I understand satire, but I dont understand insinuating someone is a neanderthal on a subject you know little about. The "digital.. 'cuz" argument just doesnt apply to everything. Maybe I missed your point..
I use a panadent setup with a facebow for most all of my FUD/FLD. I think the teeth determine the occlusion in most cases. I use candulor teeth with steep cusp/fossa occlusion so I think a semi adjustable is appropriate when using $100 teeth like that, zero degree teeth I guess are fine on a clacker.
at the end of the day the facebow is one of those sources of error, as is the impression, and bite. they were taken maybe with the most advanced methods by hand, but they are not methods that account for the patient's rest state, nor actual degree of movement.
this is where digital will eventually bring denturism from "flatten all the teeth because we cant have it any other way" to "give me natural anatomy"
because with digital tools will be the ability to scan the TMJ and digitally calculate with precision the full range of movement. scan via CBCT and IOS and merge the data for the best rest position.
then you will have a point from which to start that is orderS of magnitude more precise and advanced than poorly taken impressions with shoddy bites mounted on a glorified door hinge. or any sort of facebow and pinned articulator.
do you understand how "I think the teeth determine the occlusion in most cases" sounds so much like Abe describing the the word Thousand ?
in his book The Hitchikers Guide to the Galaxy there is a quote: We'll be saying a big hello to all intelligent lifeforms everywhere and to everyone else out there, the secret is to bang the rocks together, guys.
it just means theres opportunity for growth and catch up with the more advanced, and it just needs a little coaxing to get off the ground.
