frank jerome has his beliefs, but many dentists do not feel the way he does about indirect vs direct fillings.  i was taught that onlays/inlays are difficult to get a good seal on, have a weak spot and break easier than composites or crowns.  jerome's ideas are quite controversial.  yes, porcelain and metal do not like to stick to teeth.  composites stick very well.  so, more tooth structure has to be removed for them.  that is why it is best to do them on larger cavities where there is already more structure gone.  today's composites do not shrink like those in the past, especially diamondlite and diamondcrown.  none of the filling companies disclose the full list of their ingredients due to patent rights, except for Hal Huggins does have a full list.  He is the ony one who was ableto obtain it.  Walter Clifford has a partial list.  dental companies do not want anyone copying their products. 

The Diamond range is designed with a unique and patented medical grade resin PEX that is proven highly biocompatible in numerous tests. The ceramic glass fillers used are of the highest purity so that the usual residual metals have been eliminated through an exacting manufacturing process. The results are dental materials with superior biological and physico-mechanical properties.

cerec is a chairside cad/cam.  it can be done in the office or in a lab.  cerec is the procedure, but also refers to the dental blocks crowns/inalys/veneers are made out of.  other materials can be used.  i was giving a general answer.  DRM does not disclose it's procedure for burning off metals.  It is another guarded secret.  You have to understand that companies that make dental materials guard their patents and manufacturing techniques well.  They always have.  It is a very competitive market.  This is all the info about it:

The CEREC team at Sirona is fortunate to have partnered with three dental materials manufacturers. Vita manufactures CEREC Blocs by Sirona and VITABLOCS® Mark II for CEREC^®.  These blocks are made of feldspathic porcelain. Ivoclar-Vivadent produces Empress CAD^® leucite-reinforced porcelain blocks. 3M™ ESPE™ makes the Paradigm™ MZ100 composite block for CEREC. Once again, Sirona has put to use our philosophy of the "Synergy of the Best" to bring to you CEREC by Sirona and materials by these fine manufacturers.
