These archforms are designed for treatment of patients with smaller tooth anatomy and/or spacing.
After measuring all anterior teeth for over five years, Dr. Robert L. Waugh has crystalized a method to consistently deliver a predictable anterior display while idealizing functional coupling of anterior teeth.
The Platinum Proportion® Archwire System takes the guess work out of archwire selection based on a simple system of measuring tooth width of the anteriors cuspid to cuspid.
This technique definitively provides the clinician the proper archwire based on the consolidated width.

Determining the Proper Archwire Size
Measure the mesiodistal width of each upper tooth from cuspid to cuspid
The total measurement of all 6 teeth is then used to prescribe archform size: 100%, 92%, or 84%
This case displays a consolidated width of 44.8 mm, indicating consideration of archforms 92% upper & 84% lower.
Selecting Archwires Based on Tooth Widths Total
40mm or Less = Customize 84%
40mm - 45mm = 92% Upper & 84% Lower
45mm - 50mm = 100% Upper & 92% Lower
50mm or More = Customize 100%
