Abstract

A dental apparatus usable for root canal procedures in conjunction with a dental clamp includes a first base member, a second base member spaced apart from the first base member, a first reference member extending between the first and second base members and connecting the first and second base members to one another, the first reference member extending in a first direction relative to an imaginary plane extending across the first and second base members, a second reference member extending between the first and second base members and connecting the first and second base members to one another, the second reference member being spaced apart from the first reference member, a first post extending from the first base member in a second direction relative to the imaginary plane, opposite to the first direction, and a second post extending from the second base member in the second direction.

First claim

What is claimed is:

1. A method of using a dental assembly, comprising:
obtaining a dental clamp, said dental clamp including a first clamping portion and a second clamping portion, the first and second clamping portions being configured to releasably clamp the dental clamp to a tooth, wherein the first clamping portion has a first through hole and the second clamping portion has a second through hole;
selectively connecting the dental clamp to a tooth of a patient;
obtaining a dental apparatus, said dental apparatus including:
a first base member;
a second base member spaced apart from the first base member;
a first reference member extending between the first and second base members and directly connecting the first and second base members to one another, the first reference member extending in a first direction relative to an imaginary plane that extends across the first and second base members;
a second reference member extending between the first and second base members and directly connecting the first and second base members to one another, the second reference member extending in the first direction relative to the imaginary plane, the second reference member being spaced apart from the first reference member;
a first post extending from the first base member in a second direction relative to the imaginary plane, opposite to the first direction; and
a second post extending from the second base member in the second direction relative to the imaginary plane,
wherein the first post is configured to be inserted in the first through hole of the first clamping portion to selectively connect the dental clamp and the dental apparatus to one another, and
wherein the second post is configured to be inserted in the second through hole of the second clamping portion to selectively connect the dental clamp and the dental apparatus to one another;

selectively connecting the dental apparatus to the dental clamp to one another by inserting the first post in the first through hole and the second post in the second through hole;
inserting a dental file inside of a root canal of the tooth, the inserting of the dental file inside of the root canal causes the dental file to intersect with a first beam of the first reference member; and
using the intersection between the dental file and the first beam as a reference point for determining a length of the root canal or as a reference point for determining a maximum depth of insertion of the file in the root canal.

2. The method of claim 1 , wherein the first reference member includes a third post extending from the first base member in the first direction, a fourth post extending from the second base member in the first direction, and the first beam connecting the third and fourth posts to one another, the first beam being spaced from the first and second base members in the first direction.

3. The method of claim 2 , wherein at least one selected from the group consisting of the third post, the fourth post and the first beam is straight.

4. The method of claim 2 , wherein the first beam is straight.

5. The method of claim 2 , wherein the second reference member includes a fifth post extending from the first base member in the first direction, a sixth post extending from the second base member in the first direction, and a second beam connecting the fifth and sixth posts to one another, the second beam being spaced from the first and second base members in the first direction.

6. The method of claim 5 , wherein at least one selected from the group consisting of the fifth post, the sixth post and the second beam is straight.

7. The method of claim 5 , wherein the second beam is straight.

8. The method of claim 5 , wherein the first and second beams extend in parallel to one another.

9. The method of claim 5 , wherein the first and second beams are disposed at a same height relative to the imaginary plane.

10. The method of claim 1 , wherein the first post includes a first protrusion at an end thereof that is distal to the first base member, the first protrusion being wider than the first post.

11. The method of claim 10 , wherein the second post includes a second protrusion at an end thereof that is distal to the second base member, the second protrusion being wider than the second post.
