Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
78 words
An assembly for the custom formation of a dental shade guide tab comprising a hollow transparent substantially closed mold and stick-like handle, said substantially closed mold having an opening in which selected raw tooth filling restorative material is located to harden and cure in the shape of said mold, said handle having anchor means projecting through said opening and into anchoring engagement with the restorative material, and said mold being separable from said restorative material and said handle.
Claim 2
Dependent Claim
78 words
An assembly for the custom formation of a dental shade guide tab comprising a hollow transparent substantially closed mold and stick-like handle, said substantially closed mold having an opening in which selected raw tooth filling restorative material is located to harden and cure in the shape of said mold, said handle having anchor means projecting through said opening and into anchoring engagement with the restorative material, and said mold being separable from said restorative material and said handle.
Claim 3
Dependent Claim
17 words
The assembly according to claim 1 wherein said mold and said handle are separated from each other
Claim 4
Dependent Claim
73 words
The assembly according to claim 1 wherein said mold and said handle are integrally formed and joined together with said jointure forming a line of reduced strength along which said handle and mold may be bent relative to each other to project said anchor means on said handle through said opening and into the restorative material in said mold and for separation thereat of said mold from the restorative material and said handle.
Claim 5
Dependent Claim
21 words
The assembly according to claim 1 wherein said anchor means being substantially button shaped has an enlarged head and a stem
Claim 6
Dependent Claim
20 words
The assembly according to claim 4, wherein said mold is of plastics and is separable from said hardened filling material.
Claim 7
Independent Claim
88 words
The method for forming a dental shade guide comprising the steps of providing a hollow transparent plastics mold, filling the hollow of the mold with a selected raw material to cure and harden therein, providing the mold with a handle to manipulate the hardened filling material by inserting anchor means on the handle into the filling material before the material hardens to join the handle and the filling material after the filling material hardens, and removing the transparent plastic mold from the filling material after the same hardens.
Claim 8
Independent Claim
88 words
The method for forming a dental shade guide comprising the steps of providing a hollow transparent plastics mold, filling the hollow of the mold with a selected raw material to cure and harden therein, providing the mold with a handle to manipulate the hardened filling material by inserting anchor means on the handle into the filling material before the material hardens to join the handle and the filling material after the filling material hardens, and removing the transparent plastic mold from the filling material after the same hardens.
Claim 9
Dependent Claim
58 words
The method according to claim 6 including the step of attaching the anchor means having the form of a substantial button shape extending from the handle at least in part into the filling material before it hardens and cures, and rotating the button in the filling material before it hardens and cures to provide a rotatable joint therebetween.
Claim 10
Dependent Claim
33 words
The method according to claim 7, forming the mold and handle separately, and inserting the anchor means into the mold through an opening in the rear thereof to receive the anchor means therethrough.
Claim 11
Independent Claim
111 words
The method of making a dental shade guide tab comprising making a body of dental filling material in the shape of an upper incisor tooth resulting from the insertion of raw tooth colored dental filling material within a transparent mold shell, providing a handle with an anchor member integrally formed with the handle and inserting the same into the body of raw material prior to hardening so as to be anchored thereto upon hardening, allowing the material to harden within the mold shell, moving the handle relative to the body of material to provide for relative movement therebetween, removing the mold shell from the body after hardening to expose the body.
Claim 12
Independent Claim
111 words
The method of making a dental shade guide tab comprising making a body of dental filling material in the shape of an upper incisor tooth resulting from the insertion of raw tooth colored dental filling material within a transparent mold shell, providing a handle with an anchor member integrally formed with the handle and inserting the same into the body of raw material prior to hardening so as to be anchored thereto upon hardening, allowing the material to harden within the mold shell, moving the handle relative to the body of material to provide for relative movement therebetween, removing the mold shell from the body after hardening to expose the body.
Claim 13
Dependent Claim
41 words
The method of making a shade guide tab according to claim 9, bending the handle relative to the mold shell to anchor it to the body of material in the mold, and separating the handle and mold shell from each other.
Claim 14
Independent Claim
103 words
The method of forming a dental shade guide comprising the steps of providing a hollow transparent plastics mold, filling the mold with a selected raw material to cure and harden, providing the mold with a handle to manipulate the hardened filling material, attaching the handle at least in part to the cured or hardened material and thereafter removing the mold to expose the cured or hardened material, and forming the mold and the handle unitary with a separable joint and providing the same with portions of reduced strength along their joining portions whereby the mold and handle may be separated from each other.
