Framework and Trial Insertion Flashcards
what are the three options for this stage?
framework only, framework with wax record blocks, framework with tooth trial in wax
with the framework only what should you check?
the name of the patient, framework matches design, does it fit the cast, is there damage to the casts, is the articulator pin on the table
how are the frameworks returned?
on the articulated master cast
how do you try in the framework?
carefully remove from the cast, disinfect, try in the mouth and assess is seats correctly, check clasp adaption and undercut engagement, use articulating paper to identify minor occlusal errors
what would the error be if the framework fits the cast and is undamaged but not the patient?
impression error
what would the problem be if the framework fits the cast but not the patient and the cast is damaged?
incorrect blocking out, inappropriate design, clasps too thick with insufficient flex
when do you use occlusal rims?
added to framework to record the jaw relationship again if this is found to be in error, complex cases when upper anterior teeth are missing
what do you check with framework with wax record blocks
name of patient, framework matches design, does it fit the cast, is there damage to the cast
how do you try in framework with wax record block?
carefully remove from the cast, disinfect, try in the mouth and assess fit, check clasp adaption and undercut engagement, adjust wax record blocks
what do you check with framework with tooth trial?
name of patient, framework matches design, does it fit the cast, is there damage to the casts, does the tooth position and shade look correct, is the articulator pin on the table
how do you try in the framework with tooth trial?
remove carefully from the cast and disinfect, carefully try in the mouth, framework fit has already been verified but check again, addition of wax in the saddle areas may now have improved the fit
what do you check with framework with tooth trial?
aesthetics, occlusion, speech
how do you check aesthetics
shade and mould of teeth, extension of anterior denture flanges
how do you check occlusion
articulating paper, no framework interference, even occlusal contacts on denture teeth
how do you check speech
relaxed conversation with denture in reveals most problems
