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 available 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. {1}------------------------------------------------ Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

KeyPrint KeySplint Hard #### DEVICE DESCRIPTION The Subject device is a light-cured methacrylate-based resin used in 3D printers to produce dental mouthguards, nightguards, splints, and repositioners. The Subject device is a viscous solution consisting of methacrylate-based resins, photo initiators and pigment. The Subject device is used by a dental professional (dentist or dental technician) for the additive Computer-Aided Manufacturing (CAM) of dental mouthguards, nightguards, splints, and repositioners. There are two models of {5}------------------------------------------------ the Subject device which are referred to as FREEPRINT® splintmaster flex and FREEPRINT® splintmaster taff with slightly different material properties for either a more flexible or rigid final product. The Subject device resin is used within a validated manufacturing workflow to create the intended dental device. Dental devices fabricated using the Subject device are one-time use, prescription-only devices. Methacrylates are known materials, commonly used in the dental industry for fixed and removable prosthetic devices due to their physical-chemical, mechanical, and biocompatible properties. ## EQUIVALENCE TO MARKETED DEVICE The Subject device is highly similar to the Predicate devices with respect to Indications for Use and technological principles. The comparison tables below compare the Indications for Use and Technological Characteristics of the Subject and Predicate devices. | Device | Indications for Use Statement | |----------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Subject Device

The lack of the secondary EBI Product Code does not impact or change the intended use of the Subject device. Intended Use - The Subject and Predicate devices are Highly Similar in their intended use, effectively conveying the same intended use with slight differences in wording. Biocompatible/Rx/Sterility - The Subject and Predicate devices share the same designations. Chemical Composition - The Subject and Predicate devices are the same in they are both UV-light cured liquid methacrylate-based resins with photo initiator(s). Slight differences in chemical composition do not change the intended use of the Subject and Predicate devices to be used in the fabrication of dental mouthguards, nightguards, splints, and repositioners. The Subject device has demonstrated suitability for intended use through material non-clinical performance testing. Polymerization (Curing) Method/Equipment - The Subject and Predicate devices are the same in that they are both light-cured polymer resins encompassing the same range of curing wavelengths and used with validated 3D printer/post-curing workflows. Any differences in the curing light wavelength does not change the intended use of the Subject and Predicate devices to be used in the fabrication of the intended dental devices. Performance Testing – The Subject and Predicate devices were tested by their respective sponsors to the same ISO 20795-2 material property standard, meeting most of the standard. Comparative testing was performed with the Subject and Predicate devices to ISO 20795-2, ISO 527-1 and ISO 179-1 which demonstrated similar performance for the ISO 20795-2 properties as well as tensile strength, elongation at break and Charpy Impact. {7}------------------------------------------------ Biocompatibility - The Subject and Predicate devices are similar in the standards and biological endpoints the devices were evaluated to. Slight differences in the standards and tested endpoints do not change the intended use of the Subject and Predicate devices. Overall, the Technological Characteristics of the Subject and Predicate devices are the Same or Highly Similar. Technological differences between the Subject and Predicate devices have been evaluated through non-clinical performance testing. The results of the tests performed show that Subject device meets the requirements mentioned in the applicable standards and confirm that the Subject device performs similarly to the Predicate devices. # CLINICAL AND ANIMAL TESTING The performance of methacrylate-based polymer resins in the clinical environment has been well established. No clinical or animal testing data is included in this submission. ## NON-CLINICAL PERFORMANCE TESTING Validation of the manufacturing process and compatible equipment was performed demonstrating consistency of the process output with that of the process input. Physical property testing was performed on the Subject device to ISO 20795-2, Dentistry — Part 2: Orthodontic base polymers. Performance testing on the Subject device was performed for the surface finish, shape capability, color, freedom from porosity, flexural modulus, maximum stress intensity factor, total work fracture, water sorption, water solubility endpoints identified in ISO 20795-2. Comparative material property testing was also performed with the Predicate devices to these endpoints demonstrating similar performance. A biological evaluation was performed on the Subject device. Chemical characterization was performed to ISO 10993-18 with a risk assessment performed according to ISO 10993-17 and ISO/TS 21726. Biocompatibility testing was performed on the Subject device according to ISO 10993-1:2018 and ISO 7405:2014 according to the standards listed in the Technological Characteristics comparison table above. An MRI safety assessment was performed on the Subject device to support MR Safety labeling as required by the FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment". Non-clinical performance testing of the Subject device met the acceptance criteria for each validation and test described above. This non-clinical performance testing demonstrates that the Subject device is suitable for intended use. ## CONCLUSION Overall, the Indications for Use statements for the Subject and Predicate devices are highly similar differing only in device name and slightly in use duration. Overall, the Technological Characteristics of the Subject device are the same or highly similar to the Predicate device with any differences mitigated through nonclinical performance testing. Overall, these similarities between the Subject and Predicate devices, support a determination of substantial equivalence. --- **Source:** [https://fda.innolitics.com/device/K232448](https://fda.innolitics.com/device/K232448) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
