Method and apparatus for sealing root canals and anchoring teeth

Claim 1

A method of sealing the root canal of a tooth of a patient comprising the steps of removing portions of the tooth in axial alignment with the root canal of the tooth to be treated; providing a longitudinal, generally cylindrical-shaped recess extending through the tooth; cleansing and preparing the cylindrical recess; inserting a sealing cement therein; inserting and rotating a solid tapered filler having a circular crosssection throughout substantially its entire length, and having helixes extending upward from the tapered end over a given length thereof, until the tapered end of the filler has reached the Apex of the tooth and the helixes have engaged essentially the apical one-third of the root canal.

Claim 2

A method of sealing the root canal of a tooth of a patient comprising the steps of removing portions of the tooth in axial alignment with the root canal of the tooth to be treated; providing a longitudinal, generally cylindrical-shaped recess extending through the tooth; cleansing and preparing the cylindrical recess; inserting a sealing cement therein; inserting and rotating a solid tapered filler having a circular crosssection throughout substantially its entire length, and having helixes extending upward from the tapered end over a given length thereof, until the tapered end of the filler has reached the Apex of the tooth and the helixes have engaged essentially the apical one-third of the root canal.

Claim 3

A method of sealing the root canal of a tooth and implanting the tooth in the jaw bone of a patient to provide improvement of the crown-to-root ratio comprising the steps of removing portions of the tooth in axial alignment with the root canal of the tooth to be treated, to provide a longitudinal, generally cylindrical-shaped recess extending generally through the tooth; cleansing and preparing the cylindrical recess by inserting a sealing cement therein; inserting and rotating a tapered filler having helixes extending upward from the tapered end, said helixes forming two sets, said first set adjacent to the tapered end having adjacent helixes spaced farther apart than said second set adjacent to said first set, whereby said first set of helixes is securely implanted in the jaw bone of the patient, thereby providing improvement of the crown-to-root ratio by adding support to the tooth while insuring that a hermetic seal is maintained along the apical one-third of the root canal by said second set of helixes.

Claim 4

A method of sealing the root canal of a tooth and implanting the tooth in the jaw bone of a patient to provide improvement of the crown-to-root ratio comprising the steps of removing portions of the tooth in axial alignment with the root canal of the tooth to be treated, to provide a longitudinal, generally cylindrical-shaped recess extending generally through the tooth; cleansing and preparing the cylindrical recess by inserting a sealing cement therein; inserting and rotating a tapered filler having helixes extending upward from the tapered end, said helixes forming two sets, said first set adjacent to the tapered end having adjacent helixes spaced farther apart than said second set adjacent to said first set, whereby said first set of helixes is securely implanted in the jaw bone of the patient, thereby providing improvement of the crown-to-root ratio by adding support to the tooth while insuring that a hermetic seal is maintained along the apical one-third of the root canal by said second set of helixes.
