2Glass Ionomer Cements Terminology
What is a Glass Ionomer? Glass Ionomer
Technically glass ionomer is a classification
and glass ionomer cement is a glass ionomer
used for cementing applications. glass refers
to the glassy ceramic particles and the glassy
matrix (non-crystalline) of the set material,
while ionomer refers to ion-crosslinked
polymer. Glass ionomers contain and release
fluoride, which is important to preventing
carious lesions. General Applications Type I
Luting crowns, bridges and orthodontic brackets
Type II a Aesthetic restorative
cements Type II b Reinforced restorative
cements
Type III Lining cements, Base. The chemistry
is essentially the same for all three categories,
but there are variations in powder / liquid ratio
and powder particle size to accommodate the
desired function. Features Bond adhesively
to enamel dentin Release fluoride ions
over a prolonged period of time Biocompatible
have approximately same coefficient of thermal
expansion as that of tooth structure. Polyalkeno
ic or Polyalkenoate refers to polymer chain
which incorporates alkenoic monomers such as
acrylic acid, tartaric acid, maleic acid,
etc. F-Release refers to release of fluoride
ions. Multiple-Cure refers to multiple curing
mechanisms possible with resin-modified systems.

particles at different rates.

5GI Comparison
- Glass-Ionomer terminology has become quite
complicated and with so many products in the
market it is hard to know what to choose. The
products available have different enhancements to
make them more suitable for specific indications. - In general there are three classifications of GIs
- a) Glass Ionomer Cements or traditional glass
ionomer restorative products. - Consist of an acid-decomposable glass and an
acidic polymer that undergo an acid/base reaction
when mixed. The reaction does not require light
to occur - the mixed material sets in the dark. - Examples of these products are Ketac-Fil (ESPE)
and Fuji II (GC America). - b) Resin-Modified Glass-Ionomer Cements
- This group can be divided into 2 subgroups
Light Cured Resin Modified Glass Ionomer
Base/Liners Light Cured Resin Modified Glass
Ionomer Restoratives. - Resin has been added in one form or another. In
addition to the GI acid/base reaction, they also
undergo a resin polymerization reaction that is
usually initiated by light exposure (these
products require light exposure to harden.)
Examples are Fuji II LC (GC America), Vitremer
(3M), and Photac-Fil (ESPE). - c) Polyacid Modified Composite Resins
- These are more resin than glass ionomer. They
contain one or both of the basic glass-ionomer
components but the components are in such small
quantities that they either do not cause an
acid/base glass-ionomer setting reaction or
contribute little to the overall setting reaction
of the material. These products usually do not
set without light exposure or set very slowly. - Examples are VariGlass VLC (Caulk), Dyract
(Caulk), and Geristore (Den-Mat).
