Abstract
An orthodontic correction system is disclosed for correcting Class II malocclusions, Class III malocclusions, dental asymmetries and/or dental related skeletal anomalies wherein the patient's dentition is permanent or near permanent. The correction system attaches to a patient's dentition via a novel orthodontic appliance that is affixed to, e.g., pre-installed upper and lower archwires. The correction system includes one or more adjustable length assemblies each of whose ends pivotally attach to a patient's preinstalled maxillary and mandibular archwires.
Claims20
An orthodontic system for correcting a malocclusion or an asymmetry, comprising:
- a variable length alignment assembly having a piston assembly including a sleeve and a shaft that mate together in a manner that allows a length of the alignment assembly to be adjusted by a clinician, wherein the piston assembly includes threaded mating portions for varying a length of the alignment assembly;
- a hinge ball at two ends of the alignment assembly, wherein the hinge includes an archwire attachment and a pivot shaft for allowing the archwire attachment to pivot, said ball hinge comprising a spherical head that pivotally attaches to said alignment assembly;
- a first eyelet attached to an end of the sleeve and a second eyelet attached to an end of the shaft;
- and
- wherein the archwire attachment includes an archwire slot for providing an archwire therein and a securing mechanism for fixedly securing the archwire attachment at a desired position along a length of the archwire.
