Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
143 words
An artificial tooth supporter for supporting artificial teeth when they are subjected to heat treating comprising a base plate formed with at least one recess in its upper surface, at lease one cylindrical column vertically upwardly projecting from the upper surface of the base plate, at least one movable member formed with a circular hole to be complementarily and detachably engaged with the column so that the movable member can be rotated about the column on the upper surface of the base plate, and first and second artificial tooth supporting pins for supporting the artificial teeth on their upper ends, said first supporting pin being upwardly projecting from the movable member and spaced from the circular hole, and said second supporting pin having at its lower end a fitting portion to be frictionally and detachably inserted into the recess of the base plate.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
17 words
An artificial tooth supporter according to claim 1, which is made of a heat resistant inorganic material.
Claim 4
Dependent Claim
15 words
An artificial tooth supporter according to claim 2, which consists essentially of alumina and alundum.
Claim 5
Dependent Claim
22 words
An artificial tooth supporter according to claim 1, wherein said cylindrical column has at its upper end an artificial tooth supporting section.
Claim 6
Dependent Claim
18 words
An artificial tooth supporter according to claim 1, wherein said column is integrally formed with the base plate.
Claim 7
Dependent Claim
21 words
An artificial tooth supporter according to claim 1 in which said second supporting pin has a conical artificial tooth supporting section.
Claim 8
Dependent Claim
21 words
An artificial tooth supporter according to claim 1 in which said second supporting pin has a wedge-like artificial tooth supporting section.
Claim 9
Dependent Claim
21 words
An artificial tooth supporter according to claim 1 in which said second supporting pin has a cylindrical artificial tooth supporting section.
Claim 10
Dependent Claim
19 words

Claim 11
Dependent Claim
27 words
An artificial tooth supporter according to claim 1 in which said base plate has at least one cutout on the other side surface of the base plate.
Claim 12
Dependent Claim
134 words
An artificial tooth supporter for supporting dental bridges when they are subjected to heat treating comprising a base plate, at least one cylindrical column vertically projecting from the upper surface of the base plate, at least one movable member formed with a circular hole complementary with the column and a first artificial tooth supporting pin upwardly projecting from the movable member and spaced from the circular hole, said movable member being adapted to be detachably engaged with the column through the hole and rest on the upper surface of the base plate, and at least one second artificial tooth supporting pin upwardly projecting from the base plate, whereby the dental bridge is supported on the first and second supporting pins so that the movable member is held at position by the dental bridge itself.
Claim 13
Dependent Claim
134 words
