JDZygoma Dental implant is a JDentalCare implant system.

JDZygoma Dental implant System is intended to be implanted in the upper jaw arch to provide support for fixed or removable prosthetic devices in patients with partially or fully edentulous maxilla, in order to restore patient esthetics and chewing function.

The JDZygoma Implants are appropriate for immediate loading when good primary stability is achieved and with appropriate occlusal loading.

JDZygoma dental implants are implantable devices produced in commercially pure titanium, intended to be integrated in the Zygomatic bone to support prosthetic devices, such as artificial teeth, in order to restore chewing function.

The JDZygoma implant bodies are single use, gamma sterilized devices that shall be used by qualified medical personnel. The abutments are supplied non sterile and must be sterilized prior to use.

The JDZYGOMA DENTAL IMPLANTS includes 2 lines of devices with different body diameters of implants (3.9 mm and 4.3 mm) with different implant lengths:

• Diameter(mm) 3.9 Lengths (mm): 30 / 35 / 37.5 / 40 / 42.5 / 45 / 47.5 / 50 / 52.5 / 55 / 57.5 ●
• Diameter(mm) 4.3 Lengths (mm): 30 / 35 / 37.5 / 40 / 42.5 / 45 / 47.5 / 50 / 52.5 / 55 / 57.5 .

The surfaces JDZYGOMA DENTAL IMPLANTS, both 3.9 mm and 4.3 mm of diameter, is machined in the distal part of the fixture while the apical part, the threaded part, is characterized by a surface that is a SLA surface obtained through a sandblasting process followed by acid etching.

Machined surface has been analyzed form a morphological point of view using scanning electron microscope (SEM) with different level of magnification (100x, 500x, 1000x and 250x) and also performing a 3D analysis, that allow to define roughness profile with an average height of selected area (Sa) equal to 0.64 um, with a Root mean square gradient (Sdq) of 1.06 and a developed interfacial area ratio (Sdr) of 47.64%.

The abutments are made of titanium grade 5 and have the following angulations:

• . 45° 52.5° and 60°
  The connection implant / abutment is done through an internal hexagon.

The conical abutments surface is completely treated with anodic oxidation resulting in perception of yellow color.

The anodization process is performed by immersing the anodization solution and by providing an electrical voltage for a time necessary to activate the process with the material (titanium grade 5) and then performing washing process and drying the devices.

The result of this process has been evaluated from a morphological point of view using scanning electron microscope (SEM), measuring the roughness parameters and performing qualitative analysis of the chemical composition of the abutments surface with X-Ray detector considering and comparing both a non anodized abutments and the same anodized abutments in their finished forms.

These evaluations show a relatively uniform surface with characteristic textures of typical machined titanium, clean and free from significant residues or contaminants, with a morphology of the surface before and after anodization that doesn't show appreciable differences also for roughness and X-ray analysis identify a presence of only of Ti, Al, V, O, as expected.

The provided text is a 510(k) summary for the JDZygoma dental implants, which is a medical device. This type of document is a submission to the FDA demonstrating that the device is as safe and effective as a legally marketed predicate device. The information required in the prompt (acceptance criteria, study details, etc.) is typically found in performance studies used to support substantial equivalence.

Here's a breakdown of the requested information based on the provided text:

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

The document does not explicitly present a table of acceptance criteria for specific performance metrics with corresponding reported values in a pass/fail format. However, it describes several performance tests and their outcomes:

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 (Clinical): 143 JDZygoma dental implants in a total of 66 patients.
• Data Provenance: The studies were retrospective studies. The country of origin of the data is not specified in the provided text.

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)

The document does not provide details on the number or qualifications of experts used to establish ground truth for the clinical studies. It states that "Outcome measures were evaluated," but doesn't specify who performed these evaluations or their credentials.

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

The document does not describe any specific adjudication method for the clinical study outcomes.

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 to the provided document. The JDZygoma dental implant is a physical medical device (dental implant and abutments), not an AI/software device that would involve human readers or AI assistance in interpretation.

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

This section is Not Applicable for the same reasons as point 5.

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

For the clinical studies, the ground truth was outcomes data including:

• Implant/abutment success (defined by criteria for successful implant osseointegration)
• Prosthetic survival
• General postoperative complications
• Secondary outcomes: Modified Plaque Index (mPLI), modified Bleeding Index (mBI), Mucosal Seal Efficacy Evaluation (MSEE), and Zygomatic Implants Classification Level (ZICL).

8. The sample size for the training set

The document refers to retrospective studies and does not mention a separate "training set" in the context of device development or validation. The "143 JDZygoma dental implants in a total of 66 patients" represent the clinical data used for validation, not a separate training set as would be typical for AI/machine learning.

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

As there is no described "training set" in the context of AI/machine learning, this point is Not Applicable. The clinical "ground truth" (outcomes data) for the retrospective studies was established by evaluating the performance of the implants in patients post-surgically, as described in point 7.

This document is a 510(k) premarket notification decision letter from the FDA to Nobel Biocare AG regarding their Dental Implant Systems Portfolio - MR Conditional. It explicitly states that the letter covers indications for use and general controls, but does not contain information about acceptance criteria or performance studies for the device itself.

Therefore, I cannot provide the requested information for the following reasons:

1. Acceptance Criteria and Performance Data: The document is a regulatory clearance letter, not a clinical study report. It does not contain acceptance criteria for device performance, nor does it present any data from studies proving the device meets particular criteria. The letter confirms substantial equivalence to legally marketed predicate devices, which means the FDA has determined the device is as safe and effective as a previously cleared device, not that specific performance metrics were tested and met in a new study.
2. Study Details (Sample size, data provenance, experts, adjudication, MRMC, Standalone, Ground Truth, Training Set): Since no performance study data is included in this FDA 510(k) clearance letter, none of these details can be extracted. The document refers to various previously cleared predicate devices (e.g., K202452, K202344, K181869), but it doesn't describe the studies that led to their clearance.

In summary, the provided text does not contain the information necessary to describe acceptance criteria or a study proving the device meets those criteria.
