STEP-1

Cavity Preparation
It requires minimum cavity preparation. Preparation of cavity design for mechanical retention is not needed except when restoration is liable to be subjected to high displacement forces.

STEP-2

Cleaning
Surface cleanliness is paramount for the development of adhesion. Clean freshly cut enamel and dentine with water spray and air-dry. Where no cavity preparation is necessary, clean the tooth surface with a rubber cup and pumice or a prophy paste (Zircate® or Nupro®). Wash thoroughly with water spray and air-dry.

STEP-3

Pulp Protection
In deep cavities cover the dentine closest to the pulp with a calcium hydroxide liner (Dycal®) leaving the rest of the cavity floor and walls free for chemical bonding with ChemFil Super.

STEP-4

Surface Conditioning
For surface conditioning, ChemFil Tooth Cleanser or ChemFlex™ Liquid may be used. Apply ChemFil Tooth Cleanser or ChemFlex Liquid to the cavity surface and allow it to remain for 15 seconds. Wash off and remove rinsing water, leaving a moist surface.

STEP-5

Shade Selection
ChemFil Superior is available in 7 shades. Shade selection is made with the shade guide supplied. As the translucency and color of glass-ionomer cements change during the first hours after placement, the shade guide represents the final shade of the restoration.

DOSAGE AND MIXING

Mix ratio

2 scoops powder: 2 drops liquid:
Fill the water dispenser with distilled or deionized water and place the plastic insert into the neck. To dispense water, hold the bottle vertically above the pad and squeeze gently. Always invert the powder bottle before use to fluff the powder. Overfill the powder scoop and strike off the excess with the bottle insert leaving a flat surface level with the edge of the scoop. Take care not to press the powder into a scoop, as this can give too thick a mixture

Mixing
Mix the product using a stainless steel or agate spatula on the mixing pad provided or a glass slab2. Divide the powder into two equal parts. Mix the first part with the water in five seconds or less, then add the second part and mix for about ten seconds – maximum mixing time 20 seconds. The consistency of the mixed material should resemble that of a composite resin
