Stae is a fluoride releasing single component dentin / enamel total - etch adhesive system, designed for direct bonding. Stae completely and homogeneously infiltrates the hybrid layer to ensure superior bonding to the tooth.
Acrylic monomer Acetone Fluoride Stabilizer
I) All direct restorative composites
II) Compomers III) Composite / Ceramic+ / Metal+ / Porcelain+ repairs. + Bonding surface requires pre-treatment with a silane primer.
I) Not to be used in combination with chemically-cured composite resin
II) Do not use for pulp capping
III) Any persons having known resin allergies should refrain from using Stae
IV) Not to be used in combination with eugenol materials or hemostatics containing ferric compounds
V) Not to be used in combination with desensitising agents.
One bottle system
Stae combines both primer and adhesive in one bottle to simplify the technique and decrease patient chair time.
Fluoride’s cariostatic effect enhances remineralization and inhibits enamel demineralization. In an aqueous environment, the fl uoride ions in Stae diffuse from the resin into the surrounding tooth. This ionic movement is caused by oral fl uid passing in and out of the resin and tooth, acting as a carrier for the fl uoride ions.
Non Bis-phenol A
Stae avoids the Bis-phenol A hormonal imbalance controversy, as it does not contain the related BisGMA resin.
Bonds to moist and dry tooth surfaces
Stae’s carrier solvent is a mixture of acetone and water. The acetone carries Stae deep into the demineralized dentin and the water re-moistens any dry dentin.
High bond strength
Stae’s complete hybridization of the resin into the demineralized dentin results in high bond strength.
1. Clean and isolate tooth. Rubber dam is the preferred mode of isolation
2. Prepare a conservative cavity, employing standard techniques
3. Use a calcium hydroxide liner and appropriate glass ionomer cement liner to protect deep cavity preparations in close proximity to the pulp
4. Thoroughly dry the bonding surfaces of the tooth with dry, oil-free air
5. Etch with Super Etch 37% phosphoric acid (SDI Limited) for at least 20 seconds.
NOTE: Enamel subjected to fluoridation should be etched for 90 to 120 seconds.
IMPORTANT: If using an etch syringe, ensure that the dispensing tip hub is firmly attached to the syringe by twisting the hub securely onto the syringe. On first usage or after prolonged storage, extrude a small amount onto a mixing pad for familiarity with the etchant’s viscosity and rate of extrusion. 6. Wash thoroughly with water.
7. Remove excess water. Keep moist. Avoid contamination e.g. saliva.
8. Apply Stae to saturate all internal surfaces
9. Blow gently with dry, oil-free air to evaporate solvent. Leave surface glossy
10. Light cure for 10 seconds.
NOTE: do not polymerize Stae by itself in a mixing well; it will be a non – polymerized looking material. Stae contains a unique hydrophobic and hydrophilic monomer that does not cure when exposed to oxygen. The product will polymerize once covered by any lightcure composite restorative material
11. Place composite in increments of 2mm or less.
