Source-derived summary

An Adams clasp is a component used to retain a custom-made medical device in the mouth. The clasp functions by engaging the mesiobuccal and distobuccal undercuts of a tooth, typically the maxillary first molar and is used to retain a wide range of devices prescribed in a variety of medical and dental specialties.

Synonyms

The Adams clasp is so named because it was invented by English orthodontist C. Philip Adams. It was originally referred to as the modified arrowhead clasp and has been called the Liverpool clasp because it was developed at the Liverpool Dental School where Adams lectured. The terms Adams crib and universal clasp have also been used.

Material

The component is formed from a length of hard stainless steel wire with Adams universal pliers. The wire for a permanent tooth is typically 0.7mm in diameter but 0.8mm can also be used, especially for clasps that are made to fit two teeth. A clasp for a deciduous tooth can be made from 0.6mm or 0.7mm wire and 0.6mm wire has been advocated for a canine.

Editorial summary

Begin with the source’s own compact description: “Adams clasp” is medical intervention. The dossier treats that line as a proposition to test through Adams, clasp and medical, not as a finished interpretation.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 177-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Adams, clasp and medical is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “medical intervention” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 26, 2026. The linked authority identifier is Q96371459. None of the 0 selected statements returned an explicit reference.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
