CORRECT | 100% VERFIED | ALREADY GRADED A+
thickness of minor RPD connectors - (answer)1.5 mm
Minimum space between vertical components of RPD - (answer)5 mm
Kennedy Class I - (answer)bilateral distal extension
Kennedy Class II - (answer)unilateral distal extension
Kennedy Class III - (answer)entirely tooth born with teeth anterior and posterior
Kennedy Class IV - (answer)edentulous area anterior to remaining teeth
Lingual bar distance from gingival margin - (answer)3 mm
Lingual bar width (minimum) - (answer)4 mm
,Maxillary major connectors, how far from gingival margin - (answer)6 mm
Max RPD bead line width and depth - (answer).75-1 mm
Anterior-posterior palatal strap, minimum distance between straps and minimum width for each
strap - (answer)15 mm between, 6 mm anterior and 8 mm posterior
Palatal plate advised when? - (answer)The last abutment on either side is a canine or premolar
Main function of indirect retainers - (answer)prevents vertical dislodgement of the distal
extension base away from tissues (sticky food)
Minimum number of rests for RPD - (answer)3
For a distal extension where is the rest on the most posterior tooth - (answer)mesial
rest seat depth - (answer)1.5 mm at marginal ridge and 2 mm in center, at least 2.5 mm wide
, what is prepared first? Guide planes or seats - (answer)guide planes
extended occlusal rests used when? - (answer)used when most posterior molar abutment is
mesially tipped in class II (mod I) and class III
Cingulum rest depths - (answer)2 mm wide (F-L), 2.5-3 mm (M-D), 1.5 mm deep
Guide plane position relative to height of contour for classes of RPD - (answer)Class III and IV
can end above the height of contour because there is no functional movement. Class I and II must
be below the height of contour (to prevent torquing). With I-bars and mesial rests on premolars,
must end exactly at the height of contour.
how to determine number of clasps - (answer)kennedy classification + 1 (except for class IV)
Undercut of 0.01 - (answer)cast clasp
Undercut of 0.02 - (answer)wrought wire (0.5 mm and must be at least 8 mm long, 18 gauge)
chromium provides what - (answer)corrosion resistance
