The TOV Dental Implant System are endosseous implants intended to be surgically placed in the upper or lower jaw arches to provide support for prosthetic devices, such as an artificial tooth, in order to restore patient's esthetics and chewing function. Implants are intended for single or multiple unit restorations on splinted or non-splinted applications. Maer, Ragil and TCX are intended for immediate loading when good primary stability is achieved, and with appropriate occlusive loading. These implants can also be used for loading after a conventional healing period. Ragil 3.3 implants are intended to replace a lateral incisor in the maxilla and/or a central or lateral incisor in the mandible. Mandibular central and lateral incisors must be splinted if using two or more 3.3 implants adjacent to one another.
The TOV Dental Implant System contains 2 designs of internal hex implants and various types of abutments as described below as well as 1 design of conical implant with NP and RP platforms and abutments corresponding to both platforms. All devices are made from Ti-6AL-4V ELI unless otherwise noted. The implants have a grit blasted and acid etched surface. Conical abutments need to match the implant platform of narrow or regular. No abutments other than UCLA abutments are intended to be modified by the user.
Maer implants are tapered internal hex implants with more tightly spaced flat edge threads at the top and wider spaced flat edge threads in the lower tapered section. Maer comes in 3.5, 3.75, 4.2, 5.0 and 6.0 mm diameter with lengths of 8, 10, 11.5, 13, and 16mm in 6.0mm diameter).

The provided text describes a 510(k) premarket notification for the "TOV Dental Implant System" and compares it to predicate devices to establish substantial equivalence. It does not contain information about a study proving the device meets specific acceptance criteria in the context of an AI/ML medical device. As such, most of the requested fields cannot be populated from the provided document.
The document primarily focuses on demonstrating the substantial equivalence of the TOV Dental Implant System to existing predicate devices based on design, materials, indications for use, and mechanical performance (fatigue testing). It confirms biocompatibility (cytotoxicity, skin sensitization, irritation), sterilization, and packaging stability, which are standard tests for such devices, rather than clinical performance studies.
Here's an attempt to answer the questions based on the available information:
1. A table of acceptance criteria and the reported device performance
The document mentions "Sufficient run out load for their intended use" as the performance criteria for ISO 14801 Fatigue Testing for all devices (TOV Dental Implant System, OsseOne Dental Implant System, and Surgikor Dental Implant System). Specific numerical acceptance criteria or reported performance values (e.g., in Newtons or cycles) are not provided in this summary.
| Acceptance Criteria | Reported Device Performance |
|---|---|
| ISO 14801 Fatigue Testing | Sufficient run out load for their intended use |
| Cytotoxicity (ISO 10993) | Passed |
| Skin Sensitization (ISO 10993-10:2021) | Passed |
| Irritation (ISO 10993-23:2021) | Passed |
| Steam Sterilization (ISO 17665-1) | Passed |
| Bacterial Endotoxin (ANSI/AAMI ST72:2019, USP ) | Passed |
| Gamma Irradiation (ISO 11137-2) | Passed |
| Package Testing (ASTM D999-08, ASTM F3039-13, ASTM D5276-98) | Passed |
| Shelf Life Testing (ASTM F1929-12, ASTM F1980-07) | Passed |
| Post Surface Treatment Cleanliness (Organic carbon, hydrocarbons, SEM/EDX) | Within limits based on relevant standards |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not provided in the document. The document describes mechanical and biological safety testing, which typically use laboratory samples, not human patient test sets.
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 is not applicable as the device is a dental implant system (hardware), not an AI/ML diagnostic or image analysis tool. Ground truth in this context typically refers to objective measurements in material science or toxicology, not expert interpretations of clinical data.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable for a dental implant system.
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 for a dental implant system.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable for a dental implant system.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the tests conducted (fatigue, cytotoxicity, etc.), the "ground truth" would be established by the physical and chemical properties of the materials, the mechanical limits defined by ISO standards, and the biological responses observed in laboratory tests (e.g., cell viability, immune response). There is no "expert consensus" in the clinical sense for this type of device's performance validation.
8. The sample size for the training set
Not applicable, as this is not an AI/ML device.
9. How the ground truth for the training set was established
Not applicable, as this is not an AI/ML device.

(vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment;
