HySil Impression Materials are addition-curing, elastomeric materials with hydrophilic properties, high tear strength, dimensional accuracy, and resistance to permanent deformation. The HySil impression materials family consists of six different viscosities (putty, heavy, mono, light. Extra-light and Bite) available in an assortment of delivery systems: standard 1:1 50 ml automix cartridges, and traditional 1:1 putty jars.
Putty, Heavy, Mono, Light and Extra-light of this proposed devices are classified into Type 0, Type 1, Type 2, and Type 3 according to ISO 4823, and Bite is classified as Dentistry - Jaw relation recording material according to DIN 13903 HySil Bite is an addition-curing silicone bite registration materials in a 50ml cartridge type to measure accurate bite. HySil Bite is suitable for bite registration as it has a short setting time, high final hardness after curing for user convenience, and less elastic deformation when eliminated.

This is a 510(k) premarket notification for a dental impression material, not an AI/ML device. Therefore, the questions related to AI/ML specific criteria (e.g., sample sizes for test/training sets, expert adjudication, MRMC studies, standalone algorithm performance) are not applicable.

The submission focuses on demonstrating substantial equivalence to predicate devices based on non-clinical performance testing and biocompatibility.

Here's the information that can be extracted from the provided text, aligning with the categories where applicable for a non-AI/ML device:

1. Table of Acceptance Criteria and Reported Device Performance

For HySil Extra Light and HySil Putty (ISO 4823 and ISO 10993 family):

For HySil Bite (DIN 13903 and ISO 10993 family):

2. Sample size used for the test set and the data provenance:

• The document implies that testing was performed on the HySil Impression Materials as the "subject device" against predicate devices.
• The exact sample sizes for each specific test (e.g., how many specimens were tested for linear dimensional change) are not explicitly stated in the provided text.
• Data Provenance: The manufacturer is Osstem Implant Co., Ltd., located in Busan, Republic of Korea. The testing was conducted as part of their 510(k) submission, suggesting it was internal testing by the manufacturer or a contracted lab. The data would be considered prospective as it was generated to support this specific regulatory submission.

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 question is not applicable as the submission is for a material, not an AI/ML device that generates diagnoses or interpretations requiring expert ground truth.

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

• This question is not applicable as this is not an AI/ML device involving human interpretation requiring 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 question is not applicable as this is not an AI/ML device. No MRMC study was performed.

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

• This question is not applicable as this is not an AI/ML device.

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

• For the physical and mechanical properties, the "ground truth" or acceptance criteria are based on recognized international standards:
  • ISO 4823 for general impression materials.
  • DIN 13903 for jaw relation recording materials (HySil Bite).
• For biocompatibility, the "ground truth" is based on ISO 10993 family standards (e.g., ISO 10993-5 for cytotoxicity, ISO 10993-10 for sensitization and irritation).
• The device performance is compared directly to the specified requirements within these standards and the reported performance of legally marketed predicate devices.

8. The sample size for the training set:

• This question is not applicable as this is not an AI/ML device. No training set was used.

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

• This question is not applicable as this is not an AI/ML device. No training set was used.
