Platinum Proportion Finished Smiles
Dr. Robert Waugh designed these archforms for treatment of patients with smaller tooth size and/or spacing. After measuring all anterior teeth in his practice for over five years, he has crystalized a method to consistently deliver a predictable anterior tooth display while idealizing functional coupling of anterior teeth. This method can be applied to each and every patient to create the perfect smile arc by placing the cuspid on the “sweet spot”. The Platinum ProportionSM Archwire System takes the guess work out of archwire selection based on a simple system of measuring tooth width of the anterior teeth, 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
40mm or Less = Customize 84%
40mm - 45mm = 92% Upper & 84% Lower
45mm - 50mm = 100% Upper & 92% Lower
50mm or More = Customize 100%
