I have used them on my patients, smaller foot print and I think, easier for those who cannot
handle the precision since walls are not parallel.
Also, can get taller abutments (like 6 or 7mm) when the pt not willing to remove excess soft tissues
after the fact. I like working with Joe at Rhein 83 also.
Their catalog fairly extensive, and they have to use specific drivers but you can get a latch
for a Nobel manual wrench holder.
Let me know if you need more info, and good to hear from you, Darwin.
