PFM Crown Warranty/Guarantee? And Ratio Metal to Porcelain?

Hello Doctors, I have two questions. I need a crown on a molar (that is noticeable when I smile). I would like to go with porcelain fused to high noble metal. I would first like to know what guarantee/warranty I should get, and if I should get it in writing. I would take the best care of my tooth possible. An excellent dentist in Mexico can give me a 5 year written guarantee. But, I would rather stay in the US. Also, what is the best percentage of metal to porcelain? Is 30-40% metal standard?

PFM Crown Warranty/Guarantee? And Ratio Metal to Porcelain?

Every patient wants a long-term, long-lasting result from their dental care. As a dentist, I want it to last a really long time for you as well. After more than twenty years in practice here's how I handle it. We have no specific written warranty. There are MANY factors that can affect how long it lasts. However, I stand behind my work and want my patients to be happy. IF you had one of those very rare circumstances that you damaged some of my dental work, if it was the first year or two... more

Ratio of metal in crown?

First I don't like the word guaranteed in Medicine but the point is most dentist will redo or replace treatment that was recommended as a goodwill gester... the reason if you don't take care of your health the problem is yours not necessarily ours!!! The second question should be what type of metal is being used high noble semiprecious and or base metal that determines the ratio of precious metal to non precious metal. In the US all dentist submit to dental ins. companies and must indicate... more

Crown Guarantee

Can you really enforce the Mexican guarantee? I would have my doubts. Crowns should not be made with any metal any more. Good crowns are 100% ceramic either zirconia or dilithium silicate. THey are absolutely proven to have the strength to endure in the posterior. They don't have the potential for allergic reaction to a base metal undercasting and are more esthetic. I would advise you use a US dentist who guarantees his work an uses all-porcelain crowns. more

PFM crown warranty??

Firstly, medical procedures are never guaranteed. One does not walk into surgery asking for a gurantee. Dental medicine should be seen the same way. A restoration of a severely traumatized tooth that has had history of decay, fracture and multiple restorations has a certain success rate when treated with a full coverage restoration, also known as a crown. The average longevity of a PFM crown restoration is 90% at 10 years. If you make sure to keep hygiene... more

I asked this question because there can be dentist error. One dentist, whose name I can't find unfortunately, responded to someone who asked how long crowns are expected to last. He commented, "Did the dentist use accurate impressions and send the case to a competent lab Technician? Was the Crown inserted under dry conditions with well mixed and dispensed cements?" I think my concerns are valid.
