*Golden- NBDE II- dentures/ RPD/ fixed prosth UPDATED
ACTUAL Questions and CORRECT Answers
Retentive Clasp engages undercut below height of contour
(gingival 1/3 of crown within the undercut- SUPRAbuldge)
*NOT a base metal alloy
Reciprocal Clasp passively touch above height of contour
(middle 1/3 of crown)
Requirement of major connector Rigidity (support)
2 main purposes of MAJOR connector Rigidity (support), stability
what does reciprocating arm of clasp do? 1. counteracts retentive clasp
2. stabilization
3. indirect retainer
function of a rest prevent displacement (resist vertical tissue force) / support
purpose of indirect retainer - prevents displacement of denture base
- on oposite side of fulcrum
most important in denture retention peripheral seal
primary retention for max denture residual RIDGES / palate
(main stress bearing areas) secondary- rugae
primary retention for mand denture buccal shelf
(main stress bearing areas) secondary- anterior lingual border
, best indicator for success of a denture ridge
extends 1-2mm beyond vibrating line max denture
covers 2/3 retromolar pad mand denture
DB flange is determined by... Masseter
most important in denture retention peripheral seal
combination clasp wrout wire (retentive) and cast wire (reciprocal) clasps
what connects the major connector w/ the minnor connector
rest seats
Class I and II - indirect retention? yes
Class III and IV- indirect retention? no
for bilateral distal extension use.. indirect retention (bc it is TISSUE supported)
post extension of PPS is... 2mm beyond vibrating line (fovea palatini)
3 things to determine PPS 1. throat form
2. tissue type
3. fovea location
PPS in max denture will compensate for polymerization and cooling shrinkage
why place PPS? compensates for shrinkage
excessive depth of PPS results in... unseating of denture
if the palatal vault is too deep, what the vibrating line is more pronounced and forward (anterior)
happens to vibrating line?
the higher the palatal vault = the more abrupt and forward the vibrating line
(gives a NARROWER PPS area)
when do you remove palatal tori? when it prevents seating of the denture and formation of the
posterior seal
removing palatal tori will do what for the increase seal
future of the PPS?
palatal tori should be removed when... if posterior to vibrating line- interfere w/ PPS
