Difference between PFM and Full Ceramic dental crown

By steve 2/25/2011 8:13:33 PM
So I chipped my #13 pre molar the other day and the dentist said that a crown is necessary. HE gave me the regular options of Porcelain fused to metal or gold, plus a third option of an all Ceramic/Porcelain crown. I believe I had the latter on a molar that cracked on me 2 years after having it placed (another dentist) after eating a cookie. My present Dentist says that one of the main advantages of all ceramic\porcelain is that it is bonded to the tooth as opposed to cemented like a PFM. It is also less likely to come loose from sticky foods like caramel. He also said that the data from the 10 year study is coming in for the all Porcelain crowns and that it is favorable.(I am not finding too much info on my own regarding this) The cost difference is $150 more for the all Porcelain over the PFM. I am not so concerned about the price as I am about functionality and longevity

You can go for either but the chaces of fracture of all ceramic crowns in back teeth are more as compared to PFM. Mostly the full ceramic crowns are initially recommended for front teeth as they are very aesthetic. They can reproduce the natural look of the tooth like tranlucency etc which cannot be reproduced by PFM as in PFM there is metal inside. So that is why PFM are recommended in back teeth as compared to full ceramic. #13 tooth is premolar and is not much used for mastication of food, so you can go for full ceramic crown also.

Thanks for the quick response. The ceramic crown he suggested is a Cerc crown. He said it is made out of a single block of ceramic/porcelain. How does that compare to a crown that is not made via the Cerc method?. I also have a molar missing right next to that tooth. In the future I would like to replace the missing tooth with an implant but how soon I am not sure. Thanks, Steve Z

Basically the difference between the Cerc crown and the other all ceramic crown is in the technique of making it. CERC crowns can be made in dental office and is an advanced technique of crown making which only few dentists have. It does have good strength, quality and uniformity and is ready in minutes. For missing molar you can definately go for implant at later date.
