Abstract
Abstract Spring wire devices inserted between maxillary and mandibular molars for separating impacted molars by crimping an activating loop portion of the device projecting at an angle to separating arms inserted between the teeth. The separating arms are interconnected with the activating loop by deflector formations adapted to bridge the space between the teeth and retain the device in place until removed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
110 words
A device adapted to be inserted between adjacent teeth for separating the same, comprising a pair of spaced separating arms extending in substantially coplanar relation to each other prior to deformation, terminal means respectively carried by said arms and adapted to be inserted between said adjacent teeth on buccal and lingual sides thereof respectively, a pair of deflectors extending toward each other from said arms and spaced from terminal means, deformation responsive activating means interconnecting the deflectors and extending therefrom at an angle to the separating arms for displacement of the deflectors and terminal means into laterally overlapping relationship to each other to exert separating forces on the adjacent teeth.
Claim 2
Independent Claim
110 words
A device adapted to be inserted between adjacent teeth for separating the same, comprising a pair of spaced separating arms extending in substantially coplanar relation to each other prior to deformation, terminal means respectively carried by said arms and adapted to be inserted between said adjacent teeth on buccal and lingual sides thereof respectively, a pair of deflectors extending toward each other from said arms and spaced from terminal means, deformation responsive activating means interconnecting the deflectors and extending therefrom at an angle to the separating arms for displacement of the deflectors and terminal means into laterally overlapping relationship to each other to exert separating forces on the adjacent teeth.
Claim 3
Dependent Claim
17 words
The combination of claim 1 wherEin said device is formed from a single length of elongated wire.
Claim 4
Dependent Claim
32 words
The combination of claim 2 wherein said deflectors bridge the separating arms in response to deformation of the activating means to retain the device in place by occlusal contact with said teeth.
Claim 5
Dependent Claim
43 words
The combination of claim 3 wherein said activating means comprises a deformable activating loop responsive to crimping for effecting said displacement of the deflectors and the terminal means relative to each other and folded into occlusal contact with one of the adjacent teeth.
Claim 6
Dependent Claim
17 words
The combination of claim 4 wherein said teeth are molars and/or bicuspids, one of which is impacted.
Claim 7
Dependent Claim
32 words
The combination of claim 1 wherein said deflectors bridge the separating arms in response to deformation of the activating means to retain the device in place by occlusal contact with said teeth.
Claim 8
Dependent Claim
43 words
The combination of claim 6 wherein said activating means comprises a deformable activating loop responsive to crimping for effecting said displacement of the deflectors and the terminal means relative to each other and folded into occlusal contact with one of the adjacent teeth.
Claim 9
Dependent Claim
43 words
The combination of claim 1 wherein said activating means comprises a deformable activating loop responsive to crimping for effecting said displacement of the deflectors and the terminal means relative to each other and folded into occlusal contact with one of the adjacent teeth.
Claim 10
Independent Claim
116 words
A device adapted to be inserted between adjacent teeth for separating the same comprising an elongated wire having a pair of spaced separating arms disposed in coplanar relation to a common plane, said arms being formed with terminal loops at ends closely spaced from each other, deflector formations extending toward each other from ends of the arms more widely spaced from each other in said common plane, and an activating loop interconnecting the deflector formations and extending therefrom at an obtuse angle to said common plane, said activating loop having a deformable bridging portion responsive to crimping for causing displacement of the deflector formations and the terminal loops into overlapping relationship laterally of said common plane.
Claim 11
Independent Claim
116 words
A device adapted to be inserted between adjacent teeth for separating the same comprising an elongated wire having a pair of spaced separating arms disposed in coplanar relation to a common plane, said arms being formed with terminal loops at ends closely spaced from each other, deflector formations extending toward each other from ends of the arms more widely spaced from each other in said common plane, and an activating loop interconnecting the deflector formations and extending therefrom at an obtuse angle to said common plane, said activating loop having a deformable bridging portion responsive to crimping for causing displacement of the deflector formations and the terminal loops into overlapping relationship laterally of said common plane.
