Might be more than you want to share, but Im curious how you arrived at that.
No human has ever been recorded to have less than 25°, not even close.
If it misses at 20° it will miss at anything steeper. When I do digital work ups I am not always certain that the restoration will be fixed.
An old mentor of mine did dentures at 25°.
@kcdt Most of my patients are older than Methuselah, they have broken down dentition and some have had broken down. condylar capsules. I've had a lot of success at 20° for an average and I'll stay there until something dictates a change.
Also, if you use anything flatter than what the patient actually has using exo virtual articulator the protrusive and excursive movements in the software are dictated by the position of the teeth.
The process may change since we started using gothic arch tracers on all full arch/mouth restorations regardless if fixed or removable.
@kcdt <--- thanks!
