Bridgework 3 Flashcards
what is holistic treatment planning
looking at the whole mouth not only a specific tooth and plan for the future
what occlusal information must be gathered
initial classification
canine guidance or group function
opposing tooth overerupted
will bridge interfere with occlusion
signs of parafunction present
what must be considered when designing bridges
prep
materials
abutments
cleansability
appearance
what is looked at when evaluating abutments
root configuration
angulation of abutment
perio health
surface area for bonding
pulpal damage risk
quality of endodontics
remaining tooth structure present
core
what is included in bridge design
abutment teeth selected
retainer type selected
pontic and connector
plan occlusion
prescribe material
what is the function of a pontic
restore appearance of missing tooth
stabilise occlusion
improve masticatory function
what must be considered with pontic design
cleansability
appearance
strength
what must the occlusal surface of the pontic be
resemblant to tooth it replaces
narrower to enable cleaning
sufficient occlusal contact
what are the different types of pontic
wash through
dome shaped
modified ridge lap
ridge lap-saddle
what materials are used for bridges
metal
metal ceramic
all ceramic
ceromeric
what is lava 3m espe
3-4 unit fixed bridge milled zirconium oxide frame with feldspathic porcelain overlying
what is parallelism
two or more teeth to be prepared in a manner to provide a common path of insertion for increased retention
how do you check parallelism
direction vision
large mouth mirror
straight probe used like surveyor
what is used to definitively cement metal and metal ceramic bridgework
aquacem
what is used to cement adhesive bridges
panavia
