Conditioning of silica-based ceramic surfaces for the adhesive bond with luting composites
Device Story
Monobond Etch & Prime is a dental conditioning agent used extra-orally by dental technicians to prepare silica-based ceramic surfaces for bonding with luting composites. It functions as a single-step solution that combines etching and silanization, replacing the traditional separate step of etching with 5% hydrofluoric acid. The device contains silane, a ceramic etching agent, and adhesive monomers. By eliminating the need for separate hydrofluoric acid etching, the device simplifies the preparation process for silica glass ceramics. The healthcare provider applies the agent to the ceramic surface to enable subsequent bonding with luting composites (e.g., Variolink or Multilink lines). The device benefits the patient by ensuring a reliable adhesive bond for ceramic restorations.
Clinical Evidence
Bench testing only. Tensile bond strength testing was performed to compare the subject device to the predicate. Results demonstrated that the performance of Monobond Etch & Prime conforms to specifications and is substantially equivalent to the predicate. Biocompatibility was assessed according to EN ISO 10993-1:2009 and EN ISO 7405:2008.
Technological Characteristics
Liquid solution containing silane, ceramic etching agent, and adhesive monomers. Applied extra-orally. Tested per ISO 1641:2009. Biocompatibility tested per EN ISO 10993-1:2009 and EN ISO 7405:2008. No software or electronic components.
Indications for Use
Indicated for the conditioning of silica-based ceramic surfaces to facilitate adhesive bonding with luting composites. Limited to extra-oral application on silica-based ceramics; not indicated for oxide ceramics, metal, composite, or fiber-reinforced composites.

Device Description: Monobond Etch & Prime is used to condition silica-based ceramic surfaces for the adhesive bond with luting composites from the Variolink or Multilink product lines, for example, Monobond Etch & Prime etches and silanizes silicate ceramic suffaces in one working step. The new product combines the role of bonding agent with that of etchant. Typically the dental technician would etch the ceramic with 5% hydrofluoric acid but this step is achieved using Monobond Etch & Prime. The etching step was carried out outside the mouth and the new product is also limited to extra-oral applications of the new product are limited to silica ceramics, Oxide ceramics, metal, composite and fibre-reinforced composites are not indicated. This is because only silica glass ceramics required etching with hydrofluoric acid and therefore the benefit of using Monobond Etch & Prime is primarily relevant for this group of materials.
### Intended Use:
Conditioning of silica-based ceramic surfaces for the adhesive bond with luting composites

| Predicate - Monobond Plus (K090826) | Subject Device |
|--------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Bonding agent between luting composites and glass/oxide ceramic, metal, composite and fiber-reinforced composite restorations. | Conditioning of silica-based ceramic surfaces for the adhesive bond with luting composites. |
| Monobond Plus is a dilute solution of adhesive monomers and silane which enable it to be used with various substrates. | Monobond Etch & Prime is a dilute solution of silane, a ceramic etching agent and an adhesive monomer, and can be used only with silica ceramics |
| Tensile bond strength to glass ceramics was tested for comparison purposes to the subject device. | Tensile bond strength testing showed that the performance of the subject device is conforming to the specification and substantially equivalent to the predicate device. |
Technological Characteristics and Testing Summary: As no product specific standard exists for the subject device, testing was conducted under ISO 1641:2009 Dentistry - Medical Devices for dentistry - Materials.
The device was tested for Tensile bond strength. The predicate referred to shear bond strength. The methods and specifications cannot be directly compared. However, tests for Monobond Etch & Prime and Monobond Plus tensile bond strength showed that the performance of the new product is conforming to the specification and substantially equivalent to the predicate. Only the bond strength to glass ceramics is considered as use with oxide ceramics is not indicated for Monobond Etch & Prime. The key function of Monobond Etch & Prime is to silanise silica glass ceramics. This is achieved using exactly the same silane agent as used in Monobond Plus. Although the compositions are different, the subject device has been assessed for biocompatibility through testing according EN ISO 10993-1:2009 and EN ISO 7405:2008.
The device design, i.e. delivery form, and the predicate device are the same. They are both applied extra-orally. The Intended use of the subject and the predicate device are the same except that the subject device is limited for use with silica-based ceramic surfaces. This be because only silica glass ceramics require etching with hydrofluoric acid and therefore the benefit of using the subject device is relevant for this group of materials.
CONCLUSION: The above data and analysis demonstrates that Monobond Etch & Prime is substantially equivalent to the predicate device.

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.
