Description
Evaluate an explicit bench image-signal threshold rule without selecting a clinical contact criterion.
Dental laboratory and prosthetic research records distinguish measured dimensions, reference targets, material quantities, and evidence flags. Ratios and residuals depend on those measurement conventions. An idealized bench term or metadata match is separate from fabrication quality and clinical fit or suitability.
Evaluate an explicit bench image-signal threshold rule without selecting a clinical contact criterion.
When to use this tool
Use Occlusal Film Contact Threshold Token when you need the stated laboratory, bench, geometry, or device-record term from already supplied measurements or annotations.
How to use the tool and how it works
- Enter signal, suppliedThreshold, equalityIsContact, higherIsContact. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read contactUnderRule. Inspect contactUnderRule before interpreting the associated values.
Orient signal-suppliedThreshold using higherIsContact and return contactUnderRule for a positive oriented difference, admitting equality only with equalityIsContact.1

}Limitations and assumptions
- Threshold, direction, and equality rule are supplied. This does not detect real occlusal contact from images, infer force, validate a measurement, or recommend treatment.
- The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Signed zero is exported as zero.
Alternative or Complementary methods
Use calibrated measurements and an appropriate complete geometric, material, or laboratory method when the task requires more than one bench term. Clinical suitability requires a separate professional assessment.
