All or nothing
Function
the case of dynamic grinding in – in
contrast to static grinding in – the gui-
de surfaces can be very finely prepared
from the palatal (Fig. 17 to 20).

where there is penetration and “grinds” in this high
spot

prepared without a virtual articulator

the guide surfaces in function without high spots in protru-
sion or laterotrusion
