{6}------------------------------------------------
## Analysis of differences:
The indications for use statement has been clarified to remove the example related to image import from a magnetic resonance scanner as it is not possible to import data from magnetic resonance scanning equipment into the subject SIMPLANT software.
Functionality changes are implemented to improve usability:
- Scan registration is expanded to allow for soft tissue creation and for import of 3D model scans to help the user when determining the ideal implant position. The improved Virtual teeth function offers more options and flexibility to shape and position the virtual teeth. The additional "multiple implant movement" function makes it easier for a user to simultaneously alter the positions of more than one implant relative to the bone, thereby maintaining their initial positions relative to one another.
- । In the predicate device, the complete Implant library had to be downloaded for each library update. In the proposed device, a partial upload is possible, and as such, reduces the download time for the user.
- । The new feature "Immediate Smile featuring Atlantis abutments" makes it easier for the user to see which implants are compatible with customized ATLANTIS Abutments. Also, the design of this abutment can be imported and made visible in the planning file of the proposed SIMPLANT 18.
The "Occlusion tool", "Virtual occludator" and "Soft tissue simulation" functions have been removed from the software's functionality.
{7}------------------------------------------------
The website for ordering patient specific surgical guides has changed. Consequently, the proposed SIMPLANT 18 directs the user automatically to the new mySIMPLANT web page instead of to the former Online Shop for ordering the guide.
The media for delivery of the proposed device has been changed. The original software was delivered on DVD, whereas the proposed device is delivered via file download for installation.
## Summary of Software testing:
Software verification and validation was conducted to ensure the functionality and have been included to support the substantial equivalence of the subject SIMPLANT 18 software.
In principle, the software testing has consisted of testing of the software functionality containing the changes introduced since the approved predicate device SimPlant 2011 (K110300). . Software testing has been conducted in accordance with the software life cycle processes, as defined in IEC 62304.
The verification and validation testing has consisted of the following activities:
- Peer Code Review .
- Integration test .
- Internal release test .
- Smoke test •
- Formal system test ●
- Acceptance test .
- Beta test .
The results of verification and validation confirm that all user needs and performance requirements according to the design inputs are fulfilled.
#### 7. Conclusion Regarding Substantial Equivalence:
The proposed SIMPLANT 18 is software intended for use as a software interface and image segmentation system for the transfer of imaging information from a medical scanner such as a CT scanner. It is also intended as pre-planning software for dental implant placement and surgical treatment.
The proposed SIMPLANT 18 software, which is the subject of this premarket notification, has the same intended use and similar indications for use, incorporates the same technological characteristics and principles of operation as the predicate SimPlant 2011 (K110300) device. SIMPLANT 18 is tested and validated in the same way as the predicate SimPlant 2011 (K110300) device. Test data to verify the performance of the proposed SIMPLANT 18 have been included and the results of this testing confirmed the functionality and support the substantial equivalence of the proposed device SIMPLANT 18.

Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
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.
