This submission covers four light-curing, radiopaque, polymer-based dental composite resins (Venus Diamond, Venus Diamond Flow, Venus Pearl, and Venus Bulk Flow One) supplied in syringes and prefilled units for professional dental use. They are indicated for direct restorations, cavity linings, repairs, splinting, fissure sealing, and new uses including composite attachments for clear aligner therapy and retainer fixation.
All four devices are nano/nanohybrid composites containing inorganic fillers (barium alumino-borosilicate glass, silica, ytterbium fluoride), dimethacrylate resins (UDMA, TEGDMA, TCD-urethaneacrylate), initiators, stabilizers, and pigments. They are polymerized with dental curing lights at 450–480 nm wavelength and 600–1550 mW/cm². Each device has identical composition to its respective predicate with no formulation changes.
ISO 4049 (polymer-based restorative materials) for flexural strength, radiopacity, and depth of cure; ISO 10993-5, -10, and -11 for biocompatibility; and internal validated methods for wear resistance, bond strength, thermal cycling, shrinkage, and surface polishability.
The applicant devices are substantially equivalent to their respective predicates because they have identical compositions, meet or exceed all performance testing requirements (flexural strength ≥100 MPa, radiopacity 2.0–3.5 mm Al, appropriate depth of cure), and demonstrate biocompatibility. The addition of aligner-related indications (composite attachments, retainer fixation) does not alter the general intended use or mechanism of action and is supported by bench testing and reference device experience without raising new safety or effectiveness questions.
