Indications for Use
The BELMAX CM Model X168 X-Ray System is an extraoral source dental panoramic and cephalometric X-ray System intended to produce X-rays for dental radiographic examination and diagnosis of disease of the teeth, jaw, and oral structures.
Device Story
The BELMAX CM Model X168 is a digital dental X-ray system for panoramic and cephalometric imaging. It utilizes an X-ray tube (max 90 kV) and a CCD digital sensor array housed in a removable cartridge to capture radiographic data. The system replaces traditional film/screen cassettes with digital acquisition. Operated by dental professionals in clinical settings, the device produces digital images that are viewed on a computer monitor. Software allows for adjustment of contrast, brightness, and magnification to assist in the identification of skeletal and soft tissue landmarks. By providing enhanced image quality and digital manipulation tools, the device aids clinicians in the diagnosis of dental and jaw pathologies, potentially improving diagnostic accuracy compared to conventional film-based radiography.
Clinical Evidence
Clinical study conducted by Asahi University School of Dentistry with 30 patients. Five orthodontic specialists compared digital images (viewed on monitor with software adjustments) against conventional film images (viewed on view box). Results: Skeletal hard tissue structures observed in 97% of digital images vs 81% of film; soft tissue structures observed in 87% of digital images vs 43% of film; landmark identification clarity was 93.6% for digital vs 81.6% for film. Digital images were rated superior to film for overall quality and landmark identification.
Technological Characteristics
Extraoral dental X-ray system; max peak tube potential 90 kV; CCD digital acquisition sensor in removable cartridge; digital processing; standalone system; compliant with Federal X-ray performance standards.
Indications for Use
Indicated for dental radiographic imaging of the dento-maxillofacial region for the examination and diagnosis of diseases of the teeth, jaw, and oral structures in patients requiring dental X-ray assessment.
Regulatory Classification

### Clinical Tests Discussion
# 807.92(b)(2)
A clinical trial was sponsored and conducted by the Department of Oral Radiology, Asahi University School of Dentistry and included 30 patients receiving a dental examination. Readings were performed by five specialists in orthodontic dentistry. Digital images were observed on a computer monitor using the contrast, brightness, and magnification adjustment function of the ANA-BEL CM software, while X-ray films were observed on a conventional view box.
On BELMAX CM digital images, skeletal hard tissue structures were clearly observed in 97% of the subjects, whereas this fell to 81% for film images. For the depiction of soft tissue structures, 87% of BELMAX CM digital images were rated as sufficient whereas only 43% for film images. The BELMAX CM digital images were rated better than the film images on overall image quality. For landmark identification, the average percentage of sufficient clarity on BELMAX CM digital images was 93.6% and on X-ray film images it was 81.6%.
The BELMAX CM digital images were rated better than the film images for landmark identification.
#### Statement of Compliance with Federal X-ray Performance Standards
The BELMAX CM Model X168 X-Ray System is in compliance with the Federal X-ray performance standards.
#### Conclusion
#### 807.92(b)(3)
The modified device has the same intended use and principle of operation as the prior Takara Belmont devices, as well as substantially equivalent technical specifications. The modifications were implemented to improve the ease of use. maintenance, and image quality, and do not change the intended use or fundamental scientific technology of the device. A hazard analysis, validation testing and clinical study against the generic X-ray film/screen predicate similar to those submitted for the prior Takara Belmont devices were presented to support the substantial equivalence of the modified Takara Belmont system.
The conclusions drawn from the nonclinical and clinical tests demonstrate that the BELMAX CM Model X168 X-Ray System is as safe, as effective and performs as well as or better than the Takara ANA-BEL and ANA-BEL CM Panoramic X-ray system with Takara ADR Plus SSXI Imaging Device and than the Generic X-Ray film.
{3}------------------------------------------------
The BELMAX CM, Takara ANA-BEL and ANA-BEL CM Panoramic X-ray system with Takara ADR Plus SSXI Imaging Device and with the Generic X-Ray film are substantially equivalent.

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.
