In a non-working movement, which structure of the maxillary 1st molar moves through the distobuccal groove of a mandibular 1st molar in a class I ideal occlusion?
My answer was Distolingual cusp, however DBM's answer was distobuccal cusp.
I keep thinking its distolingual though so maybe my thought process is wrong. Can someone chime in?
