Aster Flow+ by Kiyomi Dental: light-cured flowable composite for dental restorations.

Aster Flow+ by Kiyomi Dental is a microhybrid flowable restorative composite indicated for the treatment of carious lesions and defects in tooth structure. This light-cured composite resin combines a balanced medium viscosity with self-levelling technology, facilitating precise application and adaptation to tooth surfaces and cavity walls.

Developed for professionals in restorative and aesthetic dentistry, Aster Flow+ offers controlled flow, easy handling and mechanical properties suited to its indications. Its polishability and lasting gloss enable restorations with an aesthetic finish, while its high radiopacity facilitates radiographic identification.

Applications of Aster Flow+ composite in dental practice

The versatility of this flowable dental composite allows it to be used in a range of restorative procedures:

• Class III and V restorations.
• Restoration of minimally invasive cavity preparations, including small occlusal restorations in areas not subject to high loads.
• Use as a base or liner beneath direct restorations.
• Repair of minor defects in indirect restorations.
• Pit and fissure sealing.
• Blocking out undercuts.
• Repair of provisional resin and acrylic restorations.
• Fabrication of orthodontic attachments.
• Creation of mock-ups.

Controlled flow for precise placement

The medium viscosity of Aster Flow+ allows precise handling during dispensing and placement. Its self-levelling behaviour promotes composite distribution and adaptation to irregularities in the preparation. These characteristics are particularly useful in minimally invasive restorations, cavity bases, liners and minor repairs, where application control and surface adaptation are relevant to the procedure.

Composite resin composition and properties

The organic matrix of Aster Flow+ contains Bis-GMA, TEGDMA and EBPADMA. Its formulation incorporates an inorganic filler content of approximately 60–65% by weight and 46% by volume, consisting of silane-treated barium glass and Ca-Zr-silicate. Particle sizes range from approximately 0.01 to 3 µm, equivalent to 10–3,000 nm. This combination of components contributes to the composite’s strength, radiopacity and physical and mechanical properties.

Benefits for restorative dentistry professionals

• Cavity adaptation and material control: Its flowable rheology and self-levelling properties facilitate composite placement and adaptation to tooth surfaces, including small, conservative preparations.
• Mechanical strength for the indicated applications: Aster Flow+ has a flexural strength of 130 MPa. This value, together with its inorganic barium glass and Ca-Zr-silicate filler, contributes to the material’s mechanical performance in the recommended indications.
• Low shrinkage during light curing: Its polymerisation shrinkage of 1.35% supports the composite’s dimensional stability during curing.
• Properties relevant to exposure to the oral environment: The resin has a water sorption of 19 µg/mm³ and a water solubility of 0.48 µg/mm³, parameters that describe its behaviour in contact with water.
• Visibility during radiographic monitoring: With a radiopacity greater than 300%, Aster Flow+ facilitates material identification and radiographic monitoring of restorations.
• Easy polishing and an aesthetic finish: Its polishability allows a surface with lasting gloss to be achieved. The A1, A2, A3 and B1 shades provide different options for aesthetic restorative procedures.
