Stae

Single component total etch adhesive

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.

One bottle system

Stae combines both primer and adhesive in one bottle to simplify the technique and decrease patient chair time.

Fluoride release

Fluoride's cariostatic effect enhances remineralization and inhibits enamel demineralization. In an aqueous environment, the fluoride ions in Stae diffuse from the resin into the surrounding tooth. This ionic movement is caused by oral fluid passing in and out of the resin and tooth, acting as a carrier for the fluoride ions.

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.

Dental Advisor rating

"Stae is a highly recommended adhesive system designed for composite, compomer, and porcelain bonding. It received an 86% rating."(1)

Complete and consistent hybridization

"SEM observations of the Stae adhesive system revealed hybridization at the dentin-resin interface. The hybrid layer appears well developed with a uniform thickness of around 3 to 4 microns."(2) Stae's well infiltrated hybrid layer, compared to the other brands below, illustrates Stae's complete sealing of the dentinal tubules, minimizing post operative sensitivity. Evident in the photographs is Stae's "intimate adaptation of the interdiffused resin to the remaining sound tooth structure and uniform image density.

There are no gaps or voids visible within the hybrid layer. Such a characterization has previously been associated with adhesive systems with durable clinical success. A similar result was found with 3M Single Bond* adhesive system. With the Optibond Solo* adhesive, a less well defined hybrid layer resulted. Within the layer are areas void of resin interdiffusion. Further, the non-uniform image density suggests a lack of complete hybrid layer development." (3)

Non Bis-phenol A

Stae avoids the Bis-phenol A hormonal imbalance controversy, as it does not contain the related BisGMA resin.

High bond strength

Stae's complete hybridization of the resin into the demineralized dentin results in high bond strength.

No voids

Stae's "hybrid layer is continuous with the residual dentin layer with no evidence of separation or voids."(2)

Complete seal

Stae's "hybrid layer is very uniform with no variation in staining which represents a uniform interdiffusion of adhesive resin into the demineralized layer. The collagen framework appears totally encapsulated with resin."(2)

Intact collagen

"Collagen fibrils within the hybrid layer show evidence of complete banding with no signs of denaturing or loss of structural integrity."(2)

Indications

• All direct restorative composites
• Compomers
• Composite / Ceramic+ / Metal+ / Porcelain+ Repairs

+Bonding surface requires pre-treatment with a silane primer.

Application Instructions

1. Clean and isolate tooth
2. Etch tooth surface with Super Etch 37% phosphoric acid for 20 seconds
3. Wash thoroughly
4. Remove excess water. Keep moist
5. Apply Stae to saturate all internal surfaces
6. Blow gently with dry, oil free air for 2 seconds to evaporate solvent. Leave surface glossy
7. Light cure for 10 seconds
8. Apply composite or compomer, such as Ice, Rok or Wave, according to the manufacturer's instructions
