Orthodontic appliance for bite correction
View Patent ↗A bite-correcting orthodontic appliance attaches directly to the elements of braces (i.e., brackets and archwires); flexes in its distal 25-45% to stay away from the food bolus; has a smooth rectangular profile for patient comfort; and introduces gentle force vectors to the patient's upper and lower teeth that sweep in an arch to lift up on the front of the molar and down on the lower front teeth as the appliance tries to return to its preinstalled (passive) state, resulting in rapid, yet gentle changes unseen in the orthodontic industry. A lock-and-key attachment member is disclosed allowing for ease of installment in the patient's mouth.
1. A orthodontic appliance for treating malocclusions, with a flexible end and a rigid end, wherein a flex point occurs at the mid-point of said flexible end, comprising:
a rigid member;
a sliding member for sliding engagement within said rigid member;
a flexible coil spring containing said flex point;
an unwound extension of said coil spring for bendable attachment with a molar tube;
a connection key; and
a keyway;
wherein a first end of the rigid member is secured to a said flexible coil spring and a second end of the rigid member is secured to said connection key via said sliding member;
wherein said connection key is designed for mating and locking engagement with said keyway;
wherein said keyway is designed for attachment to an archwire; and
wherein said flex point occurs within 25-45% of a total appliance length from said unwound extension;
whereby said orthodontic appliance when installed in a patient's mouth exerts a gentle sweeping force, pushing on the patient's upper and lower jaws in an intrusive fashion.
2. The orthodontic appliance of claim 1 wherein said rigid member is rectangular in cross-section.
3. The orthodontic appliance of claim 1 wherein said flexible coil elliptical in cross-section.
4. The orthodontic appliance of claim 1 wherein said flexible coil is circular in cross-section.
5. The orthodontic appliance of claim 1 wherein said sliding member is rectangular in cross-section.
6. The orthodontic appliance of claim 1 wherein said connection key comprises a t-shaped member extending normally therefrom for locking engagement with said keyway.
7. A orthodontic appliance for installation within a patient's mouth residing between the cheek and the gum line, for treating malocclusions, with a flexible end and a rigid end, wherein a flex point occurs at the mid-point of said flexible end, comprising:
a rigid member;
a sliding member for sliding engagement within said rigid member;
a flexible coil spring containing said flex point;
an unwound extension of said coil spring for bendable attachment with a molar tube;
a connection member;
a connection key; and
a keyway;
wherein said rigid member is secured to said flexible coil spring via the connection member at a first end, and is slidably engaged with said sliding member at a second end;
wherein said connection member is located on a cheek-side of said rigid member and is matingly configured to accept the end of said flexible coil spring;
wherein said connection key is designed for mating and locking engagement with said keyway;
wherein said keyway is designed for attachment to an archwire; and
wherein said flex point occurs within 25-45% of a total appliance length from said unwound extension;
whereby said orthodontic appliance when installed in a patient's mouth exerts a gentle sweeping force, pushing on the patient's upper and lower jaws in an intrusive fashion.
8. The orthodontic appliance of claim 7 wherein said rigid member is rectangular in cross-section.
9. The orthodontic appliance of claim 7 wherein said flexible coil elliptical in cross-section.
10. The orthodontic appliance of claim 7 wherein said flexible coil is circular in cross-section.
11. The orthodontic appliance of claim 7 wherein said sliding member is rectangular in cross-section.
12. A orthodontic appliance for treating malocclusions, with a flexible end and a rigid end, wherein a flex point occurs at the mid-point of said flexible end, comprising:
a rigid member;
a non-rotatable sliding member for sliding engagement within said rigid member;
a flexible coil spring containing said flex point;
an unwound extension of said coil spring for bendable attachment with a molar tube;
a connection member;
a connection key; and
a keyway;
wherein said rigid member is secured to said flexible coil spring via the connection member at a first end, and is slidably engaged with said sliding member at a second end;
wherein said connection member is located on a cheek-side of said rigid member and is matingly configured to accept the end of said flexible coil spring;
wherein said connection key is designed for mating and locking engagement with said keyway;
wherein said keyway is designed for attachment to an archwire; and
wherein said flex point occurs within 25-45% of a total appliance length from said unwound extension;
whereby said orthodontic appliance when installed in a patient's mouth exerts a gentle sweeping force, pushing on the patient's upper and lower jaws in an intrusive fashion.
