The description focuses on the mechanical components and materials of a dental abutment system, with no mention of software, algorithms, or data processing that would indicate AI/ML.
No.
The device is an abutment for a dental implant, providing support and retention for a restoration; it is not described as treating or alleviating a disease or condition.
No
The device, a Lifecore Single Tooth Abutment, is described as providing support and retention for dental restorations. Its function is to hold a prosthetic in place, not to diagnose a condition.
No
The device description explicitly lists physical components made of titanium alloy, such as abutments, screws, and healing caps, indicating it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to attach to a dental implant and support a single-tooth restoration. This is a mechanical function within the body.
- Device Description: The description details components like abutments, screws, and healing caps, all of which are physical devices used in dental procedures.
- 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.
IVD devices are specifically designed to perform tests on biological samples outside of the body. This device is a prosthetic component used directly in a surgical and restorative procedure.

Device Description
The Lifecore Single Tooth Abutment System is designed for use with an endosseous dental implant and provides support and retention for cement-retained, single tooth restorations in the mandible or maxilla. The system consists of the single tooth abutments, abutment screws, healing caps, impression posts, and associated laboratory components. Most components are packaged separately to allow the clinician to choose only those components required for each clinical situation. The Lifecore Single Tooth Abutment System has been designed to be dimensionally compatible with the Nobel Biocare CeraOne® Abutment System gold and ceramic sleeves. The single tooth abutments and healing caps are manufactured from titanium allov (Ti 6Al-4V E.L.I.).

Nonclinical Tests:
The Lifecore Single Tooth Abutment System has been tested to ensure that all design specifications have been met. Dimensional inspections are routinely performed, Electrochemical Corrosion Evaluation of Uncoupled and Coupled Implant and Restorative Alloys has been performed to determine corrosion properties when exposed to artificial saliva and to determine the galvanic corrosion properties of the Precious Alloy/CP titanium and Precious Alloy/Ti-6Al-4V galvanic couples. All have been found to be within acceptable limits.
To ensure the Lifecore Single Tooth Abutment System design is compatible with the Nobel Biocare CeraOne® Abutment System Ceramic and Gold Sleeves, the critical mating dimensions of the CeraOne abutment, ceramic, and gold sleeves were measured using a Mycrona Video Measuring Machine and micrometers. The dimensional range for each component was determined. The Lifecore Single Tooth Abutment and Single Tooth Gold Sleeve were designed to match or to be within the dimensional ranges identified.

§ 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.
