Intended Use

TrusFIL-Flow Flowable Composite Restorative is a visible light curing dental restorative material indicated for: - Class III and V restorations - Restoration of minimally invasive cavity preparations (including small, non stress-bearing occlusal restorations) - Base/liner under direct restorations - Repair of small defects in indirect restorations - Pit and fissure sealant - Undercut blockout - Repair of resin and acrylic temporary materials

Device Story

TrusFIL-Flow is a visible light-curing dental restorative material; composed of methacrylate-based resins (Bis-GMA, TEGDMA, EBPADMA) and inorganic fillers (approx. 46% volume, 0.01-3 microns). Supplied in syringes or single-dose capsules for single-patient use. Used by dentists in clinical settings to restore carious lesions or structural tooth defects. Applied in combination with bonding agents, luting, or etching agents. Hardened via light curing. Radiopaque for radiographic visibility. Benefits include restoration of tooth structure and aesthetics; provides a flowable consistency for precise placement in cavity preparations.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by in-vitro bench testing, including ISO 4049:2019 standards (sensitivity to ambient light, depth of cure, flexural strength, water sorption/solubility, shade, color stability, radio-opacity) and internal standards (elastic modulus, surface hardness, compressive strength). Biocompatibility testing performed per ISO 10993.

Technological Characteristics

Methacrylate-based resin composite (Bis-GMA, TEGDMA, EBPADMA) with inorganic fillers. Flowable paste form. Light-cured. Radiopaque. Packaged in syringes or single-dose capsules. Complies with ISO 4049:2019, ISO 7405, and ISO 10993-1. No software or electronic components.

Indications for Use

Indicated for dental patients requiring Class III and V restorations, minimally invasive cavity preparations, base/liner placement, repair of indirect restoration defects, pit and fissure sealing, undercut blockout, and repair of resin/acrylic temporary materials.

Regulatory Classification

Identification

Tooth shade resin material is a device composed of materials such as bisphenol-A glycidyl methacrylate (Bis-GMA) intended to restore carious lesions or structural defects in teeth.
