10/3 - Integrity Direct Provisional, Splint Design Flashcards
do you place vaseline on plastic tooth before placing integrity?
yes - but the provisional shouldn’t stick onto the plastic tooth w/ or w/o vaseline
what to do in 0-5 seconds of integrity provisional
material dispersed into prelimenary impression
what is done from 5-45 s of integrity provisional
material insert into mouth
what is done after is 2-3 minutes of intergrity provisional
remove from mouth
what is done after 6 minutes of integrity provisional
remove oxygen inhibited layer and begin to trim with rotary instrument
what is done after 7 minutes of integrity provisional
complete contours and polish
indications for using integrity provisional
direct fabrication of terporary provisionals, veneers, inlays, onlays, crowns and bridges used in INDIRECT procedures
are integrity provisionals indicated for FDP
no
what is an occlusal splint
- overlay of occlusal surface(max/mand)
- printed or PMMA (jet acrylic)
why/when do we use an occlusal splint
- protect teeth
- symptom management (provide comfort/relief)
- diagnostic evaluation
- co-discovery
what is the clinical component in splint design
clinical examination/patient interview
what is the diagnostic/occlusal analysis component of splint design
evaluation of casts/mountings
what clinical findings are done in the study of splint design case
- comprehensive exam
- occlusal analysis
- skeletal classification
- functional scheme
- restorative history
- patient interview
what is the basic principle of occlusion
broad stable posterior support and effective anterior guidance
what curve is this
spee
what curve is this
wilson
when observing the mandibular cast, you should be able to predict what?
what the maxillary cast would look like
what does the vertical component of articulator determine
thickness of splint
what to do when determining vertical component
- open vertical dimension by setting pin so that it creates an environment for thinnest splint (>2mm)
- default to 3-4 mm thickness
- look at both sides of arch
what should the vertical component/thickness of splint be
3-4 mm
what does the horizontal component determine for splint design
amount of necessary guidance (group or canine)
what to do when determining horizontal component
- provide appropriate amountof posterior disculsion
- manipulated by the wings of mechanical guide table
the STEEPER the guidance, the ___ posterior disclusion
quicker
the SHALLOWER the guidance, the ___ the posterior disclusion
more gradual
how many mm clearance at the canines
2 mm
the [small, large] knob sets the pitch, the [small, large] knob will lock the wing once in the desired position
large (bottom) knob; small knob
do you want posterior interferences
no
splint design is sent to what printer
Asiga printer
Asiga machine prints a ___ using a file that was generated at the design step
resin splint
how long does it take to cure the splint
an hour
