    • نبذة مختصرة :
      The present invention relates to methods for the restoration of a decayed portion of an anterior tooth or re-restoration of a previously filled anterior tooth, and to dental matrices and composite resin dispensers that may be used in the methods for the restoration of a decayed portion of an anterior tooth
    • Inventors:
      Clark, David J. (Lakewood, WA, US)
    • Claim:
      1. A dental matrix comprising: a non-flat sectional strip having a first end and an opposed second end, wherein the strip includes at least one anatomic feature dimensioned for a surface of an anterior tooth.
    • Claim:
      2. The dental matrix of claim 1 wherein: the strip has a length from the first end to the second end such that the strip can cover at least 90 degrees around side surfaces of the anterior tooth covered by the strip.
    • Claim:
      3. The dental matrix of claim 1 wherein: the matrix is translucent.
    • Claim:
      4. The dental matrix of claim 1 wherein: the strip is pre-curved and universal for any interproximal surface of any anterior tooth.
    • Claim:
      5. The dental matrix of claim 1 wherein: the matrix includes a pronounced root-crown interface.
    • Claim:
      6. The dental matrix of claim 1 wherein: the matrix is side specific for the anterior tooth.
    • Claim:
      7. The dental matrix of claim 1 wherein: the matrix is tooth specific for the anterior tooth.
    • Claim:
      8. The dental matrix of claim 1 wherein: the matrix is tooth and surface specific for the anterior tooth.
    • Claim:
      9. The dental matrix of claim 1 wherein: the matrix is fully anatomic for the anterior tooth.
    • Claim:
      10. The dental matrix of claim 1 wherein: the matrix is anatomically shaped such that the matrix is self stabilizing and hands free for the anterior tooth.
    • Claim:
      11. The dental matrix of claim 1 wherein: the matrix includes a side flange that extends away from the first end.
    • Claim:
      12. The dental matrix of claim 1 wherein: the strip has a length from the first end to the second end such that the strip can cover 360 degrees around the side surfaces of the anterior tooth covered by the strip.
    • Claim:
      13. The dental matrix of claim 1 wherein: the strip has a length from the first end to the second end such that the strip can cover from 90 degrees up to 359 degrees around the side surfaces of the anterior tooth covered by the strip.
    • Claim:
      14. A method for the restoration of an anterior tooth having an original shape including an interproximal surface, the method comprising: (a) removing a portion of the interproximal surface of the tooth to form a hollow cavity preparation; (b) surrounding the removed portion of the interproximal surface of the tooth with the matrix of claim 1; (c) extruding a flowable composite resin into the hollow cavity preparation; (d) extruding a paste composite resin into the pool of the flowable composite resin before light curing the pool of the flowable composite resin; and (e) simultaneously light curing the flowable composite resin and the paste composite resin contained in the cavity preparation.
    • Claim:
      15. The method of claim 14 wherein: step (c) comprises extruding the paste composite resin through a step down tip of the dispenser.
    • Claim:
      16. The method of claim 14 wherein: step (c) comprises extruding the paste composite resin through a step down tip inserted into a capsule containing the paste composite resin, the capsule being loaded in the dispenser.
    • Claim:
      17. The method of claim 14 wherein: the paste composite resin has a volume shrinkage of 3% or less upon curing.
    • Claim:
      18. The method of claim 14 wherein: the paste composite resin has a volume shrinkage of 1% or less upon curing.
    • Claim:
      19. The method of claim 14 wherein: the paste composite includes greater than 30% by volume filler.
    • Claim:
      20. A method for the restoration of an anterior tooth having an original shape including an interproximal surface, the method comprising: (a) removing a portion of the interproximal surface of the tooth to form a hollow cavity preparation; (b) surrounding the removed portion of the interproximal surface of the tooth with the matrix of claim 1; (c) extruding a heated light-curable paste composite resin into hollow cavity preparation; and (d) curing the paste composite resin contained in the cavity preparation.
