Exactly.
I learned not to drink the koolaide long ago.
Remember Artglass?
Mark Jackson said he ate somewhere around 10k remakes.
After that, he became a BIG proponent of FDA and good manufacturing processes.
Otherwise, no legal recourse.
So yeah, show me the beef. I don't deny these are gorgeous.
I want to hear evidence of all these claims about flexure, bone loss, etc.
I want to hear about the potential for delamination of all those flexing layers of disparate materials.
I been asking for a couple of years now, and so far it's bubkis.
agreed...I'd love to see real research...3 years ago we were told all the same stories about peek, and now we hear about solubility issues and breakdown of the material intraorally.
Historically we tend to bet very badly on the new materials being "what they are sold as". The result is the 'house' wins in our little gambling adventures, but we, and the patients, suffer.
inceram, spinell and various alumina and silica variants, renaissance crowns, artglass, belleglass, sculpture, targis, emax 2, lava ultimate, all the hybrid nano ceramics, all the polymers (except for this one...maybe) and so many more that I have erased from the memory banks except to be very wary.
the other side of the column for the same time period - leucite reinforced, lithium disilicate, zirconia and.....well that's about all I can think of
irrespective of all that, how much do you charge for one of these? Without knowing specifics of the manufacturing process it looks like about 2 grand of crown and bridge on top of a thousand dollar substrate and a five hundred bucks of parts? So $4000? or perhaps a better question is are you charging more or less than an all on 4 type solution? And can it be coded as a permanent restoration with a polymer substrate or does that limit it to a 'temporary' prosthesis?
