Intended Use

NextDent™ Denture / E-Denture is a light-cured resin indicated for the fabrication of denture bases fabricated in dental laboratories, including full and partial removable dentures. The material is an alternative to traditional heat cured and auto polymerization resins. NextDent ™ Denture is intended exclusively for professional dental work. Fabrication of denture bases with NextDent ™ Denture / E-Denture requires a computer-aided and manufacturing (CAD/CAM) system that includes the following: scanner, design software, additive printer and post-cure unit.

Device Story

NextDent™ Denture/E-Denture is a light-cured dimethacrylate-based resin used for 3D printing denture bases. The device is used in dental laboratories by technicians. The workflow requires a CAD/CAM system: a 3D scanner captures dental anatomy; design software creates a digital denture base file; an additive (stereolithographic) printer fabricates the physical base; and a UV-light curing box performs final polymerization. The output is a custom-fit denture base. The device benefits patients by providing an alternative to traditional heat-cured or auto-polymerizing resins for removable prosthetics.

Clinical Evidence

Bench testing only. Performance evaluated against ISO 20795-1 (Denture base polymers). Tested for flexural strength, flexural modulus, water sorption, water solubility, and residual monomer. Biocompatibility testing conducted per ISO 10993-1, including cytotoxicity (ISO 10993-5), sensitization/irritation (ISO 10993-10), and genotoxicity/systemic toxicity (ISO 10993-3).

Technological Characteristics

Dimethacrylate-based resin with photo-initiators and pigments. Non-sterile. Shelf life: 2 years. Compliant with ISO 20795-1 (Type 4 material, meets Type 2 water solubility requirements). Requires external CAD/CAM ecosystem (scanner, design software, additive printer, UV post-cure unit).

Indications for Use

Indicated for fabrication of full and partial removable denture bases in dental laboratories. Intended for professional dental use only.

Regulatory Classification

| VI. COMPARISON OF<br>TECHNOLOGICAL<br>CHARACTERISTICS WITH<br>THE PREDICATE DEVICE | The Indications for Use statement of the predicated device Dentca Denture Base (K143033) is the following: | | | | | | | | | | | | | | | | | | | | | | | | |
| | "Dentca Denture Base is a light-cured resin indicated for fabrication and repair of full and partial removable dentures and baseplates. The material is an alternative to traditional heat cured and auto polymerizing resins. | | | | | | | | | | | | | | | | | | | | | | | | |
| | Fabrication of dental prosthetics with Dentca Denture Base requires a computer-aided design and manufacturing (CAD/CAM) system that includes the following components not part of the device: oral casting impression, digital denture base file created in an optical impression system, stereolithographic additive printer, and curing light equipment." | | | | | | | | | | | | | | | | | | | | | | | | |

{5}------------------------------------------------

| | Both NextDent™ Denture / E-Denture and the<br>predicate device have the following similar<br>characteristics: |
|--------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| | - Both devices are light-cure resins indicated for<br>fabrication of removable full and partial denture<br>bases. |
| | - Both devices require a CAD/CAM system<br>consisting of a scanner, design software,<br>additive printer and post-cure unit. |
| | NextDent™ Denture / E-Denture is not indicated for<br>repair of dentures because in our opinion the<br>stereolithographic technique is not indicated for repair<br>of denture bases. |
| | The difference is in the chemical composition of the<br>specific resin. |
| | NextDent™ Denture / E-Denture is similar to the<br>predicate device in the method of processing. The<br>main difference is the chemical composition of the<br>resin. The chemical composition might influence the<br>biocompatibility of NextDent™ Denture's / E-Denture's<br>denture base, as well as its performance (mechanical<br>properties). Thus, both biocompatibility and<br>performance has been demonstrated for NextDent™<br>Denture / E-Denture. The same tests according to the<br>same standards were used to show biocompatibility<br>and performance of the predicate. |
| | It was concluded, therefore, that the technological<br>differences do not raise different questions of safety<br>and effectiveness. |
| | Based on the Device Comparison Table (section 12.2)<br>and Comparison Demonstration Substantial<br>Equivalence (section 12.3) it was concluded (section<br>12.4) that NextDent™ Denture / E-Denture,<br>manufactured by Vertex-Dental, is substantially<br>equivalent to the predicate device. |
| VII. SUMMARY OF<br>TESTING [PERFORMANCE<br>DATA] | NextDent™ Denture / E-Denture has been tested for<br>mechanical properties as part of the product<br>specification. The most applicable standard for<br>mechanical characteristics determination of denture<br>base polymers and copolymers is the ISO 20975-1<br>Dentistry - Base polymers - Part 1: Denture base<br>polymers. |
| Biocompatibility Testing: | NextDent™ Denture / E-Denture is considered a<br>surface device, in contact with the mucosal<br>membrane, for > 30 days. |
