SDI Stae - 5th Generation Bonding agent

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.

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. 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 hybrid layer 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.”
