
+MsJess619 It is just a  model. But in the live cases we must adjust the occlusal contacts in the centric and the eccentric movements.

Thanks for the video. What type of cement do you recommend to use with a temp crown?
Ck W (3 года назад)
try dycal. simple and with analgesic propeties esp on a freshly trimmed tooth
rhBOSS (4 года назад)
You shouldn't use acrylic resins in the mouth due to exotermic setting reaction. Take an impression, cast a model of prepared teeth and make your temporaries on that model.
Ck W (3 года назад)
+frank the tank so true. for someone without experience with it, the aftermath is gona be catastrophic.
frank the tank (4 года назад)
You're right. And what is not shown is how hard it is to remove the crown when you leave it on the tooth until the reaction is completed. 
טל מרום (4 года назад)
Thank you for the video. But you don't have a mesial contact and you can see the palatinal finish line. I think you should have fixed that.
Berninman (4 года назад)
I agree

Educating Patient is one of the very important part of successful practice, But mostly it find that educating patient is one of the delay obstacle in dental practice. As a dentist I got some help through such organization : http://dental.peasonline.com/patient-education/ must visit at least once.
John Highsmith DDS (4 года назад)
This works but takes WAY too much time. Use a VPS bite registration material in a triple tray for the impression before preparation. One minute maximum time taken. Also use a BIS-GMA material in a double barrel syringe like Integrity or Luxatemp for the temporary crown. It doesn't shrink like powder liquid materials and looks better. This whole process shouldn't take more than 5 minutes.
