Computed exact-code research

This decision beside its recorded product-code cohort

The 2021–2025 complete-year cohort contains 10 selected decisions under primary code OAT. 10 have valid reported receipt/decision pairs; 0 pairs are missing or invalid.

No quartiles are displayed: this complete-year cohort has fewer than 20 valid pairs.

The table shows the named decision and up to four latest exact-code research records through 2026-09-27. It can include partial-year records outside the complete-year cohort. The quartiles above use the full stated cohort, not this displayed selection.

Use this comparison: select a record to investigate, read its actual indications and design, and document differences. A shared code or elapsed period cannot establish its relevance to your device.

Calendar elapsed days are not active FDA review time, a promised schedule or a success probability. The selection includes only the stated recorded decisions, not all applications. Latest records can postdate the named historical decision and are contextual research, not its predicates. Shared codes, summaries and observed records do not prove equivalence, current market availability, buyer applicability or predicate suitability.

Calculation, selection and source versions

Reuse the complete-endpoint exact-primary-code, documented SE-decision cohort and its stated cutoff/window. Retain its type-7 quartiles only when at least 20 valid date pairs are present. Independently subtract the named official record’s receipt date from its decision date; missing or negative pairs remain unknown. Show up to four latest exact-code research records, excluding the named ID. Parent analysis hash, source snapshots and calculation versions are retained.

Calculation: fda-named-decision-cohort-context-1; cutoff 2026-09-27; 0 parent records excluded; units record counts; calendar elapsed days.

Mico One Orthodontic Screw is indicated for use as a
                                            fixed  anchorage  point  for  attachment  of  orthodontic
                                            appliances  to  facilitate  the  orthodontic  movement  of
                                            teeth.   It is used temporarily   and   is removed   after
                                            orthodontic   treatment   has   been completed.

The excerpt is shortened at a complete statement. Read the complete section in the original PDF before interpreting the evidence.

Compare with your product: Compare the recorded indication, population, body site and use environment with your proposed label. Record each change instead of assuming the primary code settles intended use.

Design and operating principle

K202163 · PDF page 5 ↗ Source 2

The screws are manufactured from commercially
                                            SUS316L (stainless steel) and Ti6AL-4V
                                            (Titanium  alloy).  The  screws  are  available  with
                                            thread diameter are 1.5mm and 2.0 mm, and total
                                            thread lengths is 7.0mm.

The excerpt is shortened at a complete statement. Read the complete section in the original PDF before interpreting the evidence.

Compare with your product: Compare physical design, materials, energy, accessories and operating principle with your design. Ask which documented differences change the evidence scope.

Performance evidence actually described

K202163 · PDF page 8 ↗ Source 3

Read this statement in the original PDF; no complete statement fits the short excerpt.

Compare with your product: The source labels this section as performance data. Determine which described evidence is bench, software, biological or clinical from the actual narrative and original tables; the section label alone does not settle that distinction or prescribe your testing.

Extraction selection and limits

Select observed whole-line section headings or explicit colon-delimited inline labels on readable PDF pages, including the explicitly documented heading-spacing variants in this parser version. Preserve the original heading, character ranges and layout; do not repair excerpt text. Exclude letter boilerplate and uncertain pages. Stop at observed table headings; do not infer table columns or scalar results from layout text. Multi-column or suspicious split-numeric excerpts are excluded until reviewed alternate extraction is available. Original layout records remain retained; any alternate text has its own extractor-version locator and requires original-page review. For each dimension, prefer usable versioned alternate text where available, selecting its longest usable excerpt; otherwise select the longest usable original-layout excerpt. Ties preserve source order. Bounded to 64 PDF pages and 3,500 characters per section. This is a selection, not a complete dossier analysis.

Excluded extraction items: {}.

Historical references beside dated FDA recognition metadata

Read each mention in the linked original summary, including statements that testing was not performed. Recognition metadata does not determine your testing needs, chosen edition or transition eligibility.

Prepare for your provider: the proposed protocol/report edition, its justification for your device and the complete current FDA recognition sheet. In particular, inspect exclusions for partial recognition. An edition difference does not automatically make the historical evidence unusable.

Identifier-matching method and selection limits

Match explicit ISO/IEC identifiers in selected preserved summary excerpts to the acquired, count-reconciled FDA metadata export. Preserve the historical edition mention, current snapshot designations, entry dates, recognition extent and any recorded transition-expiration date as separate facts. No title-similarity, edition-equivalence, test-mandate or transition-eligibility inference. At most twenty matched occurrences and thirty metadata rows per reference; wide matches are held for separate review.

4 of 4 matched reference occurrences shown.

Prepare a differences and evidence worksheet

Use this checklist to gather your business or product details before speaking with a specialist. The items below explain what to record and suggest useful supporting documents. You can add your own answers in the editable project brief.

  1. Indications and users — what differs in our product?

    Compare the recorded indication, population, body site and use environment with your proposed label. Record each change instead of assuming the primary code settles intended use.

    Useful evidence: Our proposed indication, user/population and use environment beside this exact recorded indication.

  2. Design and operating principle — what differs in our product?

    Compare physical design, materials, energy, accessories and operating principle with your design. Ask which documented differences change the evidence scope.

    Useful evidence: Design description, materials/components, accessory list and a differences matrix.

  3. Performance evidence actually described — what differs in our product?

    The source labels this section as performance data. Determine which described evidence is bench, software, biological or clinical from the actual narrative and original tables; the section label alone does not settle that distinction or prescribe your testing.

    Useful evidence: The cited narrative and full tables, underlying protocols/results and a reviewed comparison with the proposed product.

  4. Which edition and recognition limits would our provider rely on?

    Compare each historical reference below with the dated FDA metadata. Ask the specialist to justify the applicable scope and selected edition, read the complete supplementary sheet for partial-recognition exclusions, and investigate any recorded transition conditions. A difference in editions does not automatically make the earlier study unusable.

    Useful evidence: Proposed protocol/report edition, dated FDA recognition sheet with scope/exclusions, and a documented edition/transition rationale for the actual device.
