Abstract
Abstract The tray comprises two identical frames each open at the front and having a buccal frame member and a lingual frame member connected by a rear frame member. The buccal member at its forward end has a handle which, at its forward end, has a connecting portion. A clamp common to the frames detachably clamps the connecting portions in adjusted positions wherein the frames are spaced edgewise from each other in coplanar relation with the lingual members innermost. The frames can be adjusted edgewise by swinging them about the connecting portions and by moving the connecting portions bodily toward and away from each other. A sheet of soft, flexible woven sheet material bridges from the lingual to the buccal frame member of each frame. Each frame is composed of plastic with the members, handle, and connecting portion integral. The lateral margins of the sheet material are embedded in the plastic midway between the upper and lower surfaces of the frame.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
256 words
A device for introducing bite registration material between the occlusal surfaces of the teeth, and comprising a pair of open end frames; each frame having a buccal frame member, a lingual frame member spaced laterally therefrom, and a transverse end frame member at, and connecting, the rear ends of the buccal and lingual frame members, said buccal frame member having at its forward end a forwardly extending handle portion; a sheet of soft, flexible woven open mesh material bridging the space between the buccal and lingual frame members; characterized in that said members of each frame are of integral set soft resilient synthetic plastic material which can be cut readily with a knife, and the buccal and lingual frame members are unconnected at their forward ends so that the lingual frame member is readily resiliently flexible toward and away from the buccal frame member; said frames are free from buccal and lingual buttressing sidewall portions extending an appreciable distance from the plane of the sheet; said sheet has its lateral margins permanently bonded to the buccal and lingual frame members, respectively, by interpenetration of the plastic material with said lateral margins; said handle portion of each frame has at its forward end a connecting portion; and detachable clamp means common to the two connecting portions are provided and are operable to detachably engage the connecting portions in different adjusted relative positions, wherein the frames are spaced a selected position apart edgewise and are in coplanar relation, and to hold them firmly in said relatively adjusted positions.

Claim 3
Dependent Claim
44 words
The structure according to claim 1 wherein the connecting portions are of greater width than the handle portions and are accommodated in the clamp means in laterally spaced relation to each other for rotation about axes, respectively, normal to the plane of the frames.
Claim 4
Dependent Claim
34 words
The structure according to claim 1 wherein the margins of the sheet of material of each frame are embedded in the buccal and lingual frame members midway between the opposite surfaces of the frame.
Claim 5
Dependent Claim
49 words
The structure according to claim 3 wherein each frame is so shaped that it can be interchanged from a right-hand to left-hand position; and the frames are generally coplanar with each other when either frame is in the right-hand position and the other frame is in the left-hand position.
Claim 6
Dependent Claim
11 words
The structure according to claim 3 wherein the frames are duplicates.
Claim 7
Dependent Claim
174 words
A bite tray comprising an open end frame having: a buccal frame member, a lingual frame member spaced laterally therefrom, and a transverse end frame member at, and connecting, the rear ends of the buccal and lingual frame members; said buccal frame member having at its forward end a forwardly extending handle portion; a sheet of soft, flexible, organic, open mesh woven material bridging the space between the buccal and lingual frame members; characterized in that said members are integral, set soft resilient synthetic organic plastic material which can be cut readily with a knife, and the buccal and lingual frame members are unconnected at their anterior ends to that the lingual frame member is readily resiliently flexible toward and away from the buccal frame member; said frames are free from buttressing sidewall portions extending an appreciable distance from the plane of the sheet; the sheet is permanently bonded at its lateral margins to the buccal and lingual frame members, respectively, by interpenetration of the plastic material with said laterAl margins of the sheet.
Claim 8
Dependent Claim
174 words
A bite tray comprising an open end frame having: a buccal frame member, a lingual frame member spaced laterally therefrom, and a transverse end frame member at, and connecting, the rear ends of the buccal and lingual frame members; said buccal frame member having at its forward end a forwardly extending handle portion; a sheet of soft, flexible, organic, open mesh woven material bridging the space between the buccal and lingual frame members; characterized in that said members are integral, set soft resilient synthetic organic plastic material which can be cut readily with a knife, and the buccal and lingual frame members are unconnected at their anterior ends to that the lingual frame member is readily resiliently flexible toward and away from the buccal frame member; said frames are free from buttressing sidewall portions extending an appreciable distance from the plane of the sheet; the sheet is permanently bonded at its lateral margins to the buccal and lingual frame members, respectively, by interpenetration of the plastic material with said laterAl margins of the sheet.
Claim 9
Dependent Claim
74 words
The structure according to claim 6 wherein the frame members are of such thickness in a direct normal to plane of frame that the top of the frame is disposable below the occlusal surfaces of the teeth in the closing position of the bite; whereby the frame can fit around the outside of the lower teeth; and the handle portion is of greater thickness in said direction than the lingual and end frame members.
Claim 10
Dependent Claim
76 words
The structure according to claim 6 wherein the frame members are sufficiently stiff to support a charge of bite impression paste carried on the sheet without substantial lateral contraction due to the weight of the paste and to exert light lateral tension on the sheet, and the forward portion of the buccal frame member and of the handle contiguous thereto are more resistant to resilient flexure normal to the frame than is the lingual frame member.
Claim 11
Dependent Claim
28 words
The structure according to claim 6 wherein the margins of the sheet lie in a median plane substantially midway between the upper and lower faces of the frame.
