Abstract

An improved orthodontic assembly and method is disclosed. The orthodontic assembly includes opposing complementary bite blocks separately mountable utilizing separate mounting assemblies. Preferably, the mounting assembly for at least one of the upper or lower bite blocks of each upper/lower set allows for selective antero-posterior positioning. Each bite block preferably comprises a preformed portion and a formable layer that can be adapted to an occlusal surface for flush mounting thereupon.

Claims

1. An orthodontic assembly comprising:

a first lower bite block having an angled cam surface;

a first upper bite block having an angled cam surface complimentary to the cam surface of said first lower bite block; and

a mounting assembly for separately mounting at least one of said first lower bite block and first upper bite block, including;

attachment means adapted to be fixedly attached directly to a tooth;

block connection means connected to said at least one of said blocks; and

,

interconnection means for selectively interconnecting said attachment means and said block connection means.

2. An orthodontic assembly as recited in claim 1, said interconnection means comprising:

a first male member interconnected to one of said attachment means and block connection means; and

,

a first female member interconnected to the other of said attachment means and block connection means for receiving said first male member.

3. An orthodontic assembly as recited in claim 2, wherein one of said first male member and first female member slidably engages said one of said attachment means and block connection means.

4. An orthodontic assembly as recited in claim 3, wherein the other of said first male member and said first female member is fixedly connected to the other of said attachment means and block connection means.

5. An orthodontic assembly as recited in claim 3, wherein said one of said first male member and first female member is axially and rotatably positionable relative to said one of said attachment means and block connection means.

6. An orthodontic assembly as recited in claim 1, said block connection means including:

a first extending portion connected to a first side of said at least one of said blocks, said first extending portion being positionable adjacent to a lingual surface of said tooth; and

a second extending portion connected to a second side of said at least one of said blocks, said second extending portion being positionable adjacent to a buccal surface of said tooth.

7. An orthodontic assembly as recited in claim 6, said interconnection means comprising:

first connection means for selective interconnection of said first extending portion of said block connection means and a lingually disposed portion of said attachment means;

second connection means for selective interconnection of said second extending portion of said block connection means and a buccally disposed portion of said attachment means.

8. An orthodontic assembly as recited in claim 7, wherein said first connection means and first extending portion are disposed for horizontal mating and relative slidable engagement.

9. An orthodontic assembly as recited in claim 7, wherein said first connection means comprises:

at least one vertically oriented female member fixedly connected to said lingually disposed portion of said attachment means; and

a dual connection member having at least one vertically oriented male member selectively positionable within said one female member, and an interconnected, horizontally oriented portion for selective horizontal mating and relative slidable engagement with said first extending portion of said block connection means.

10. An orthodontic assembly as recited in claim 9, wherein said second connection means comprises:

a horizontally oriented member fixedly interconnected with said buccal portion of said attachment means for selective horizontal mating and relative slidable engagement with said second end portion of said block connection means.

11. An orthodontic assembly as recited in claim 10 wherein said horizontally oriented portion includes a first horizontal tube.

12. An orthodontic assembly as recited in claim 11, wherein:

said horizontally oriented portion further comprises a second horizontal tube.

13. An orthodontic assembly as recited in claim 6, wherein said at least one bite block is selectively positionable at a plurality of locations relative to said tooth.

14. An orthodontic assembly as recited in claim 6, said first and second extending portions being integrally interconnected by an intermediate portion therebetween, said intermediate portion being positioned within said at least one of said blocks.

15. An orthodontic assembly as recited in claim 1, said at least one of said blocks comprising:

a preformed portion having a tooth facing surface; and

a formable layer selectively adjoined to said tooth facing surface and being formable to flushly engage an occlusal surface of said tooth.

16. An orthodontic assembly as recited in claim 1, further comprising:

at least one spacer selectively adjoinable to the cam surface of at least one of said first lower bite block and first upper bite block.

17. A method for providing an orthodontic assembly for use on one or more of a patient'"'"'s teeth, comprising the steps of:

supplying at least a first preformed lower bite block and at least a first preformed upper bite block, said blocks having complementary angled cam surfaces, and each of said blocks having a tooth facing surface;

providing a layer of a formable material to the tooth facing surface of at least one of said first lower bite block and first upper bite block;

positioning said at least one of said blocks in a desired location on and relative to an occlusal surface of one of either said patient'"'"'s teeth or a patient'"'"'s study model thereof;

forming an outer surface of said formable material to the shape of said occlusal surface by applying force to said one block;

at least partially hardening said formable material on said occlusal surface;

removing said at least one of said blocks from said occlusal surface; and

interconnecting said at least one of said blocks to said teeth.

18. A method for providing an orthodontic assembly for use, as recited in claim 17, wherein:

said formable material is selected from the group comprising;

thermoplastic elastomer materials, light-curable compositions, chemically-curable compositions, thermoplastics and thermoset plastics.

19. A method for providing an orthodontic assembly for use, as recited in claim 17, wherein:

said at least one of said bite blocks is transparent;

said formable material comprises a light-curable composition; and

said partial hardening step includes;

exposing said at least one of said bite blocks and formable material to visible light.
