GLASS IONOMER

TYPE 1

•It was designed and developed in the

early 70's from older materials.

•The glass ionomer is the most current

and by far the most use and interest.

•Name comes from its composition:

Glass particles produce ions in acid

medium.

• Set structures made out of the mouth to natural tissues of the

tooth.

• As a hard core liner or any dental process.

• As a restorative material into cavities of the necks of teeth and not

receiving zone where occlusion force.

• As Pits sealant in posterior teeth in children

• Are presented as a powder and liquid mixture which,

according to manufacturer's instructions, harden.

•The powder is made of silica, aluminum, calcium and

fluoride.

•The liquid is poly acrylic acid, water and small amounts

of tartaric acid.

It is an acid base reaction cement poly electrolyte. Calcium

and aluminum electrolyte containing the powder form mixed

with the carboxylic poly acid in water.

•Cementitious material.

•Liner or base.

•Restorative material

ADVANTAGES AND DISADVANTAGES

ADVANTAGES DISVANTAGES

Its physical properties are

good, but before masticatio

n loads.

They are more expensive

than the other groups.

It specifies or

chemical adhesion to tooth

and dental alloys.

Not chemically bond to

porcelain and gold alloys.

Shows dimensional

stability.

Are very soluble in the

first 24 hours.

Fluoride release are

more aesthetic than the

other groups of cements.

It does not

allow variables in handling.

• Powder and liquid for manual mixing:

Usually in a bottle with the liquid and in a

boat with the powder.

In capsule to mechanical vibration: the powder

and liquid are inside a capsule, separated

by a membrane which breaks under pressure,

placing the two components in contact. The mixture is

made using a vibrator.
