Ceramic 2 Flashcards
▸Temporary cement
▸Soothes pulp
▸Eugenol inhibits polymerization of resin
▸Ex: Temp Bond
Zinc oxide eugenol
▸Temporary cement
▸Chelation to calcium
▸Minimal pulpal irritation
▸Ex: Durelon
Zinc polycarboxylate
▸Phosphoric acid irritates the pulp
▸Mix on a chilled glass slab due to
exothermic reaction
Zinc phosphate
▸Adheres to enamel and dentin
▸Releases fluoride
▸Less post operative sensitivity.
▸Ex. Fuji
Glass ionomer
▸Higher strength and lower solubility than GI
▸Contraindicated with low strength ceramics due to expansion from water
absorption and possible fracture of ceramic at thin margin area.
▸Can be used with zirconia.
▸Less post operative sensitivity.
▸Ex: Rely-X Luting
RMGI
▸Most compressive strength
▸Bonds to dentin
▸Light cure, Chemical cure, or dual cure varieties
▸Light cure cement is more color stable than dual
cure cement*
▸Recommended for low strength ceramics
Resin cements
What type of cure resin (chemical, dual, light cure) cement is the most color stable?
Light cure
How is glass ceramics internal surface preppared for cementation?
Hydrofluoric acid etch
