The summary describes a mechanical dental implant abutment and its performance in mechanical tests, with no mention of AI or ML.
No
A therapeutic device is used to treat or cure a disease or condition. This device is an abutment for dental implants used to retain dentures, which is a restorative function, not a therapeutic one.
No
The device, "Locator Implant Anchor," is an abutment for endosseous dental implants used to retain overdentures or partial dentures. Its intended use focuses on mechanical retention and support for dental prostheses, not on diagnosing medical conditions or diseases. The performance metrics provided (removal retention force, fatigue strength) are mechanical properties, not diagnostic indicators.
No
The device description clearly states it is an "abutment for endosseous implants," which is a physical hardware component used in dental procedures. The performance studies also focus on physical properties like removal retention force and fatigue strength.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is an "Implant Anchor abutment for endosseous dental implants" used with "overdentures or partial dentures retained in whole or in part by endosseous implants in the mandible or maxilla." This describes a device used in vivo (within the body) for mechanical support and retention of dental prosthetics.
- Device Description: The description confirms it's an "abutment for endosseous implants."
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or treatment. The performance studies focus on mechanical properties like retention force and fatigue strength, which are relevant to the device's function within the mouth, not diagnostic testing.
IVD devices are specifically designed to perform tests on biological samples outside the body to provide diagnostic information. This device's function is entirely mechanical and related to supporting dental prosthetics inside the body.

Intended Use / Indications for Use
The Locator Implant Anchor abutment for endosseous dental implants is appropriate for use with overdentures or partial dentures retained in whole or in part by endosseous implants in the mandible or maxilla.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Removal retention force was measured for both the Locator Implant Anchor and the ZAAG Implant Anchor. Mean values were 4.7 pounds (SD = .207) for the Locator Implant Anchor, and 4.2 pounds (SD = .483) for the ZAAG Implant Anchor.
Results of fatigue testing of the Angle Correction Base show that, under the most severe conditions (25 degree angled component with a 4mm gingival cuff height), after 5 million cycles of compression testing, the fatigue strength of the attachment components is still at least 175 pounds.

§ 872.3640 Endosseous dental implant.
(a)
Identification. An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy that 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 a patient's chewing function.(b)
Classification. (1) Class II (special controls). The device is classified as class II if it is a root-form endosseous dental implant. The root-form endosseous dental implant is characterized by four geometrically distinct types: Basket, screw, solid cylinder, and hollow cylinder. The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)(2)
Classification. Class II (special controls). The device is classified as class II if it is a blade-form endosseous dental implant. The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use;
(ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads;
(iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system;
(iv) The device must be demonstrated to be biocompatible;
(v) Sterility testing must demonstrate the sterility of the device;
(vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment;
(vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians;
(viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and
(ix) Documented clinical experience must demonstrate safe and effective use and capture any adverse events observed during clinical use.

Trade Name: Locator Implant Anchor Common Name: Abutment for Endosseous Implant Classification Name: Endosseous Dental Implant (accessory) 76DZE
The legally marketed device to which our firm is claiming equivalence is identified as the ZAAG Implant Anchor manufactured by Zest Anchors, Inc., and cleared for market under K934668. The predicate device is an abutment for endosseous implants which is intended for use with overdentures or partial dentures retained in whole or in part by endosseous implants in the mandible or maxilla.
The 510 (k) notification is based upon the fact that there are no significant differences between the Locator Implant Anchor (subject of this submittal) and the ZAAG Implant Anchor (predicate device) in terms of indications for use, design, and materials.
The most significant functional requirement of the devices is the value of the retentive force. Experience has shown that it should fall between 3.0 pounds and 5.0 pounds. Removal retention force was measured for both the Locator Implant Anchor and the ZAAG Implant Anchor. Mean values were 4.7 pounds (SD = .207) for the Locator Implant Anchor, and 4.2 pounds (SD = .483) for the ZAAG Implant Anchor.

Safety of the devices can be influenced by their ability to withstand occlusal forces in a divergently placed implant fixture. The Locator Implant Anchor and ZAAG Implant Anchor share the exact same Angle Correction Base which threads into a mal-aligned endosseous implant. Results of fatigue testing of the Angle Correction Base show that, under the most severe conditions (25 degree angled component with a 4mm gingival cuff height), after 5 million cycles of compression testing, the fatigue strength of the attachment components is still at least 175 pounds.
In conclusion, this 510 (k) Summary is based upon the facts drawn from the results of testing which indicate the determination of substantial equivalence between the Locator Implant Anchor (subject of this submittal) and the ZAAG Implant Anchor (predicate device).
