Intended Use

The Z7 Zirconia Implant System is intended for surgical placement in the patient's upper and lower jaw to provide support for prosthetic devices, such as artificial teeth and in order to restore the patient chewing function. The implants are indicated for immediate loading when good primary stability is achieved and with appropriate occlusal loading.

The ø3.7 mm reduced diameter implants are recommended for central and lateral incisors only.

Device Description

The Z7 Zirconia Implant System is an integrated system of endosseous dental implants (Z7 Zirconia Implant One Piece) and PEEK prosthetic parts. The Z7 Zirconia Implant One Piece are yttria stabilized tetragonal zirconia (Y-TZP) dental implants composed of a One Piece, monotype implant with an integrated abutment. The implant is manufactured via a ceramic injection molding with the macro and micro surface characteristics of the implant directly structured in the mold. The implant body portion is configured to extend into the bone and osseo-integrate with the alveolar bone. The neck should be positioned 1.8mm above the bone. The implants come in corresponding diameters of 3.7 and 4.3 mm.

AI/ML Overview

The provided text describes the Z7 Zirconia Implant System, a dental implant device, and its compliance with FDA requirements for substantial equivalence to a predicate device. However, the information you've requested regarding acceptance criteria and study details in the context of an AI/ML device is not present in this document.

The document is a 510(k) clearance letter for a medical device manufactured from Zirconia (an endosseous dental implant), not an AI/ML-driven medical device. Therefore, it does not contain information about:

  • Acceptance criteria for AI performance (e.g., sensitivity, specificity, AUC)
  • Sample size for test sets in an AI context
  • Data provenance for AI training/testing
  • Number/qualifications of AI ground truth experts
  • Adjudication methods for AI ground truth
  • MRMC studies for AI assistance
  • Standalone AI algorithm performance
  • Type of ground truth used for AI
  • Training set sample size for AI
  • Ground truth establishment for AI training

The performance testing summarized in the document (Page 7) is related to the physical and material properties of the dental implant itself:

  • Material Performance Testing: Per ISO 13356:2015 for Yttria-stabilized tetragonal zirconia (Y-TZP).
  • Fatigue Testing: Per ISO 14801:2016 for dynamic loading of endosseous dental implants.
  • Implant Surface Roughness and Chemical Analysis Validation: Through 3D Scanning Electron Microscope (SEM) Imaging and Energy Dispersive Spectrometry (EDS Analysis).
  • Biocompatibility: According to ISO 10993-1 and ISO 10993-5 (cytotoxicity).
  • Endotoxin Testing: Following USP and USP.
  • Sterilization Validation: Per ISO 11135:2014 (Ethylene Oxide) and ISO 17665 (Moist Heat) for sterility assurance level (SAL) of 10^-6.
  • Shelf-Life Validation: Accelerated aging followed by real-time aging.

For these physical device tests, all results are reported as "PASS" and "Device met all predetermined acceptance criteria" or "Substantially equivalent fatigue strength to reference device."

To reiterate, this document does not contain the information you are looking for regarding AI/ML device acceptance criteria and study details.

§ 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.
