Abstract
The present disclosure provides intraoral devices for repositioning the relationship between upper and lower dental arches, particular those in a Class III relation. The devices are attached to appliances on molar teeth of each arch and can be reactivated without removal or replacement of substantial components of the device.
Claims10
An intraoral force module configured for moving the relative positions of upper and lower dental arches, the force module comprising:
- a first member having a first outer end portion, the first member having a length extending in a generally mesial direction when installed on the upper arch;
- a second member pivotally connected to the first member and coupled to a helical compression spring coaxial with at least a portion of said second member, the second member pivotally movable relative to the first member in directions along a first reference axis, a portion of the second member extending distally to a second outer end portion along a portion of the length of the first member, wherein the second member is rotatable relative to a second axis generally parallel to the reference axis when the second member is coupled to an appliance on the arch.

An orthodontic assembly configured for moving the relative positions of upper and lower dental arches, the assembly comprising:
- an upper molar appliance having a passage;
- a first member having a first outer end portion received in the passage, the first member having a length extending in a generally mesial direction;
- a stop coupled to the first member and disposed distal to the passage;
- a second member pivotally connected to the first member and coupled to a helical compression spring coaxial with at least a portion of said second member, the second member pivotally movable relative to the first member in directions along a first reference axis, a portion of the second member extending distally to a second outer end portion along a portion of the length of the first member, wherein the second member is rotatable relative to a second axis generally parallel to the reference axis;
- and
- a lower molar appliance, wherein the second member is rotatably coupled to the lower molar appliance for rotation about the second axis.
