anatomical and clinical crown
What is the periodontium?
The oral hard and soft tissue that supports the teeth
When looking into a healthy oral cavity when will most likely see
The clinical crown
The term that describes a space continuous with an inter-proximal space, produced
curvature's of teeth in contact in the same arch, that provides a channel or a passage
through which food escapes from the occlusal surfaces of the teeth during mastication
Embrasures
Which embrasure is located below the contact area
Gingival
When posterior teeth are viewed from the occlusal, The proximal contacts are usually
located
more buccal in a buccal to lingual direction
When anterior teeth are viewed from the incisal , the contact area is located
more center in a buccal to lingual direction
