Occlusion for Partial Dentures - Tutorial 1 Flashcards
what is occlusion
static relationship between the incising or masticating surfaces of the maxillary and mandibular teeth or tooth analogues
what is ICP
complete intercuspation of the opposing teeth independent of the condylar position
what is RCP
guided occlusal relationship occurring at the most retruded position of the condyles in the joint cavities
what are index teeth
contacting facets of teeth in ICP
what do you require for ICP
sufficient index teeth
stable occlusion
what is better - conforming or changing existing occlusion
conforming
what occlusion measurement would you take if you are changing the existing occlusion
RCP
name three ways an interocclusal record can be taken
bite registration paste
wax wafer
modified wax wafer
name the easiest way of solving denture design problems
modify survey lines
what is the purpose of modifying survey lines on a poor denture design
more favourable clasping which improves retention
what are precision attachments
they are like lock and key components that fit into one another and aid retention
name two types of precision attachments
ball and socket
tubelock
what is a two-part denture useful for
when there is gross tissue loss and different paths of insertions
you put the posterior in as normal - anteriorly there will be screws for the second part of the denture to slot into
what is a swinglock denture
useful when no good undercuts on canines
lingual plate and hinge on one side, lock on the other
denture goes in with one lock open - patient closes this
when a patient’s teeth are tilted lingually, and a lingual bar or plate will not fit - what can you use
buccal bar
