what are the pre-cementation checks for crowns
is restoration what we asked for
rocking, contact points, marginal integrity, aesthetics
check adjacent teeth contacts to make sure undamaged
occlusal interference on excursions
natural teeth are still contacting
check occlusion
crown thickness
patient happy with appearance
384
what are the post-cementation checks for a crown
excess cement removed
no space around margins
interproximal contact point exists and is clear
occlusion checked with articulating paper
restoration cleansable
confirm patient happy with aesthetics and feel
385
what are the headings on a treatment plan
immediate
initial
re-evaluation
re-constructive
maintenance
386
how do you check if there is going to be occlusal interference with a crown before you put it in the patients mouth and what do you do if there is interference
drop incisal pin onto table and calculate difference
- if do-able to trim without making it too thin then do this chairside
- if not doable them send back to lab
387
what are the crown prep principles
taper of 6 degrees
retentive grooves/slots
bevel functional cusps

388
how do you avoid issues with crown thickness interfering with the occlusion
measure temp crown thickness before cementing
use sectioned putty index when prepping
