  • Patent number: 7008221
    Abstract: The present invention is directed to selection of individual patient archwires by examining the patients inner arch rather than the patients teeth. In particular, a method of archwire selection comprises (a) obtaining a representation of a patient's inner arch curve (a “PIAC”); (b) selecting an archwire shape based at least partially on the PIAC representation; (c) making an initial selection of an archwire size based at least partially on the PIAC representation; (d) selecting a final archwire size after considering something other than the PIAC representation; and (e) selecting an archwire to be used based on the selected archwire shape and selected final archwire size. Using the PIAC rather than the occlusal or labial and buccal surfaces of the teeth for archwire shape selection promotes shaping the teeth to the shape of the jaw bone and gives consistent facial esthetics plus better retention of the treatment correction.

  • Patent number: 5115799
    Abstract: A lip and cheek retracting device formed from a rigid sheet of autoclavable material. A first pair of opposing prongs with a first space formed therebetween extends in the opposite direction of a second pair of opposing prongs with a second spaced formed similarly therebetween. The first pair of prongs are shaped to fit around an adult's gum ridge, and the second pair of prongs are shaped to fit around a child's gum ridge. An indented curvature formed in each portion of the peripheral edge lying between one prong of the first pair of opposing prongs and one prong of the second pair of opposing prongs is used for manually holding the device in place during use.
