Intended Use
Harvest Printable Resin is indicated for the fabrication of dental bases for full removable dentures, artificial teeth, dental bite splints and guards and try-in devices, i.e., denture base and teeth. The material is an alternative to traditional heat-curable and auto-polymerizing resins and is intended for professional dental work only. This material is intended to be used by dental lab technicians and approved by licensed practitioners before being provided to the patient.
Device Description
Harvest Printable Resin is a light-cured resin developed for additive manufacturing (3D printing) of individual full denture bases, artificial teeth, bite splints and guards and try-in devices, i.e., denture base and teeth. After being utilized in a 3D stereolithographic printer to generate a dental device based on a solid model, the device is placed in a UV light curing unit for final polymerization. Fabrication using Harvest Printable Resin requires an appropriate computer-aided Design and Manufacturing (CAD/CAM) system, a digital light processing (DLP) printer, and post-processing light curing equipment. It has been optimized for use with Asiga (Max UV, Pro 4K65 and Pro 4K80) and Sprintray (Pro95 S and Pro55 S) printers and, therefore, may only be used in conjunction with these printers and their associated software systems. It is also only to be used in conjunction with Asiga (Max UV, Pro 4K65 and Pro 4K80) and Sprintray (Procure and Procure 2) curing units for post-processing. The 3D printer is not included with the device.

No
The summary describes a printable resin material and its intended use in 3D printing dental devices. There is no mention of AI or ML technology being incorporated into the resin itself or the associated manufacturing process described. The required CAD/CAM system and printer software are mentioned, but not in a way that suggests AI/ML capabilities.

No.
This device is a material (resin) used to fabricate dental devices like denture bases and bite splints, not a therapeutic device itself.

No

The device is a light-cured resin used for fabricating dental bases, artificial teeth, and bite splints, which are physical dental devices, not diagnostic tools. Its intended use is for "fabrication" and it is described as "material" for professional dental work.

No

The device is a light-cured resin material used for 3D printing dental devices. It is a physical material, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for the fabrication of dental devices (denture bases, artificial teeth, bite splints, guards, try-in devices). This is a manufacturing process for a medical device that will be used in the patient's mouth, not a test performed on a sample taken from the patient to provide diagnostic information.
  • Device Description: The device is a light-cured resin used in a 3D printing process to create physical dental devices. This is a material used in the fabrication of a medical device, not a diagnostic test kit or instrument.
  • No mention of analyzing samples: There is no indication that this device is used to analyze any biological samples (blood, urine, tissue, etc.) to provide diagnostic information about a patient's health.

IVD devices are specifically designed to be used in vitro (outside the body) to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Dear Colleen Boswell:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part

1

801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

6. Summary of Technological Characteristics with the Predicate Device

The technological characteristics of the subject Harvest Printable Resin is similar to the predicate devices, NextDent Denture/E-Denture (K162572) and E-Guard (K201173). There are no substantial technical or functional differences between the Harvest Printable Resin and the predicate devices in terms of chemical composition, function and intended use. All are light-cured resins used in a 3D printer which prints the shape determined by a 3D stereolithographic drawing. See Table 1 below for technological characteristics and comparisons of the denture relining, rebasing resin, plastic denture teeth resin and prescription mouthguard and splints resin.

7. Performance Data

Biocompatibility Testing

The biocompatibility evaluation for the Harvest Printable Resin was conducted in accordance with ISO 7405:2018 Dentistry - Evaluation of biocompatibility of medical devices used in dentistry. Annex A. and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process" as recognized by FDA. The biocompatibility testing included the following tests:

    1. Cytotoxicity
    1. Sensitization
    1. Intracutaneous Reactivity

The biocompatibility testing conducted demonstrates adequate biocompatibility for the Harvest Printable Resin.

ISO 20795-1 & -2 Testing

Testing according to ISO 20795-1:2013 Dentistry - Base polymers, Part 1: Denture base polymers and ISO 20795-2:2013 Dentistry - Base polymers, Part 2: Orthodontic base polymers was performed on the Harvest Printable Resin and as compared to the predicate devices, it is substantially equivalent to the devices and met the physical/mechanical properties of the standard.

Clinical Studies

No human clinical testing was conducted to support substantial equivalence.
