Abstract

An orthodontic apparatus for treating skeletally based dental malocclusions. The orthodontic apparatus includes cooperating upper and lower surface apparatus for causing a mandibular displacement in a desired direction during an act of biting. An adjustment apparatus sets a relative position of the cooperating upper and lower surfaces.

Claims

1. An orthodontic apparatus for treating skeletally based dental malocclusions, the orthodontic apparatus comprising:

(a) upper palate plate means having an adjustable block mount and a moveable bite block slideably attached to the adjustable block mount;

(b) lower plate means having a lower bite block wherein the lower bite block has a first surface; and

(c) adjustment means, affixed to the upper palate plate, for positioning said moveable bit block, the moveable bite block having a second surface the second surface being positioned and arranged to contact the first surface so as to provide a malocclusion correction force.

2. The orthodontic apparatus of claim 1 further comprising a retainer means partially embedded within the upper palate plate means.

3. The orthodontic apparatus of claim 2 wherein the first surface and second surface cooperate during biting so as to treat Class 2 malocclusions.

4. The orthodontic apparatus of claim 3 wherein the adjustment means further comprises:

(a) a drive tube apparatus embedded within the upper palate plate means; and

(b) a drive shaft means having a threaded end embedded within the drive tube apparatus and an anchored end embedded within the moveable bite block.

5. The orthodontic apparatus of claim 1 wherein the first surface and second surface cooperate during biting so as to treat Class 2 malocclusions.

6. The orthodontic apparatus of claim 1 wherein the adjustment means further comprises:

(a) a drive tube apparatus embedded within the upper palate plate means; and

(b) a drive shaft means having a threaded end within the drive tube and an anchored end within the moveable bite block.

7. The orthodontic apparatus of claim 1 wherein the moveable bite block has an upper pressure surface for providing a contact point for additional support and force for mandibular displacement.

8. The orthodontic apparatus of claim 1 wherein the moveable bite block contacts the mouth to provide support in the vertical plane of the mouth.

9. The orthodontic apparatus of claim 1 wherein the adjustment means further comprises a wire connector having a first end embedded in the moveable bite block and a cylinder embedded in the upper palate plate for slideably receiving a second end of the wire connector.

10. An adjustable orthodontic apparatus for treatment of a malocclusion, comprising:

(a) upper palate plate means conformed to fit within a patient'"'"'s mouth, the upper palate plate means comprising a first bite block conformed to be positioned over an occlusal surface of a maxillary first molar;

(b) a retainer means for securing attachment of the upper palate plate means, the retainer means being affixed to the upper palate plate means;

(c) a moveable bite block comprising a first surface;

(d) a lower plate having a lower bite block comprising a second surface positioned so as to oppose and cooperate with the first surface so as to produce a mandibular displacement;

(e) a connecting and stabilizing means, connected between the first bite block and the moveable bite block, for slideably connecting the moveable bite block to the first bite block and stabilizing a position of the moveable bite block; and

(f) an adjustment means for moving and fixing a position of the moveable bite block relative to the first bite block, the adjustment means having a first adjustment element affixed to the first bite block and a second adjustment element affixed to the moveable bite block.

11. The adjustable orthodontic apparatus of claim 10 wherein the retainer means comprises a plurality of wire retainer means partially embedded within the palate plate means.

12. The adjustable orthodontic apparatus of claim 11 wherein the first surface and the second surface cooperate as to treat Class 2 malocclusions.

13. The adjustable orthodontic apparatus of claim 12 wherein the adjustment means comprises:

(a) a drive tube apparatus embedded within the first bite block; and

(b) a drive shaft means having a threaded end within the drive tube and an anchored end within the moveable bite block.

14. The adjustable orthodontic apparatus of claim 13 wherein the connecting and stabilizing means comprises a wire connector means looped through the moveable bite block the wire connector means having two parallel ends that slideably engage the moveable bite block to the first bite block, thereby allowing the moveable bite block to be extended and retracted,

15. The adjustable orthodontic apparatus of claim 10 wherein the first surface and the second surface cooperate so as to treat Class 2 malocclusions.

17. The adjustable orthodontic apparatus of claim 10 wherein the connecting and stabilizing means comprises a wire connector means looped through the moveable bite block, the wire connector means having two parallel ends that slideably engage the moveable bite block to the first bite block, thereby allowing the moveable bite block to be extended and retracted.

18. The orthodontic apparatus of claim 10 wherein the connecting and stabilizing means further comprises a wire connector having a first end embedded in the moveable bite block and a cylinder embedded in the first bite block plate for slideably receiving a second end of the wire connector.

16. The adjustable orthodontic apparatus of claim 16 wherein the adjustment means comprises:

(a) a drive tube apparatus embedded within the first bite block; and

(b) a drive shaft means having a threaded end within the drive tube and an anchored end within the moveable bite block.
