| 摘要 | Proportional dividers, set at a ratio of about 6.0:7.2, are used to transfer tooth width measurements from a patient''s model to an archwire in a manner increasing measurements to allow for factors such as the greater circumferential length of the archwire relative to the combined widths of associated teeth. | ||||||
| 权利要求 | 1. The method of marking tooth width measurements, taken from a patient''s model, on an archwire, comprising: a. providing proportional dividers and setting said dividers on a ratio of about 6.0:7.2, b. providing an archwire card and transferring tooth width measurements from said patient''s model to said card by using said dividers in a manner increasing card measurements by said ratio, and c. transferring card measurements from said archwire card to said archwire and marking the measurements on said archwire. 2.
