Spring Reading: CAD/CAM II & Ceramic Materials Flashcards
How do 5y survival rates of metal ceramic, all ceramic leucite or LiDi reinforced glass ceramic, glass infiltrated alumina, and densely sintered alumina and zirconia compare?
all about 95% 5y survival
5y survival rate of these were lower:
feldspathic/ silica based ceramic crowns
How did feldspathic/ silica based ceramic and zirconia crowns compare bw ant and pos regions?
sig lower survival rates in pos
Which were more frequently lost due to veneering ceramic fractures, metal ceramic or densely sintered zirconia?
densely sintered zirconia
Which had significantly more loss of retention, metal ceramic or densely sintered zirconia?
densely sintered zirconia
Which had higher framework fracture, all ceramic or metal ceramic?
all ceramic
How do survival rates, both in ant and pos, compare for all ceramic and metal ceramic?
similar
Feldspathic should only be used here:
anterior region
TF? Zirconia based single crowns should not be considered a primary option due to their high incidence of technical problems.
T
Loss of retention was most freq reported for:
zirconia
Main complication of ACC:
catastrophic framework fracture
Non-catastrophic issue:
chipping of veneering ceramic (both ACC and MCC)
Biological compatibility comparison, ACC vs. MCC:
ACC, abutment tooth fracture and death more common for MCC
Other materials that produced favorable reviews:
reinforced ceramics and oxide ceramics
Despite not a recommendation for use as SC, zirconia showed enhanced:
mechanical stability
