Intended Use

Renamel® NANO™ +plus is designed for, - Class I-V dental restorations - Direct veneering of anterior teeth - Splinting - Repair of composite or ceramic restorations

Device Story

Renamel Nano +plus is a light-cure composite resin used by dental professionals for restorative procedures. The material consists of multifunctional acrylic monomers and silicaceous fillers. It is supplied in preloaded syringes or unit dose compules. The clinician extrudes the material into the prepared cavity or onto the tooth surface and cures it using an LED or Halogen light (400-500 nm). The device mimics natural tooth appearance, providing esthetic qualities for anterior veneers and structural support for splinting or repairs. By restoring tooth structure and function, it benefits patients requiring dental rehabilitation.

Clinical Evidence

Bench testing only. Performance data compared against ISO 4049:2009 standards, including depth of cure, flexural strength, water sorption, solubility, radiopacity, compressive strength, and modulus of elasticity. Biocompatibility evaluated per ISO 10993-xx.

Technological Characteristics

Light-cure nano-hybrid composite resin; multifunctional acrylic monomers and silicaceous fillers. Dimensions/form factor: preloaded syringe or unit dose compules. Curing: LED/Halogen (400-500 nm). Standards: ISO 4049:2009 (Type 1, Class 2, Group 1).

Indications for Use

Indicated for patients requiring Class I-V dental restorations, direct veneering of anterior teeth, splinting, or repair of composite/ceramic restorations.

Regulatory Classification

Identification

Table 5.1: Comparison of Renamel® NANO™ +plus / Renamel® NANO™ (K070583)

# Substantial equivalent in Safety and efficacy (Biocompatibility)

The data analyzed from the toxicological evaluation of the new added components, and the results of the biocompatibility tests (10993-xx) substantiate that the Renamel® NANO™ +plus is safe and effective as the predicate Renamel® NANO™ (K070583).

# Results/summary of the Substantial Equivalence

The subject device Renamel® NANO™ +plus has been compared with its predicate Renamel® NANO™ with regard to indication (intended use), performance data and chemical composition. In order to obtain better handling properties (stiffness and sculptability), the composition of the device has been modified. None of the new ingredients in the subject device poses any new concerns of safety and effectiveness, and comparison shows, that Renamel®NANO™+plus is substantially equivalent to the predicate Renamel®NANO™ (K070583).
