No way, you will be pulling your hair out trying to press and devest .2mm veneers. if you read the Ivoclar instructions on all of their pressed materials minimum thickness is 0.8mm for pressing. However, lithium disilicat does fill a mold more easily than other press materials. I don't think we press anything less than 0.5mm. This is part of the reason you need to get a good fee. After pressing there is considerable finishing to thin the veneers and get the shape correct. In addition, the majority of patients are not good candidates for no prep veneers as this will result in over contoured final results.
Lumineers, the company, has been great with marketing this very simple proceedure to both dentist and the public. The dentists are sold on just taking an impression and the patiens are sold on not having there teeth ground down. Dentist go to a Lumineer weekend programs and pay big bucks up front for future lab work produced by Lumineer. You've got to love the business model. But, in reality, it's not a good Rx plan for most.
Anyone else have experience pressing very thin veneers?
