| Device Class: | Class II |
| Regulation: | 872.5570 |
| Classification Panel: | Dental |
| Product Code: | LQZ, LRK |
| Predicate Device: | ATG/SM-OSA Appliances (K130130). |
Device Description: The SML-OSA2 APPLIANCES include five device models: Adjustable Sleep Appliance (ASA), Clear Sleep Adjustable Dorsal, Clear Sleep Adjustable Anterior, Quiet Night Appliance (QNA) and V-force.
The SML-OSA2 Appliances are customized, intraoral dental devices designed to reduce snoring and mild to moderate obstructive sleep apnea in adults. The devices fit over the dentition and reposition the mandible in a slightly protrusive position. The SML-OSA2 APPLIANCES consist of 2 arch forms that are linked to advance the mandible, and are worn while sleeping to support the lower jaw in a forward position prescribed by the dentist. The customized appliance is inserted and removed by the patient and adjusted by the prescribing dentist.
The SML-OSA2 APPLIANCES are made by Appliance Therapy Group/Space Maintainer Laboratory, which is owned/operated by Selane Products, Inc. Appliance Therapy Group/Space Maintainer Laboratory will manufacture these customized, prescription devices. These reusable (repeated use by one patient) devices will be provided to the patient non-sterile.

appliance is inserted and removed by the patient and adjusted by the prescribing dentist.
## TECHNOLOGICAL CHARACTERISTICS:
## Intended Use
The Indications for Use for the SML-OSA2A Appliances are identical to the ATG/SM-OSA Appliances' Indications for Use. Both the proposed and predicate devices are intended to reduce nighttime snoring and mild to moderate obstructive sleep apnea in adults A more in-depth comparison of the materials of construction is provided in the Substantial Equivalence section.
## Design
The SML-OSA2 APPLIANCES are made primarily of dental acrylic. Three modified designs (ASA, Clear Sleep Adjustable Dorsal, and Clear Sleep Adjustable Anterior) are a variation of the Dorsal design. Two modified designs (QNA and V-force) are a variation of the Herbst design. Stainless steel or elastomeric parts are incorporated to allow adjustment of the appliances. These designs may have dual-laminate dental polymers in place of the acrylic. Table S-1 summarizes the design characteristics of the five models of the proposed device.
The function, scientific concept and principle of operation are the same for each device design. The principle of operation is that two connected arch forms maneuver the mandible forward. The position of the mandible prevents the tongue from sliding backward or downward for a prone sleeping individual. Therefore, the airway will be more open, contributing to the reduction in snoring and mild to moderate sleep apnea.

{7}------------------------------------------------
The indications for use are identical for the predicate K130130 and subject K162816 devices. No significant differences exist in technology, intended use, or design between the subject devices and the predicates selected.
## Performance Standards:
- ISO 7405 Second edition 2008-12-15, dentistry evaluation of biocompatibility of medical . devices used in dentistry as published in the Federal Register (Food and Drug Administration Modernization Act of 1997: Modifications to the List of Recognized Standards, Recognition List Number: 036; 07/09/2014).
- The special control for these devices is the FDA guidance document entitled "Class II . Special Controls Guidance Document: Intraoral Devices for Snoring and/or Obstructive Sleep Apnea: Guidance for Industry and FDA." [Nov. 12, 2002]
## Biocompatibility:
The predicate and subject devices are considered to be external communicating devices of permanent exposure (>30 days) per ISO 7405 and surface-contacting devices (mucosa) of permanent contact (>30 days) per ISO 10993-1. No changes have been made in the primary materials of construction from the sponsor's own predicate device. In some models, stainless steel connecting parts have been substituted with Polyoxymethylene (POM) or intraoral latex rubber elastomers.
No biocompatibility tests have been performed for the modified devices; the new materials have als o been used in other cleared intraoral devices and implantable devices.
## Clinical Testing:
No clinical testing is required for these devices.
### Risk Analysis:
A risk analysis including an evaluation of the materials of construction and design was performed. The function of mandibular advancement devices requires that the prescribing dentist be cognizant of the potential for TMJ soreness, soft tissue soreness, and dentition complications (soreness, motion, loosening) by mandibular advancement. The contraindications, warnings, precautions, storage directions, prescription preparation instructions, fitting and adjustment directions are provided to avoid potential problems from arising or persisting with the dentition, tissue, or joints. A risk related to the polymer spacers was addressed. No significant new risks were identified.
### Conclusions:
The subject devices have identical indications for use to the predicate devices. The intended use, materials of construction, technology, principle of operation, and designs of the SML-OSA2 Appliances are comparable to the legally marketed predicate. Therefore, the proposed SML-OSA2 Appliances are substantially equivalent to the predicate.

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.
