A

parallel to but slightly LINGUAL

26
Q

What has more distinct MF and DF line angles: Man Lat Incisors OR Max Lat Incisors? POR QUE??

A

NO!

34
Q

A DISTAL tour of the Perm MAND Lat Incisor: Can I see the Mesial Marginal ridge from this view?

A

NO! It is covered by the outline of the Distal Marginal Ridge

35
Q

A DISTAL tour of the Perm MAND Lat Incisor: The cervical line curves less toward the incisal then on the mesial (normal), but MORE IMPORTANTLY: the crest of the curvature is located slightly on the ______ portion of the tooth!

the FL long axis bisector (center of the tooth)

38
Q

A DISTAL tour of the Perm MAND Lat Incisor: The incisal ridge is located slightly toward the ______ surface when compared to the FL long axis bisector (center) that travels through the root apex.

A

Lingual…you have to have them sit BEHIND the maxillary teeth on occlusion!

39
