1

what are the uses of partial dentures?

- appearance: fill in gaps from missing teeth
- speech: better articulation of words
- mastication: more efficient chewing
- prevent attrition
- prevent unwanted tooth movement: drifting, tilting, overeruption
- prevent tongue spread
- helps with maxillofacial defects: congenital/acquired (obturators)

describe the kennedy class 3 saddle

single bounded saddle that does not cross the midline

9

describe the kennedy class 4 saddle

single bounded saddle that crosses the midline (anterior teeth)

10

what if there is more than one edentulous saddle present?

modifications are used to refine the basic classification

11

how is the main classification defined?

the most posterior saddle is used, second saddle is the modification
