This is a 510(k) summary for a dental cement, not an AI/ML powered device. Therefore, many of the requested criteria regarding AI device studies are not applicable. I will address the applicable criteria based on the provided text.

2. Sample size used for the test set and the data provenance
- Sample size: Not specified.
- Data provenance: Not specified, but likely from in-house laboratory testing based on the standards cited (ISO 4049:2000, ISO 10993). This would typically be considered prospective testing for the purpose of demonstrating device performance against a standard. The country of origin is not explicitly stated beyond "Ivoclar Vivadent, Inc. 175 Pineview Drive, Amherst, NY 14228".
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. This device is a material, not a diagnostic or AI device that requires expert ground truth for its performance evaluation in the context of the reported tests. Its performance is measured against physical and chemical standards.
4. Adjudication method for the test set
Not applicable. The tests are objective measurements of physical and chemical properties based on ISO 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 is not an AI/ML powered device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an AI/ML powered device.
7. The type of ground truth used
For the performance tests (Water Absorption, Solubility, Radiopacity, Flexural Strength, Modulus of Elasticity, Compressive Strength, Shear Bond Strength), the "ground truth" or reference is the standards set forth by ISO 4049:2000. The biocompatibility "ground truth" is defined by ISO 10993. The device's performance is compared against these established material performance criteria and against the performance of its predicate device to claim substantial equivalence.
8. The sample size for the training set
Not applicable. This is not an AI/ML powered device. There is no "training set" in the context of material science evaluation for a 510(k) submission like this.
9. How the ground truth for the training set was established
Not applicable. As this is not an AI/ML powered device, there is no training set or associated ground truth establishment process in the AI sense.

Multilink Automix is used for the permanent cementation of indirect restorations where a strong bond is desired:
- Inlays, onlays, crowns, bridges and root posts made of: –
- o Metal and metal ceramics
- o All-ceramics, in particular opaque zirconium oxide ceramics
- o Composites and fibre-reinforced composites
Multilink Automix is a self-curing and self-etching luting composite system for the adhesive luting of indirect restorations made of metalceramic all-ceramic and composite. Multilink Automix is applied together with the selfetching and self-Ocuring Multilink Primer. Monobond Plus is recommended as a coupling agent to achieve a strong bond to precious and non-precious alloys, as well as to all ceramics made of zirconium and aluminum oxide and silicate ceramics.
The provided text describes the submission for MULTILINK AUTOMIX to the FDA for 510(k) clearance. The focus of the study is to demonstrate substantial equivalence to a predicate device, not necessarily to set new, absolute acceptance criteria for the new device as a standalone product based on clinical outcomes.
Here's a breakdown of the requested information based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are implicitly defined by the performance of the predicate device, Multilink (K032470), as the new device, Multilink Automix, aims to show substantial equivalence. The "acceptance criteria" for the Multilink Automix are therefore that its performance falls within an expected range relative to the predicate, demonstrating it is "substantially equivalent" and "no new issues of safety and effectiveness" persist.
| Property | UOM | Predicate Device (Multilink K032470) | Multilink Automix (Self Curing) Reported Performance | Multilink Automix (Dual Curing) Reported Performance | Acceptance Criteria (Implied: Substantially Equivalent to Predicate) |
|---|---|---|---|---|---|
| Working time (37C) | Min | 3-4 | 3-4 | -- | Within range of 3-4 min |
| Setting time | Min | 7-9 | 6-7 | -- | Within a comparable range to 7-9 min |
| Film Thickness | µm | <20 | <50 | <50 | <50 µm (Note: Higher than predicate, but still acceptable for this class of device) |
| Water Absorption | µg/mm³ | <25.0 | <40 | <40 | <40 µg/mm³ (Note: Higher than predicate, but acceptable) |
| Water solubility | µg/mm³ | <3.0 | <7.5 | <7.5 | <7.5 µg/mm³ (Note: Higher than predicate, but acceptable) |
| Radiopacity | %Al | 350 | 350 | 350 | 350 %Al (Matches predicate) |
| Flexural Strength | MPa | 90±10 | 70±20 | 110±10 | Comparable to 90±10 MPa (Self-curing slightly lower, dual-curing higher, but both within a reasonable range for equivalence) |
| Modulus of Elasticity | MPa | 5000±1000 | 3250±400 | 6000±400 | Comparable to 5000±1000 MPa (Ranges overlap sufficiently) |
| Compressive Strength | MPa | 250±20 | 240±20 | 280±20 | Comparable to 250±20 MPa (Ranges overlap sufficiently) |
| TransparencyBase (trans and Cat)Yellow and CatOpaque and Cat | % | 12±1.510±1.52±0.5 | 12±1.510±1.52±0.5 | 12±1.510±1.52±0.5 | Matches predicate values |
| Vickers Hardness | MPa | 370 | -- | 440±30 | Comparable to 370 MPa (Dual-curing is higher, which is generally positive) |
| Shear Bond StrengthDentin / 24hEnamel/ 24h | MPa | 21±223+4 | 17±518+3 | 21±223+4 | Comparable to 21±2 and 23+4 MPa (Dual-curing matches, self-curing slightly lower but potentially acceptable) |
Note: The acceptance criteria are "implied" because the document focuses on demonstrating substantial equivalence to the predicate device, meaning the new device's performance should be within an acceptable range of the predicate's performance.
2. Sample Size Used for the Test Set and the Data Provenance
The document does not explicitly state the sample sizes for each specific test (e.g., number of specimens for flexural strength tests). It only indicates that "The device was tested in accordance with ISO 4049:2000" and other standards. These standards typically specify minimum sample sizes for material property tests.
The data provenance is from Ivoclar Vivadent, Inc., which is listed as being in Amherst, NY, USA. The data is from laboratory testing performed to demonstrate material properties, and thus is considered prospective in the sense that the tests were conducted specifically for this submission, although not on live patients.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
This type of information is not applicable to this submission. The "ground truth" here is objective physical and chemical properties of a dental material, measured using standardized laboratory methods (e.g., ISO 4049:2000). It does not involve expert interpretation or clinical assessment by medical professionals to establish a truth.
4. Adjudication Method for the Test Set
This is not applicable. As explained above, the "truth" is established by laboratory measurement, not by expert consensus or adjudication.
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 is not applicable. This submission is for a dental material/device (luting composite system), not an AI-powered diagnostic or imaging device that would involve human readers or AI assistance.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This is not applicable. This is a dental material, not an algorithm.
7. The Type of Ground Truth Used
The "ground truth" for the performance data presented is derived from standardized laboratory testing and measurements of material properties (e.g., Water Absorption, Flexural Strength, Shear Bond Strength) as per ISO 4049:2000 and other relevant standards.
8. The Sample Size for the Training Set
This is not applicable. This submission is for a physical dental material, not a machine learning model that requires a training set.
9. How the Ground Truth for the Training Set Was Established
This is not applicable for the same reason as above.
