Proximal Contact Areas
Page 29 of your text book
Class Exercise
21
Proximal Contact Areas
Where mesial and distal (proximal) surfaces of adjacent teeth touch one another
Labial View
Buccal View
Class Exercise
22
Anterior teeth near the incisal third of the teeth
Posterior teeth near the middle third of the teeth
Labial View
Buccal View
Proximal Contact Areas
Class Exercise
23
Incisal View Anterior teeth centre of lingual and labial (middle third)
Occlusal View Posterior teeth slightly buccal to the centre of the tooth

Embrasures
Page 30 of your text book
Class Exercise
25
Embrasures
Spaces between the teeth that diverge, buccally, labially or lingually and occlusal/incisal to the contact areas
Labial View Buccal View
Class Exercise
26
Embrasures
Allow for the passage of food around the teeth so it is not forced in to the contact areas
Dissipate and reduce the forces of occlusal trauma
Self-cleaning, because of the rounded smooth surfaces

Interproximal Space
Proximal surfaces of the teeth form the sides of the triangle
Alveolar bone the base
Contact areas the apex
Class Exercise

Interproximal Space
Usually filled with gingival tissue, this helps prevent food collecting
