(84 days)
MIS dental implant system is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore masticatory function. When a one-stage surgical procedure is applied, the implant may be immediately loaded when good primary stability is achieved and the occlusal load is appropriate.
Narrow implants (Ø3.30mm) are indicated for use in surgical and restorative applications for placement only in the mandibular central, lateral incisor and maxillary lateral incisor regions of partially edentulous jaws, to provide support for prosthetic devices such as artificial teeth. Mandibular central and lateral incisors must be splinted if using two or more narrow implants adjacent to one another.
The subject devices, MIS Implants, are supplied sterile and packaged together with a cover screw which can be connected to the implant during the initial healing period after implant placement.
The implants and cover screws are made of titanium alloy (Ti-6Al-4V ELI complying with standard ASTM F136-13 - Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant). The design and material of the implants and cover screws remain unchanged since most recently cleared 510(k).
The implants are also used with a wide range of previously cleared abutments which are sold separately.
This document is a 510(k) clearance letter for dental implants, not an AI/software as a medical device (SaMD) submission. Therefore, it does not contain the information requested regarding acceptance criteria and study proving device meets acceptance criteria for an AI/SaMD product.
The document discusses dental implants and their physical and material characteristics, regulatory classifications, predicate devices, and performance testing for mechanical properties, sterility, and packaging. The "Performance Data" section specifically mentions "Hydrophilicity testing" for "wet-packed implants" and other physical tests, but none of these relate to AI/SaMD performance metrics like sensitivity, specificity, or reader studies.
Therefore, I cannot provide a table of acceptance criteria, sample sizes for test sets, expert qualifications, or details on MRMC studies, standalone performance, or ground truth establishment relevant to an AI/SaMD product based on the provided text.
The prompt asks for information that this type of medical device submission (dental implants) would not typically include.

Dear Melanie Avila:
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 (the 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 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.

Performance Data
Summary of non-clinical tests conducted for determination of substantial equivalence:
Hydrophilicity testing, which is an internal test method, was performed per sessile drop test, on the proposed implants to support substantial equivalence and to demonstrate the minor changes to the primary packaging from the predicate device do not impact the requirement of a super-hydrophilic surface for the wet-packed implants over the shelf life of the device.
In all instances, the subject device functioned as intended and all test results observed were as expected.
The testing generated strong evidence that the subject devices are found to be substantially equivalent to the predicate device
The following testing and analysis were leveraged from the predicate (K241692) and reference devices:
- Biocompatibility Testing per ISO 10993-1, Biological evaluation of medical devices
- Sterilization per ISO 11737-1:2018 Sterilization of health care products Microbiological methods
- Transportation Testing per ASTM D4169-22 - Standard Practice for Performance Testing of Shipping Containers and Systems and ASTM D4332-22 - Standard Practice for Conditioning Containers, Packages, or Packaging Components for Testing
- Shelf Life Testing per ISO 11607-1:2019 Packaging for terminally sterilized medical devices-Part1: Requirements for materials, sterile barrier systems and packaging systems, ASTM F 1929-15 Standard test method for detecting seal leaks in porous medical packaging by dye penetration, ASTM F88/F88M-23 Standard Test Method for Seal Strength of Flexible Barrier Materials, ASTM F2096-11 (Reapproved 2019) Standard Test for detecting gross leaks in packaging by internal pressurization (Bubble test), ASTM F1980-21 Standard Guide for Accelerated Aging of Sterile Barrier Systems for Medical Devices, and ISO 11737-2:2019(E) Sterilization of health care products – Microbiological methods –Part 2: Tests of sterility performed in the definition, validation and maintenances of a sterilization process
- Fatigue Testing per ISO 14801:2016 Dentistry - Implants – Dynamic fatigue tests for endosseous dental implant and FDA's Guidance - Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments
- Surface Modification Characterization by SEM (scanning electron microscope) to demonstrate surface cleanliness
- MR Conditional Testing per Magnetically induced displacement force, according to ASTM F2052-21, Standard test method for measurement of magnetically induced displacement force on medical devices in the magnetic resonance environment, Image Artifact, according to ASTM F2119-07 (2013), Standard test method for evaluation of MR image artifacts from passive implants, and RF Induced Heating Simulation using Computational modeling and simulation (CM&S)
Clinical testing was not necessary to demonstrate equivalence.
Conclusions
The subject devices, MIS Implant Systems and the predicate device have the same intended use and similar indications for use. MIS Implant Systems and the predicate device have the similar technological characteristics and principles of operation. The proposed change for the primary and secondary packaging of the implant and cover screw is similar to the primary packaging and the same as the secondary packaging for the Lynx Conical Connection Implant System, cleared under 510(k) K241692.
No other changes have been made to the implant design, technological characteristics or intended use since the most recently cleared 510(k) for each of the MIS Implants Systems.
The minor differences in primary packaging do not present different questions of safety or effectiveness than the predicate device because the subject device functions to the same packaging performance specifications as the predicate device. Thus, the primary packaging for the subject device, MIS Implant Systems, is substantially equivalent to the primary packaging of the predicate device.
The subject device is substantially equivalent as the predicate device.
