Abstract
Abstract The mold in question includes a cup (1) of transparent material strengthened by a single or multiple reinforcement (2, 2', 3) of wire or metal strip incorporated in the plastic of the cap. The cap (1) or reinforcement ends above in a stem (1') which makes it possibe to grasp the mold and hold it in place for the entire time of polymerization of the filling mastic performed by ultraviolet or visible light rays. This mold is particularly suited for giving the exact shape of the filling of front teeth, both on the right and left side.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
90 words
Angular mold for dental use comprising a cap of material transparent to ultraviolet rays and the rays of the visible solar spectrum to allow the rapid hardening, by polymerization even for two-component filling materials, of the filling mastic and material that does not adhere to said filling mastic, characterized in that said cap is strengthened by a reinforcement (2, 3) and the cap or reinforcement is provided with a stem that makes it possible to grasp the mold without blocking passage of the rays that cause polymerization or the mastic.
Claim 2
Dependent Claim
90 words
Angular mold for dental use comprising a cap of material transparent to ultraviolet rays and the rays of the visible solar spectrum to allow the rapid hardening, by polymerization even for two-component filling materials, of the filling mastic and material that does not adhere to said filling mastic, characterized in that said cap is strengthened by a reinforcement (2, 3) and the cap or reinforcement is provided with a stem that makes it possible to grasp the mold without blocking passage of the rays that cause polymerization or the mastic.
Claim 3
Dependent Claim
10 words
Mold as in claim 1, wherein the reinforcement is metallic.
Claim 4
Dependent Claim
41 words
Mold as in claim 1 and 2, wherein said reinforcement is fork-shaped with a V progression (2, 2'), is single or multiple and buried in the transparent plastic of the cap (1), a transparent material that extends into a handle (1').
Claim 5
Dependent Claim
33 words
Mold as in claim 3, wherein said V reinforcement is in the shape of a wire or strap and its branches are shaped to fit the profile of the tooth to be filled.
Claim 6
Dependent Claim
26 words
Mold as in claim 4, wherein said reinforcement consists of a fork located forward with respect to the cap, i.e., in the vicinity of its opening.
Claim 7
Dependent Claim
20 words
Mold as in claim 4, wherein said reinforcement consists of a fork located in the center line of said cap.
Claim 8
Dependent Claim
19 words
Mold as in claim 4, wherein said reinforcement consists of a fork located at the base of said cap.
Claim 9
Dependent Claim
26 words
Mold as in claim 4, wherein said reinforcement consists of two forks with one located at the opening, the other at the base of said cap.
Claim 10
Dependent Claim
26 words
Mold as in claims 4 to 8, wherein said reinforcement is shaped to be inserted on the right or left of the tooth to be filled.
Claim 11
Dependent Claim
26 words
Mold as in claim 4, wherein said reinforcement is symmetrical, i.e., shaped to be inserted on the right or left of the tooth to be filled.
Claim 12
Dependent Claim
12 words
Mold as in claims 1 to 10, wherein said reinforcement is plastic.
Claim 13
Dependent Claim
25 words
Mold as in claims 1 to 10, wherein said fork is of a metallic material permanently deformable by crushing against the tooth to be filled.
Claim 14
Dependent Claim
20 words
Mold as in claim 1, wherein said reinforcement consists of a net immersed in the trasparent material of the cap.
Claim 15
Dependent Claim
29 words
Mold as in claims 1 to 13, wherein said reinforcement is further strengthened or replaced by a metallic net or by a metallic or nonmetallic sheet with small holes.
