# Comment 1
The Subject Device is used for single-unit restorations only, and the Primary Predicate Device (K234112) can be used for single-unit and multi-unit restorations. The Primary Predicate Device override the Subject Device.
The difference do not alter the intended use of the device nor do they affect the safety and effectiveness of the device relative to the predicate.
The Subject Device, in contrast to the Reference Device (K193425) which can be used for single and multiple tooth restorations, is used only for single tooth restorations. Therefore, the type of restoration for the Subject Device is within the restoration type of the Reference Device.
# Comment 2
Subject Device Diameter ranges from 4.0-6.5mm, Primary Predicate Device(K234112) ranges from 3.3-6.0mm.
Transgingival height range of Subject Device(1-5mm) exceeds the Primary Predicate Device((0.5-4.0mm).
Primary Predicate Device's post height (4-13mm) contains post height range of the Subject Device (4-12mm).
Primary Predicate Device and Subject Device have the same abutment angle range.
There are slight differences in Abutment Design Parameters for the Subject Device, Primary Predicate Device. According to ISO 14801: 2016 Dentistry - Implants - Dynamic loading test for endosseous dental implants, the worst-case static fatigue test and dynamic fatigue test were performed on dental implants connected with the Subject Device. The test results show that the worst-case scenario of the Subject Device has sufficient strength for the intended clinical application. Therefore, slight differences in Abutment Design Parameters do not affect the intended use and do not adversely affect the safety and effectiveness of the Subject Device.
Compared with Reference Device (K193425), Subject Device has the different post height and transgingival height. Subject Device is within the post height range of Reference Device; Subject Device is outside the transgingival height range of Reference Device.
Abutments made of Pre-milled Blank are designed according to the patient's condition. We performed static fatigue tests and dynamic fatigue tests in accordance with ISO 14801:2016 Dentistry - Implants - Dynamic loading test for endosseous dental implants, static
{12}
fatigue test and dynamic fatigue test for the worst-case scenario. The test results show that the worst-case scenario of the Subject Device has sufficient strength for the intended clinical application.
Therefore, differences in Abutment Design Parameters do not change the intended use of the device and do not raise safety effectiveness issues.
## Comment 3
The material of Subject Device abutment is Ti-6AL-4V, screw’s material is Ti-6AL-4V ELI. The material of Primary Predicate Device (K234112) is Ti-6AL-4V ELI.
Both Ti-6AL-4V and Ti-6AL-4V ELI are common fabrication materials for abutment and implant with a long history of clinical use. According to ISO 14801:2016 Dentistry - Implants - Dynamic loading test for endosseous dental implants, the worst-case static fatigue test and dynamic fatigue test were performed on dental implants connected with Subject Device. The test results show that the worst-case scenario of the Subject Device has sufficient strength for the intended clinical application. Therefore, Subject Device is made of the same material as the commercially available products, both of which are titanium alloys, so the materials do not adversely affect the safety and effectiveness of the Subject Device.
The abutment material of Subject Device is Ti-6AL-4V, screw’s material is Ti-6AL-4V Eli, and Reference Device’s (K193425) material is Ti-6AL-4V Eli.
Both Ti-6AL-4V and Ti-6AL-4V ELI are common fabrication materials for abutment and implant with a long history of clinical use. According to ISO 14801:2016 Dentistry - Implants - Dynamic loading test for endosseous dental implants, we performed the static fatigue testing and dynamic fatigue testing of worst-case abutments made of Subject Device. The test results indicate that the worst case of the Subject Device has sufficient strength for the intended clinical application.
Therefore, differences in materials do not change the intended use of the device and do not raise questions of safety and effectiveness.

# Substantial Equivalence Conclusion:
The corresponding data show that the technical characteristics of the Subject Device and the Predicate Device(K234112) are basically identical. The minor difference between the Subject Device and the Predicate Device(K234112) is the difference in the compatible implant systems, but we compare the similarity of the devices rather than the compatibility of the implant systems, so it does not affect the intended use.
We have also analyzed the compatibility of our products with the OEM implants, and the results show that our products are compatible with the OEM implants, and we have taken effective measures to ensure that our products maintain continuous compatibility with the appropriate OEM implants.
Based on the above, we consider the Subject Device and the Predicate Device(K234112) to be essentially equivalent.
Subject Device is as safe and effective as the reference device (K193425) when used as instructed by knowledgeable and trained dental personnel. The product is identical to its reference device (K193425) concerning to the indications for use.
The corresponding data show that the technical characteristics of the Subject Device and the reference device (K193425) are basically identical.

1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
