Fiber Disks and Blocks (TRINIA) are milling blanks composed of a multi-directional interlacing of fiberglass and resin in several layers. They are intended to be used solely by dental technicians and dentists for making copings, substructures, or frameworks for permanent and transitional anterior or posterior crowns, bridgework, and substructures that can be for either cemented or uncemented restorations (e.g. telescopic restorations).
Device Story
TRINIA is a fiber-reinforced resin milling blank consisting of multi-directional glass fiber layers embedded in modified epoxy resin. Used by dental technicians and dentists in dental labs or clinics to manufacture non-metallic dental appliances, including copings, substructures, and frameworks for crowns and bridges. The device is processed via CAD/CAM milling or manual copying techniques. No post-fabrication curing is required, as the material possesses necessary mechanical properties upon milling. The device is designed to withstand oral chewing forces through high flexural and compressive strength and is insoluble in water to prevent degradation in the oral cavity. By eliminating curing steps, the device reduces potential for fabrication errors and extends working time for the technician. The final appliance is used by the clinician to restore patient dentition, providing a durable, biocompatible framework for permanent or transitional restorations.
Clinical Evidence
No clinical data. Substantial equivalence is supported by bench testing including flexural strength (393 MPa), flexural modulus (18.8 GPa), tensile strength (169 MPa), compression strength (347 MPa), Charpy impact (26 KJ/m²), and water absorption (0.03%). Biocompatibility testing confirmed the device is non-mutagenic (ISO 10993-3), non-cytotoxic (ISO 10993-5), non-irritant (ISO 10993-10), and non-toxic (ISO 10993-11).
Technological Characteristics

RESEARCH METHODOLOGY
{2}------------------------------------------------
#### Identification of the risk analysis method
Bicon has conducted a preliminary hazard analysis which identified risks, including risk of mechanical failure. toxicity and adverse tissue reaction, improper use, and incompaibility with other dental devices. The Failure Modes Effect Analysis (FMEA) showed that all risks, when reduced as far as possible, were acceptable. There were no risks that were so severe as to cause severe damage or lead to the death of a patient. The mechanical properties of the device are comparable to predicate The biocompatibility testing of the composite resin device showed that TRINIA is devices. biocompatible. The labeling of the device was designed to alert the user of any residual risks or warnings.
#### Discussion of the device characteristics
To reduce the risk of mechanical failure, TRINIA was designed to have a high compressive and flexural strength to withstand the chewing forces. In order to achieve this, the materials and the weave of the fabric were essential to the design; a weave that was too tight could result in the device not able to be cut with standard milling tools, while a weave that was too loose might result in a weaker compressive and flexural strength. In addition, the device was designed to be insoluble to water which is of importance in the oral cavity. This characteristic prevents breakdown of the device as well as preventing the device from entering the patient's body in a manner not intended by the manufacturer. A third characteristic that reduces the risk of mechanical failure of TRINIA is that the operator of the device does not need to perform any additional steps to make TRINIA function at the mechanical specifications. There are no curing steps needed; only milling of the dental appliance is required. This prevents improper fabrication due to varying curing or working times. The possibility of varying depth of cure is also avoided.
To reduce the risk of toxicity and adverse tissue reaction, TRINIA was tested against biocompatibility standards as specified by ISO 7405:2008, Dentistry - Evaluation of biocompatibility of medical devices used in dentistry. TRINIA is made out of materials that are not deadly in the health hazard rating and cause no cytotoxic effects.
To reduce the risk of improper use, TRINIA was designed to have the fewest steps possible for the user. As stated earlier to reduce the risk of mechanical failure, there are no curing steps required. This reduces the possibility of the user performing the curing incorrectly, as there are no curing steps. The working time for TRINIA is therefore extended and the user does not need to rush to finish the dental appliance.
#### Description of the performance aspects (21 CFR 807.92 (b)(1)(2))
The testing of the performance aspects was performed to recognized standards, such as ASTM or ISO. The following table lists the test and the test method used to obtain the actual result shown.

* NS = Not Specified
Clinical testing is not required to demonstrate substantial equivalence as the indications for use is similar to legally marketed devices, the design is similar to designs previously cleared under a premarket notification, and the technology used in TRINIA is not a new technology.
#### Reliance on standards
Testing has been performed to the standards listed in the "Description of the performance aspects" section. A FDA Form 3654 has been completed for each of the standards listed in this 510(k). There were no deviations to the procedure of the standard for the tests performed.
#### Conclusion
TRINIA is substantially equivalent in safety and effectiveness to the predicate device based on the results of the physical property and biocompatibility testing. There are no substantive differences in the indications for use or technology, including features, materials, and principals of operations, from the predicate device.

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.
