Device Story
Elos Accurate® Hybrid Base™ is a two-piece dental abutment system; consists of a titanium alloy base and a patient-specific zirconia superstructure. Used by dental clinicians and laboratories to restore chewing function. Input: digital scan data from intra-oral scanners. Transformation: CAD software (3Shape Abutment Designer™) uses digital library files with predefined design limits (min wall thickness 0.5mm, max angulation 20°) to design the superstructure; CAM software and milling units manufacture the zirconia component. Output: final assembled abutment/superstructure unit. The base is attached to the implant via a prosthetic screw; the zirconia top is cemented to the base. The device is delivered non-sterile; requires sterilization at the clinic before placement. Benefits include patient-specific esthetic restoration and compatibility with various implant platforms. The system ensures design integrity by preventing users from exceeding validated design limits within the software.
Clinical Evidence
Bench testing only. Evidence includes fatigue testing per ISO 14801, dimensional analysis for implant compatibility, and sterilization validation (ISO 17665-1/2, SAL 10^-6). Biocompatibility evaluated per ISO 10993-1/5 (cytotoxicity testing). Digital workflow validated using 3Shape scanner, 3Shape Abutment Designer (K151455), and CORiTEC milling unit. MR Conditional status leveraged from K222044.
Technological Characteristics
Materials: Ti-6Al-4V alloy (ASTM F136) for abutment/screw; 3M Lava Zirconia for superstructure. Two-piece design; gold-colored anodized surface. Connectivity: Digital library files (DME) for CAD/CAM integration. Sterilization: Non-sterile, requires clinic-based sterilization.

#### VII. Product Description:
The Elos Accurate® Hybrid Base™ is intended for attaching to dental implants in order to provide basis for single or multiple tooth prosthetic restorations. The Hybrid Base™ is used as an interface between a dental implant and a zirconia superstructure and will be attached to the implant using the included prosthetic screw and attached to the zirconia superstructure by cementing. The Elos Accurate® Hybrid Base™ is a two-piece abutment composed of the Hybrid Base as the bottomhalf and the zirconia superstructure as the top-half, which when assembled comprises the final finished medical device.
The Elos Accurate® Hybrid Base™ consists of a pre-manufactured prosthetic component in Titanium alloy per ASTM F136, as well as supporting digital library file for 510(k) cleared design software (3Shape Abutment Designer™ Software, K151455) which facilitates the design of a patient specific zirconia superstructure by the laboratory/clinician. The Elos Accurate® Hybrid Base™ fits directly to an endosseous dental implant. The laboratory designed superstructure is manufactured from 510(k) cleared Zirconia (Lava Plus, K011394) according to digital dentistry workflow. For all Elos Accurate® Hybrid Base™ models the zirconia superstructure must be designed according to following limits:
- 1) Minimum wall thickness 0.5 mm
- 2) Minimum post height 4.0 mm (for single unit restorations)
- 3) Maximum gingival height 5.0 mm (min. GH of 0.5mm)
- 4) Maximum angulation 20°
The laboratory designed superstructure is attached to the Elos Accurate® Hybrid Base by use of 510(k) cleared cement (Multilink Hybrid Abutment, K130436 or Panavia V5, K150704) and the final prosthetic restoration is attached to the implant using a Prosthetic screw.
The Elos Accurate® Hybrid Bas has a gold-colored anodized surface to increase the esthetics of the dental restoration - the same surface as in predicate device K201860.
Some of the prosthetic screws are uncoated and two screws are Medicarb coated, identical to the Medicarb coating in predicate device K201860. The subject uncoated screws are compatible with implant platforms Zimmer Screw-vent, Biomet 3i, Neodent GM and Straumann Standard RN and WN. The subject Medicarb coated screws are compatible with the implant platforms Hiossen ET Mini and ET Regular. The purpose of the coating is to lower friction in the thread connection and the screw seat connection.
The Elos Accurate® Hybrid Base™ is delivered non-sterile and the final restoration and corresponding screw is intended to be sterilized at the dental clinic before it is placed in the patient.

#### IX. Summary of the Technological Characteristics:
The subject devices provide additional restorative options for connection to existing implant platforms. The subject devices have similar Indications for Use, intended use, designs, sizes and configurations, materials, and principles of operation as the predicate devices. In order to determine nominal dimensions and tolerances of the Elos Accurate® Hybrid Base™ products, measuring- and dimensional analyses of original manufacturers' components (abutments, implants & abutment screws) have been made.
Comparing to the primary predicate device, the specific language (wording) of the Indications for Use Statements is equivalent except for implant system compatibility and the approach for finalizing the zirconia superstructures. The implant system compatibility of the subject device is extended to include compatibility to the Hiossen, Neodent, Zimmer, Biomet and Straumann implant system platforms. The difference in implant system compatibility is substantiated by engineering and dimensional analysis of original manufactures' components (abutments, implants & abutment screws) for determination of compatibility and new fatigue testing.
The approach of designing and manufacturing the zirconia superstructure for the subject device is either according to a digital dentistry workflow (identical to Primary Predicate Device K201860) or to be sent and manufactured at an FDA registered Elos Medtech approved milling facility (identical
{6}------------------------------------------------
to Reference Device K191919). The subject device does not represent any new worst case, and is thereby covered by existing workflow validation submitted in K201860, except the additional new digital libraries were validated as part of the subject submission, which included following:
- Scanner: 3Shape scanner (accuracy >10μm)
- Design library file (DME-file) provided by Elos Medtech which includes design limits in accordance with "Instruction For Use"
- Design Software: 3Shape Abutment Designer Software (K151455)
- Zirconia Material: 3M Lava Plus Zirconia (K011394)
- Milling Unit: CORiTEC, imes-icore milling unit

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.

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.
