No
The device is an attachment system for overdentures and partial dentures, serving as a component for dental prosthetics rather than providing a direct therapeutic effect.
No
The device is an attachment system for overdentures and partial dentures, designed to retain them to endosseous implants. It does not perform any diagnostic function.
No
The device description explicitly details physical components made of titanium alloy, nylon, and PEEK, which are hardware materials. The summary also discusses mechanical compatibility and engineering analysis of the abutment-implant interface, further indicating a hardware-based device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for use with overdentures or partial dentures retained by endosseous implants. This is a mechanical/prosthetic function within the body.
- Device Description: The description details the components (abutments, liners, caps) and their function in attaching dentures to implants. This is a physical attachment system.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
The device is a medical device, specifically a dental prosthetic attachment system, but it does not fit the definition of an In Vitro Diagnostic device.

Device Description
LOCATOR R-Tx implant attachment system, consists of abutments, nylon or PEEK liners and denture caps to serve in a similar function to LOCATOR as a resilient attachment for endosseous implants. All LOCATOR R-Tx abutments are made of titanium alloy and have the same coronal double ridge retention design that attaches to the overdenture component. The threaded apical end of the abutment connects to the implant and is specific to each compatible implant system and diameter. LOCATOR R-Tx is designed to accommodate a path of insertion on implants that are divergent up to 30° unless prohibited by the implant manufacturer. LOCATOR R-Tx abutments are provided with either TiCN or TiN coating and available in six cuff heights (1, 2, 3, 4, 5, and 6 mm). The abutments are provided in diameters 3.0 - 6.5 mm as shown below in the compatibility table.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The abutment-implant interface of the R-Tx abutment is verified to be compatible through either OEM signed abutment drawings, OEM implant drawings, or established compatibility demonstrated with the use of LOCATOR abutments through mutual contractual agreements with the OEM. Once the specifications and tolerances have been identified, the R-Tx abutment-implant interface is then verified through engineering analysis and documented per Zest internal procedures for Line Extensions. No additional performance testing is required as compatibility confirms that all testing (i.e., biocompatibility, sterilization, surface characterization) provided in predicate K150295 remains applicable to the new abutment-implant connection, with no impact to the risk profile of the LOCATOR R-Tx Attachment System.

Dear Marysa Loustalot:
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
1
requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 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 (OS) 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.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

VII. PERFORMANCE TESTING
The abutment-implant interface of the R-Tx abutment is verified to be compatible through either OEM signed abutment drawings, OEM implant drawings, or established compatibility demonstrated with the use of LOCATOR abutments through mutual contractual agreements with the OEM. Once the specifications and tolerances have been identified, the R-Tx abutment-implant interface is then verified through engineering analysis and documented per Zest internal procedures for Line Extensions. No additional performance testing is required as compatibility confirms that all testing (i.e., biocompatibility, sterilization, surface characterization) provided in predicate K150295 remains applicable to the new abutment-implant connection, with no impact to the risk profile of the LOCATOR R-Tx Attachment System.
CONCLUSION VIII.
The minor modifications made for implant compatibility on the LOCATOR R-Tx abutment design does not introduce a new worst case as the abutments remain tissue supported, the changes do not identify new risks, nor do the changes impact the risk profile of the device cleared under K150295. Therefore, the new abutment-implant connections and modified abutment designs identified within this Special 510(k) are substantially equivalent to those cleared in K150295.
