The implants are provided in two different surfaces: Neoporos: Sand blasted and acid etched, and Acqua: Hydrophilic surface aggregated to the rough surface obtained by double treatment: abrasive blasting and acid subtraction.
The Helix Short Implant Titanium Base abutments is used as two-piece abutment, where the base is premanufactured from titanium alloy and the top half is created via burn out coping or a digital workflow with CAD/CAM at a validated milling center. The final top half can be created from Ticon, Coron, Zerion LT, IPS e.max, or PMMA. The top half and base pieces are cemented together to form the final abutment.

AI/ML Overview

Here's an analysis of the acceptance criteria and supporting studies for the Neodent Implant System - Helix Short Implant System, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The FDA 510(k) summary does not explicitly present a table of specific numerical acceptance criteria alongside reported performance for each test. Instead, it describes what was tested and states that the results "met the acceptance criteria" or demonstrated "equivalent performance." We can infer the general acceptance criterion from the study descriptions.

Acceptance Criteria (Inferred)	Reported Device Performance
Mechanical Testing:
Dynamic Fatigue Test (per ISO 14801): Equivalent fatigue strength to predicate devices.	The tested subject devices exhibit a level of performance equivalent to that reviewed for the predicate devices.
Torsion Test (static torsional loading): Meet acceptance criteria.	The results met the acceptance criteria.
Insertion Test: Evaluate insertion torque in various bone types.	Performed to evaluate the insertion torque of the Helix Short System when it is inserted in bones type I, II, III, and IV. (No explicit "met criteria" statement, but implied by successful evaluation).
Implant Surface Area Simulation and Pull Out Test: Demonstrate acceptable BIC rate and pull out resistance.	Results demonstrated that the subject devices, despite having a slightly smaller surface area than the reference devices, presented a higher BIC rate and pull out resistance upon placement. Thus, the subject devices exhibit a level of benchtop performance equivalent to that reviewed for the reference device.
MR Compatibility Testing:
Not configure a new worst case compared to reference devices, allow safe scanning under established parameters.	An assessment was made to demonstrate that the subject devices do not configure a new worst case and can be represented by the previously conducted studies reviewed for reference devices, since both have the same raw material and similar dimensions. The subject devices are therefore MR conditional devices and a patient treated with the subject devices can be safely scanned observing the parameters previously established per reference devices.
Surface Treatment:
Identical or similar chemical processes to predicate/reference devices to achieve roughness.	The surface treatments applied to subject devices are identical to these applied and previously evaluated for primary predicate devices. Although some reference devices have a surface with different nomenclature, the chemical processes applied to the surface are similar to create the roughness surface. Acqua implants are submitted to an additional step in order to increase their hydrophilicity, as already cleared for primary predicate device.
Sterilization Validation:
Implants (Gamma Irradiation): Minimum Sterility Assurance Level (SAL) of 1 x 10^-6.	A minimum Sterility Assurance Level (SAL) of 1 x 10^-6 has been validated based on ISO 11137-1 and ISO 11137-2.
Abutments (Ethylene Oxide): Minimum Sterility Assurance Level (SAL) of 1 x 10^-6.	A minimum Sterility Assurance Level (SAL) of 1 x 10^-6 has been validated based on ISO 11135-1.
Endotoxin Testing (LAL):
Meet pyrogen limit specifications (acceptance criteria for endotoxin levels).	Subject devices meet the acceptance criteria for endotoxin levels as well as the primary predicate and reference devices.
Shelf Life Validation:
Packaging integrity maintained; established expiration date.	The shelf life for devices provided sterile is 5 years, except Helix Short Acqua Implants that have a shelf life of 4 years. The expiration date was determined considering product integrity and packaging tests.
Biocompatibility:
No new issues compared to predicate/reference devices.	No new issues of biocompatibility are raised for the subject devices when compared to primary predicate and reference devices. Therefore, no additional biocompatibility testing was required.

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the numerical sample size for the test sets in the mechanical, MR compatibility, or other in-vitro studies. It refers to "tested subject devices" or "representative samples."

Data Provenance: The studies described (mechanical testing, MR compatibility, surface treatment, sterilization, endotoxin, shelf life, biocompatibility) are all benchtop/laboratory studies (in vitro). There is no mention of human subject data, animal data, or clinical retrospective/prospective data for these specific performance criteria. The manufacturer is JJGC Indústria e Comércio de Materiais Dentários S.A. (dba Neodent) based in Curitiba, Paraná, Brazil.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

Not applicable. As these are benchtop/laboratory performance studies, "ground truth" is established by adherence to recognized standards (e.g., ISO 14801, ISO 11137, ISO 11135, ISO 10993) and scientific methods, not by expert consensus in the typical sense for clinical data.

4. Adjudication Method for the Test Set

Not applicable. Adjudication methods like 2+1 or 3+1 are typically used for interpreting clinical images or patient outcomes, not for objective benchtop performance data against engineering standards.

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

Not applicable. This device is an endosseous dental implant system, which is a physical medical device, not an AI-powered diagnostic or assistive tool. Therefore, MRMC studies involving human readers and AI assistance are not relevant.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Not applicable, as this is a physical medical device, not an algorithm.

7. The Type of Ground Truth Used

The "ground truth" for the performance claims is based on:

Adherence to International Standards: Performance measured against specifications outlined in standards like ISO 14801 (dynamic fatigue), ISO 11137 and ISO 11135 (sterilization), ISO 10993 series (biocompatibility).
Benchtop Test Results: Direct measurements and observations from the mechanical, physical, chemical, and biological laboratory tests performed on the device.
Comparison to Predicate Devices: Performance is frequently established by demonstrating equivalence or superiority to already legally marketed predicate devices, which serve as a benchmark.

8. The Sample Size for the Training Set

Not applicable. This is a physical medical device. The concepts of "training set" and "validation set" are primarily used for machine learning and AI, not for the regulatory approval of physical implants based on benchtop testing.

9. How the Ground Truth for the Training Set Was Established

Not applicable for the same reasons as point 8.
