This is a demonstration video for temporary crown construction using self cured acrylic resin for dental students, presented by Crown and bridge department, Faculty of dental medicine, Alazhar University, Cairo - Egypt. 2013

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.
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.
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)
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.
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.
+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.
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?
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.
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.
On today’s market there are many products with such orientation, but most popular is advertised brand Viagra tablets.
Appropriate tests show a positive result, which is about thirty per cent of all subjects. But here it is necessary to take into account the psychological aspect, since a positive result will not be at the unwillingness of sexual intimacy.
Cialis is yet another pill for impotence. Cialis and Viagra can be called brothers. Effectiveness of tablet lasts for about 30 hours. Cialis action when compared to Viagra, is faster. Cialis acts on the walls of blood vessels, preventing them from relaxing, thanks to the influence of substances that trigger it.
Cialis is admissible to the use of alcoholic beverages. The drug takes effect quickly, and the action is very long. What is best Cialis Viagra or Levitra
