Design Principles of RPDs Flashcards
what are the aspects of denture design?
saddles, support, retention, indirect retention, bracing/reciprocation, connectors, review and simplify
what are saddles
teeth being replaced
what is support
the resistance of the denture to occlusally directed load
what is retention
resistance of the denture to vertical displacement
what are the methods of retention
clasps, soft tissue undercuts, adhesion, friction, path of insertion, precision attachments/implants
what is indirect retention?
resistance to rotational displacement
what is reciprocation
prevents a clasp arm moving the clasped tooth
what does a major connector do?
connects all the components
what does a minor connector do?
connects rests, clasps and bracing arms
what are the different types of upper major connector
bar, horseshoe, plate PMMA/CoCr
what are the different types of bar connector design for an upper denture?
strap, ring
what are the different types of lower connectors?
CoCr bars (lingual sub-lingual, dental), plates (CoCr, PMMA)
