I recently, had a zirconia dental implant put in. My dentist wanted to use "ArgenZ esthetic zirconia" for the crown. I got the ingredients on this and I guess it is acceptable. The company was unwilling to give me the MSDS on the product however. He wanted to use a glass ionomer cement which I said was unacceptable due to it being Fluoride releasing. So now he wants to use Zinc Phosphate cement. I've been researching these and the powder part is relatively benign however the liquid part not so much. Some of them also have fluoride. I just wonder if anyone new of a zinc phosphate cement that was relatively harmless. Every company seems to have different ingredients. I spent countless hours trying to find the best one with little to no progress. If someone has already been through this or knows of a good cement PLEASE let me know. Thank you!
