Intended Use

SprintRay Denture Base resin is a light-curable polymerizable resin intended to be used for the fabrication and repair, of full and partial removable dentures and baseplates. The material is an alternative to traditional denture base material. Fabrication of dental prosthetics with SprintRay Denture Base resin requires computer-aided design and manufacturing system that includes the following components not part of the device: oral casting impression, digital denture base file created in an optical impression system, 3D printer, and curing light equipment.

Device Story

SprintRay Denture Base is a light-curable acrylate resin for 3D printing dental appliances. Workflow: clinician captures oral impression; creates digital denture base file via optical impression system; prints appliance using 3D printer; cures with UV lamp; trims/cleans in dental office. Used by dental professionals for patient-specific removable dentures and baseplates. Benefits: provides alternative to traditional denture base materials; enables local, chairside manufacturing of prosthetics. Device is non-sterile; requires post-print processing.

Clinical Evidence

No clinical data. Bench testing only. Biocompatibility testing performed per ISO 10993-1 and ISO 7405 (genotoxicity, cytotoxicity, acute systemic toxicity, sensitization, irritation). Bench testing performed per ISO 20795-1 (flexural strength/modulus, water sorption/solubility, stability, residual monomers, homogeneity, surface characteristics, porosity, color stability). All results met expected standards.

Technological Characteristics

Light-curable acrylate resin; 3D printing material. Complies with ISO 20795-1 for flexural strength, sorption, and solubility. Non-sterile. Cured via UV lamp. Available in multiple shades (e.g., Light Pink, Meharry).

Indications for Use

Indicated for the fabrication and repair of full and partial removable dentures and baseplates in patients requiring dental prosthetics.

#### Predicate Devices

Dentca Denture Base (K143033)

#### Device Description

SprintRay Denture Base consists of a curable dental acrylate resin that is designed to be used in conjunction with a scanned 3D image of a patient's teeth, and 3D printer assembly, to locally manufacture out a dental appliance in dental offices based on the clinician's judgment of patient need.

SprintRay Denture Base resin is intended exclusively for professional dental work. SprintRay Denture Base resin is offered in following shades/colors:

- Light Pink ●
- Original Pink ●
- Light Meharry ●
- Original Meharry ●
- Extra Light Pink ●
- Medium Pink ●
- Dark Pink ●

- Dark Meharry ●
- . Deep Dark Meharry

SprintRay Denture Base is designed to meet appropriate ISO standards for flexibility, sorption, and solubility to withstand prolonged use in the oral cavity. It is delivered non-sterile, and instructions are provided on cleaning the material prior to providing it to a patient. Curing is performed with a UV lamp. The appliance is then cleaned, trimmed, and verified to fit in the dental office before the patient leaves.

## Intended Use / Indications for Use

SprintRay Denture Base resin is a light-curable polymerizable resin intended to be used for the fabrication and repair, of full and partial removable dentures and baseplates. The material is an alternative to traditional denture base material.

Fabrication of dental prosthetics with SprintRay Denture Base resin requires computer-aided design and manufacturing system that includes the following components not part of the device: oral casting impression, digital denture base file created in an optical impression system, 3D printer, and curing light equipment.

## Summary of Technological Characteristics

Light-Denture Based curing of a 3D printed acrylate resin is the technological principle for both the subject and predicate devices. SprintRay Denture Base resin is poured into a 3D printer, which relies on scanned images of the patient's oral cavity to produce a dental appliance. At a high level, the subject and predicate devices are based on the following same technological elements:

- Are a pourable acrylate resin
- · Are used in conjunction with 3D printers, which rely on common 3D images to define the fabricated dental appliance
- · Are cured prior to final trimming and cleaning
- · Are used for the fabrication of orthodontic and dental appliances

The following technological differences exist between the subject and predicate devices:

- · Differences in acrylate resin material

# Performance Data

The following performance data were provided in support of the substantial equivalence determination.

#### Biocompatibility Testing

The biocompatibility evaluation for SprintRay Denture Base was conducted in accordance with the FDA Blue Book Memorandum #G95-1 and International Standard ISO 10993-1 and ISO 7405, as recognized by FDA. The battery of testing included the following tests:

- Genotoxicity
- Cytotoxicity ●
- Acute Systematic Toxicity ●
- Sensitization ●
- Irritation ●

SprintRay Denture Base is considered tissue contacting for a period longer than 30 days (a removable prosthesis).

## Bench Testing

SprintRav Denture Base was tested for conformity with the industry consensus standard ISO 20795-1. The battery of testing included the following tests:

- Flexural Strength and Modulus ●
- Water Sorption and Solubility ●
- Stability ●
- Residual Methyl Methacrylate Monomers ●
- Homogeneity ●
- Surface Characteristics
- Shape Capability, Translucency, and Polishability ●
- Freedom from Porosity ●
- Color Stability ●

In all instances, SprintRay Denture Base functioned as intended and the outcomes were as expected.

## Conclusions

SprintRay Denture Base resin is as safe and effective as its predicate device. SprintRay Denture Base has the same intended use and indication, and similar technological characteristics, and principles of operation as its predicate device. The minor technological differences between SprintRay Denture Base and its predicate devices raise no new issues of safety or effectiveness. Performance data demonstrate that SprintRay Denture Base is as safe and effective as the predicate device. Thus, SprintRay Denture Base is substantially equivalent.
