The prosthetic restorations used are single crowns, fixed partial or full dentures, which are connected to the implants through the corresponding components.

The Ø3.3 mm reduced diameter implants are recommended for central and lateral incisors only.

The Straumann® PURE Ceramic Implant Protective Cap is intended to protect the Straumann® PURE Ceramic Implant (Monotype) during the healing phase after implant placement for up to 6 months.

Temporary copings are intended to serve as a base for temporary crown or bridge restoration for the Straumann® PURE Ceramic Implant (Monotype) for up to 30 days.

Device Description

The Straumann® PURE Ceramic Implant (Monotype) is made of 100% yttrium-stabilized zirconia. The endosteal region presents macro- and micro-roughness to support osseointegration (ZLA® surface). The implant has a 1.8 mm high machined neck. The implant features a monotype design where the ceramic abutment for final restoration is already built in. Straumann® PURE Ceramic Implant (Monotype) prosthetic components are identified with RD (Regular Diameter) corresponding to the neck diameter of 4.8 mm, and ND (Narrow Diameter) corresponding to the neck diameter of 3.5 mm.

The Protective Caps are manufactured from polyetheretherketone (PEEK Classix).

The temporary copings are manufactured from polymethylmethacrylate (PMMA).

AI/ML Overview

This document is a 510(k) premarket notification from the FDA, approving the Straumann® PURE Ceramic Implants. It details the device, its intended use, and substantial equivalence to predicate devices, but it does not describe a study that validates the device against acceptance criteria in the way a clinical trial or performance study for an AI/diagnostic device would.

The "acceptance criteria" mentioned in the document refers to the success rate of the implant in a clinical study, which is a different type of acceptance criteria than what would be presented for an AI device.

Let's break down what information is available based on your request and what is not available for a device like this.

1. A table of acceptance criteria and the reported device performance

For an AI/diagnostic device, acceptance criteria would typically involve metrics like sensitivity, specificity, AUC, etc., compared against predefined thresholds. For this dental implant, the primary "acceptance criterion" mentioned is the clinical success rate.

Acceptance Criteria (Clinical Success)Reported Device Performance (Clinical Study)
Exceeded 85% survival rate in the protocol97.6% survival rate at two years (among 41 ITT patients with complete follow-up)

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

  • Sample Size for Test Set (Clinical Study): 41 ITT (Intent-To-Treat) patients with complete follow-up through two years.
  • Data Provenance: Not explicitly stated in terms of country of origin. The study appears to be a prospective clinical follow-up as it refers to patients' survival to at least two years.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This section is not applicable to this type of device and study. For an implant, "ground truth" would be the patient's clinical outcome (survival, successful integration, etc.), not an expert's interpretation of an image or a condition.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This section is not applicable. Adjudication methods like 2+1 (two readers agree, third adjudicates disagreement) are used for diagnostic interpretations, not for direct clinical outcomes of an implant. The outcomes (survival) are directly observed.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This section is not applicable. This is not an AI or diagnostic device, so there is no concept of human readers or AI assistance.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This section is not applicable. This is not an AI algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

  • Type of Ground Truth: Outcomes data (specifically, implant survival/success at two years).

8. The sample size for the training set

This section is not applicable. This is not a machine learning or AI device that requires a training set. The clinical study investigated the implant's performance directly.

9. How the ground truth for the training set was established

This section is not applicable for the same reason as point 8.

1.7 Technological Characteristics

The Straumann® PURE Ceramic Implant is a one-piece monotype implant and therefore does not have an internal connection. Table 4 below provides for a comparison of key technological characteristics and indications between the Straumann® PURE Ceramic Implant and the primary predicate device. The indications are substantially equivalent to the primary predicate, as any differences relate to placement limitation due to reduced diameter implant size and the addition of protective cap and temporary coping device components.

1.8 Performance Testing

Dynamic fatigue, static strength, insertion torque and surface characterization tests were conducted according to the FDA guidance document "Guidance for Industry and FDA Staff – Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments" and showed that the Straumann® PURE Ceramic implants were equivalent to the predicate devices. Specifically, the fatigue strength of the Ø3.3 mm Straumann® PURE ceramic implant was equivalent to the Ø3.6 mm predicate device's fatigue strength. The insertion torque values of the Straumann® PURE Ceramic Ø3.3 mm implant were

{8}------------------------------------------------

measured and compared to the values of a predicate reference device (Straumann® NNC implant, K111357).

MRI testing was performed to support the MRI statements in Straumann® PURE Ceramic labeling.

The Straumann® PURE Ceramic Implants are manufactured from yttrium-stabilized zirconium oxide (Y-TZP). The material conforms to ISO 13356:2008, Implants for surgery – Ceramic materials based on yttria-stabilized tetragonal zirconia (Y-TZP). In addition to prior proven biocompatibility of implant material used, including a toxicological evaluation report and conformance to ISO13356, the following testing was performed:

  • Cytotoxicity according to ISO 10993-5:2009, Biological evaluation of medical devices -. Part 5: Test for in vitro cytotoxicity.
  • . Chemical Analysis (organic and inorganic) according to ISO 10993-18:2009, Biological evaluation of medical devices – Part 18: Chemical characterization of materials.
  • . A rabbit study comparing unaged ceramic implants with aged implants.

All of the testing above, along with a literature review, confirmed the biocompatibility of the Straumann® PURE Ceramic implants.

Sterilization validation of the Straumann® PURE Ceramic implants, in accordance with DIN EN 556-1:2002 (equivalent to ANSI AAMI ST67:2011), Sterilization of medical devices – Requirements for medical devices to be designated "STERILE" – Part 1: requirements for terminally sterilized devices, was completed. The sterilization process for the provisional components as recommended in labeling was also validated according to applicable recommendations in the FDA Guidance document "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling, issued on March 17, 2015". Straumann performed accelerated and real time aging testing to support the labeled shelf life.

Clinical study results support the equivalence of the Straumann® PURE Ceramic implants to predicate devices. Among the 41 ITT patients with complete follow-up through two years, 40 survived to at least two years (point estimate of 97.6%), which exceeded the acceptance criteria of 85% in the protocol.

Conclusion 1.9

The documentation submitted in this premarket notification demonstrates that the Straumann® PURE Ceramic Implants are substantially equivalent to the predicate devices.

§ 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.
