Thanks for writing and for the kind words! Here are some attempts at answering your questions:
1) It is very helpful to include that information; however, if you parallel the incisal edges of your preps to the interpupillary line, that is our default way of mounting the cast. That being said, it is much easier for us to do that if a Kois Dento-Facial Analyzer, or even a stick bite, is included.
2) The one I like best is the SeeMORE retractor from Discus Dental. There are rumors that they may stop selling that product, so I am looking into having it made here at the lab because we have an injection-molding machine on the premises.
3) The contact/seating issue is the worst thing about no-prep veneers. Sometimes I have the lab make a little finger of ceramic on the incisal edge of the veneer to prevent overseating, but then you have to grind that all away after bonding it into place. Really, it all comes down to “feel” and some educated guesswork. I hate procedures like that, but I haven’t found a better way yet.
4) You never have to ask for shade-adjustable ceramic anymore because it is now the material we use on all these types of cases, except for the ones where we are trying to block out a darker shade of tooth — something lower in value than an A3. In those cases, we either need to opaque the inside of the veneers or have the doctor prep the tooth so we can make the veneer a little thicker.
Since that video was produced, however, I now do nearly all my veneers in IPS e.max® (Ivoclar Vivadent; Amherst, N.Y.). Because it is three times stronger than IPS Empress® (Ivoclar Vivadent), I have yet to experience any of the incisal chipping or breakage that I did over the years with IPS Empress. In fact, IPS Empress is dying a slow death in our laboratory, while the number of IPS e.max veneers we do continues to grow. I foresee a time in the not-too-distant future when all veneers will be IPS e.max because of its optimum esthetics and strength.
Hope that helps!
