in my opinion, it is diamondcrown (a crown product that can be used for fillings) or diamondlite. if you pick diamondcrown, be sure the dentist is experienced in it, because it takes a bit more skill. also, go to a dentist who does not drill the fillings, but cuts them out, to minimize mercury exposure.

No, i don't know what it is. Germany is a country that is very picky about what it puts on the market. They have good controls and laws in place. I know a Dentist who uses only German materials. But, when I looked up some of those one time, it had some of the bad ingredients that you don't want in dental materials. So, no matter where the product is from, no matter what company makes it, one should look over the MSDS of the product and compare it against known toxic ingredients.
There is HEMA in DiamondBond, which is considered a compound with high risk of causing allergy, but all adhesives contain methacrylate derivatives. I believe DiamondCrown are the best fillings we have to date. In the future, Zirconium fillings might be a better choice as far as durability, but they are not available yet and they will use the same adhesives most likely that are used now. The zirconium oxicde crowns and bridges are supposed to be highly compatible. They are new on the market. Some of them are made in Germany. ZrO2 by itself does appear very compatible, but it will depend some on the other products used with it. I know 3M is using propylene glycol in their preparation. If you find the name of the product, I might be able to get the MSDS.
Myself I do not like hygienists and go to dentists who do not have them. I think they can cause a lot of damage to teeth.

Cerec is an indirect all ceramic crown, onlay, or veneer. Most people get direct composite fillings, which are better for small and medium cavities, as they stick to teeth very well. Ceramics (porcelain) do not stick as well and more tooth structure must be missing or drilled to create a hole that will lend the best adhesion.
The blocks of ceramic (porcelain), as well as direct composite materials do have metals. Diamond nearly all of the metals burn off during processing. The Diamond line, the ceramic glass fillers used are of the highest purity so that the usual residual metals have been eliminated through an exacting manufacturing process. But, adhesives always have at least one or more toxic ingredients. It is best to use one that has the least.
Degussa made by Dentsply is also an indirect ceramic onlay or crown. There are many products in this line. Here is an example of part of an MSDS for Ceramco 3. This does not include the adhesive.

DiamondLite fillings have Dimethacrylate esters listed on their MSDS. DiamondBond contains HEMA, a methacrylate, but all adhesives contain methacrylate derivatives. DiamondBond, appears to be the least toxic of all the bonding materials.
You can use this as a reference for materials that are least and most desirable:

Biocompatibility reports are individual. As you can see, there are many ingredients in Cerec that could cause a reaction in some people. There are common dental products that most people are compatible with. The Diamond line is one of the best as far as biocompatibility with the general public.
Hal Huggins invented the original serum biocompatibility test. He and Walter once worked together. They had a falling out and Clifford went off on his own. He made his own test based on the same blood test, just that he was only able to obtain partial disclosure from the dental product companies as to the ingredients. Hal had full disclosure, but they only were willing to give it to one person. Has since sold his test to Dr. Levy whom I had the pleasure of meeting a few years ago in L.A. I spoke with Walter a few years ago and also spoke with Scientific Health Solutions (Hal's test) and both of them confirmed that the SHS has full disclosure but the Clifford test does not. Walter is a nice person and he told me that he feels his test is adequate. But, for my money, I went with the SHS test. Biologic Dentists use either of those 2 tests if you have one done.

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.
huggins has full disclosure and walter was only given partial, because companies just don't give out that info and hal was very lucky to have obtained an agreement with them. scientific health solutions, walter clifford, hal and my dentist were the ones who told me.
to learn about PEX, read the DRM site or write or call the company. i read an interview with the inventor on their site that their composite fillings can last up to 22 years.
most dentists do not do inlays/onlays or crowns unless substantial tooth structure is gone; they prefer composites for most fillings. when the fillings are bigger, sadly, they prefer mercury fillings unless they have to do a crown.
i have never had a white filling shrink and fracture a tooth, in fact mercury is much more apt to do that. ,y dentist doesn't like them for several reasons and one is that he says they have a weak spot and can break. he prefers crowns.
most dentists do crowns before onlays/inlays because they they feel they are stronger. but, if i had a choice, i would try onlays/inlays before crowns on my teeth if at all possible. often times the dentist finds himself with a tooth that he feels is too big for a composite or an inlay/onlay and has to go with a crown.
i am aware of jerome's ideas, but he is controversial and i was taught differently. most dentists charge the same or close to the same for inlays/onlays as they do for crowns. many dentists simply have a harder time fitting indirect composites. i have met a couple people who had crowns for 50 years, so they do not always fail. one thing, though, they should be replaced every 10 years is what a dentist told me. that probably helps their lifespan.
i am not interested in a debate.
1. most manufacturers do not tell the full composition, or amounts of them, in their fillings. the only two i am aware of who possess such info, who are not the manufacturer, is clifford and huggins (huggins sold the test to dr levy a few yrs back). clifford's is not full disclosure, but partial. neither of them are allowed to disclose the compostions, as they signed an agreement. if you want to hear this info for yourself, call walter and/or scientific health solutions. that is how i found out, and from my dentist. they told me about 6 yrs ago.
2. i post info and answer questions. i do not disagree with people personally
3. we all have opinions and the reason debate rooms were created was for those who wish to argue their points. i do not wish to argue mine, just take it for what it's worth. post your side and i'll post mine. we can all learn from each other.
Update: 3M will give full disclosure if you sign a non-disclosure form.
that is what was told to me, that all filling manufacturers do not disclose the full ingredients. hal, i trust only because he is known as the father of the amalgam removal movement and i would not be alive if not for him and would have never known mercury was in fillings. he wrote the first book on it in the US and has studied it for 30 yrs or more.
update, 3M corp will disclose full ingredients if you are willing to sign a non-disclosure form. there may be others that do this for you, as well, but most do not. in the US, only hazardous ingredients are required to be disclosed.
