ADEX OSCE, EXAM Questions and answers, rated A+ thickness of minor RPD connectors - -1.5 mm Minimum space between vertical components of RPD - -5 mm Kennedy Class I - -bilateral distal extension Kennedy Class II - -unilateral distal extension Kennedy Class III - -entirely tooth born with teeth anterior and posterior Kennedy Class IV - -edentulous area anterior to remaining teeth Lingual bar distance from gingival margin - -3 mm Lingual bar width (minimum) - -4 mm Maxillary major connectors, how far from gingival margin - -6 mm Max RPD bead line width and depth - -.75-1 mm Anterior-posterior palatal strap, minimum distance between straps and minimum width for each strap - -15 mm between, 6 mm anterior and 8 mm posterior Palatal plate advised when? - -The last abutment on either side is a canine or premolar Main function of indirect retainers - -prevents vertical dislodgement of the distal extension base away from tissues (sticky food) Minimum number of rests for RPD - -3 For a distal extension where is the rest on the most posterior tooth - -mesial rest seat depth - -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 - -guide planes extended occlusal rests used when? - -used when most posterior molar abutment is mesially tipped in class II (mod I) and class III Cingulum rest depths - -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 - -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 - -kennedy classification + 1 (except for class IV) Undercut of 0.01 - -cast clasp Undercut of 0.02 - -wrought wire (0.5 mm and must be at least 8 mm long, 18 gauge) chromium provides what - -corrosion resistance cobalt provides what - -rigidity Nickel provides what - -ductility What muscle dictates the DB of the mand flange of a denture - -masseter What muscle dictates the DL of the mand flange of a denture - -superior constrictor muscle how far to trim back the custom tray from the mucosal reflection - -2 mm occlusion rim heights - -maxillary 22 mm, mandibular 18 mm The inferior surface of the maxillary occlusal rim should be parallel to... - -Camper's Line (Ala-tragus Line) and inter-pupillary line primary and secondary support for mand denture - -primary - buccal shelf, secondary - alveolar ridge Posterior palatal seal - -extends through the hamular notches, 2 mm in front of fovea palatinae, carried 5 mm anterior to the vibrating line if denture falls down when smiling - -buccal notch and buccal flange are excessively thick Golden Proportion Ratio - -1.6:1:0.6 (central:lateral:canine) S sounds like "th" - -either max anteriors are too far palatal or palate is too thick. S sounds bring the max and mand closest together (than other sounds) Occlusal clearance gold - -1.5 mm functional, 1 mm non-functional Occlusal clearance PFM - -1.5-2 mm functional, 1-1.5 non-functional all ceramic clearance - -2 mm
