Description
For nonnegative holeDiameter, screwDiameter, and eccentricity return radialClearance=(hole-screw)/2, minimumGap=radialClearance-eccentricity, and fits when holeDiameter-screwDiameter>=2*eccentricity.
Oral laboratory and research records use specimen labels, model coordinates, material quantities, event times, and device identifiers. A matching label or dimensional clearance answers a narrower question than verified anatomy, traceability, or clinical suitability. Source identity, reference frames, and measurement units must remain explicit.
For nonnegative holeDiameter, screwDiameter, and eccentricity return radialClearance=(hole-screw)/2, minimumGap=radialClearance-eccentricity, and fits when holeDiameter-screwDiameter>=2*eccentricity.
When to use this tool
Use Oral Surgery Phantom Screw Clearance Gap when you need this specimen-record, device-label, timing, material, or model-geometry check.
How to use the tool and how it works
- Enter holeDiameter, screwDiameter, eccentricity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read radialClearance, minimumGap, fits. Inspect fits before interpreting the associated values.

}Limitations and assumptions
- Lengths need one unit and circular sections with parallel axes are assumed. Fits is a phantom geometry budget, not verification of tolerances, mechanical fixation, safe surgical guidance, or patient suitability.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- 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. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use authenticated records and the intended laboratory or measurement protocol for the full task. Verify source labels, coordinate frames, calibration, and the limits of the supplied physical model.
