Anatomy relating device for dentists

Claim 2

An anatomy-relating device which comprises, means forming an insert adapted to be inserted between a person''s upper and lower teeth, said insert being made of a material which is generally formretaining but which will take a substantially permanent indentation responsive to biting pressure thereon, whereby to provide a substantially permanent record of a person''s interarch cusp-tip relationship, means forming a flap secured to said insert so that it can be swung between a position in extension of said insert and an upward position before a person''s face while the insert is so inserted, said flap being dimensioned to extend upwardly beyond a person''s interpupillary line and to extend laterally at least to a location adjacent a person''s pupils, said insert and flap having surface portions adapted to be marked with indicia of the location of a person''s midsagital plane and interpupillary line, said flap having an open central portion through which a person''s nose may project with said flap in said upward position.

Claim 3

The device defined in claim 1 wherein said inserT and flap are integrally formed of said material, said material being creased to form a hinged connection between said flap and insert.

Claim 4

The device defined in claim 1 and including in addition a second flap also secured to said insert so that it can be swung between a position in extension of said insert and an upward position, said second flap being disposed within said open portion when said two flaps are in corresponding ones of said positions, said second flap having surface portions adapted to be marked with indicia of the location of a person''s midsagital plane and having open portions which intersect said surface portions thereof to facilitate transferring the latter-said indicia to a model of a person''s dental arches.

Claim 5

The device defined in claim 3 wherein said insert and flaps are integrally formed of said material, said material being creased to form a hinged connection between said insert and each of said flaps.

Claim 6

The device defined in claim 4 wherein said hinged connections between said two flaps and said insert are substantially in mutual linear extension of each other.

Claim 7

The device defined in claim 3 wherein said open portions of said second flap comprise a series of openings arrayed along the length of said second flap.

Claim 8

The device defined in claim 5 wherein a portion of said material is severed to form said two flaps.

Claim 9

The device defined in claim 2 wherein said material comprises a flat sheet of expanded polystyrene.

Claim 10

The device defined in claim 7 wherein said material comprises a flat sheet of expanded polystyrene and the edge portions thereof are heat sealed to strengthen the same.

Claim 11

An anatomy-relating device which comprises, means forming an insert dimensioned and configured to be inserted into a person''s mouth and to be disposed between a person''s upper and lower teeth, said insert being formed of a material which is generally form-retaining but which will take a substantially permanent indentation responsive to biting pressure thereon, whereby to provide a substantially permanent record of a person''s interarch cusp-tip relationship, said material having a thickness of the order of about one-eighth inch and being indentable top and bottom responsive to said biting pressure to a depth adequate for fitting therein of the upper and lower cusp tips of a dental arch model, means forming a flap secured to said insert so that it can be swung between a position in extension of said insert and an upward position before a person''s face while the insert is so inserted, said flap being dimensioned to extend upwardly beyond a person''s interpupillary line and to extend laterally at least to a location adjacent a person''s pupils, said insert and flap having surface portions adapted to be marked with indicia of the location of a person''s midsagital plane and interpupillary line.

Claim 12

An anatomy-relating device which comprises, means forming an insert dimensioned and configured to be inserted into a person''s mouth and to be disposed between a person''s upper and lower teeth, said insert being formed of a material which is generally form-retaining but which will take a substantially permanent indentation responsive to biting pressure thereon, whereby to provide a substantially permanent record of a person''s interarch cusp-tip relationship, said material having a thickness of the order of about one-eighth inch and being indentable top and bottom responsive to said biting pressure to a depth adequate for fitting therein of the upper and lower cusp tips of a dental arch model, means forming a flap secured to said insert so that it can be swung between a position in extension of said insert and an upward position before a person''s face while the insert is so inserted, said flap being dimensioned to extend upwardly beyond a person''s interpupillary line and to extend laterally at least to a location adjacent a person''s pupils, said insert and flap having surface portions adapted to be marked with indicia of the location of a person''s midsagital plane and interpupillary line.
