Abstract
Abstract A molar tube appliance including a molar or buccal tube for mounting on a molar and for receiving a lip bumper or a face bow, wherein the tube has a flared opening with the larger end of the opening being at the mesial end. The opening is structured to enhance insertion of the lip bumper or face bow by the patient particularly where the molar is adversely rotated.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
189 words
A molar tube for a lip bumper or a face bow comprising, a base having a lingually facing attaching surface for attaching to a tooth, an elongated mesialdistally extending tubular body projecting buccally from said base, said body including an opening therethrough for receiving the distal ends of a lip bumper or a face bow and having an inside lingual wall and an outside buccal wall, said opening being flared from the distal end to the mesial end such that the mesial end is larger than the distal end and of a size substantially larger than the distal end of a lip bumper or a face bow, said distal end of the opening being round and sized to closely receive the distal end of the lip bumper or face bow to provide lateral control, said mesial end being oval and having a vertical dimension to closely receive the distal end of the lip bumper or face bow to control tipping, and the long axis of the oval mesial end extending generally horizontally, whereby insertion of a distal end of a lip bumper or a face bow is greatly enhanced.
Claim 2
Dependent Claim
189 words
A molar tube for a lip bumper or a face bow comprising, a base having a lingually facing attaching surface for attaching to a tooth, an elongated mesialdistally extending tubular body projecting buccally from said base, said body including an opening therethrough for receiving the distal ends of a lip bumper or a face bow and having an inside lingual wall and an outside buccal wall, said opening being flared from the distal end to the mesial end such that the mesial end is larger than the distal end and of a size substantially larger than the distal end of a lip bumper or a face bow, said distal end of the opening being round and sized to closely receive the distal end of the lip bumper or face bow to provide lateral control, said mesial end being oval and having a vertical dimension to closely receive the distal end of the lip bumper or face bow to control tipping, and the long axis of the oval mesial end extending generally horizontally, whereby insertion of a distal end of a lip bumper or a face bow is greatly enhanced.
Claim 3
Dependent Claim
47 words
The buccal tube of claim 1, wherein the inside lingual wall of said opening is generally parallel to the base and the outside buccal wall of said opening extends at an angle to the base with the included angle being at the distal end of said opening.
Claim 4
Dependent Claim
47 words
The buccal tube of claim 1, wherein the outside buccal wall of the opening is generally parallel to the base and the inside lingual wall of said opening extends at an angle to the base with the included angle being at the mesial end of the opening.
Claim 5
Dependent Claim
60 words
The buccal tube of claim 1, wherein the outside buccal wall of said opening extends at an angle to the base with the included angle being at the distal end of the opening, and the inside lingual wall of said opening extends at an angle to the base with the included angle being at the mesial end of the opening.
Claim 6
Dependent Claim
24 words
The buccal tube of claim 1, wherein the opening is distally offset such that the lingual wall extends at an angle to the base.
Claim 7
Dependent Claim
33 words
The buccal tube of claim 1, wherein the inside lingual wall of the opening is distally offset from the base, and the outside buccal wall of the opening is parallel from the base.
Claim 8
Dependent Claim
173 words
In combination with a base having a buccal tube for receiving a main archwire, said buccal tube adapted to be mounted on the buccal face of a molar tooth, means for receiving a distal end of a lip bumper or a face bow, the improvement in said means which includes an elongated tube carried by said base having a mesial-distally extending opening, said opening having a mesial end and a distal end and being flared from the distal end to the mesial end, the mesial end being substantially larger than the distal end and oval shaped to facilitate insertion of the lip bumper or face bow particularly when the molar tooth is adversely rotated, and the distal end being round to closely receive the distal end of the lip bumper or face bow and provide lateral control, the long axis of the oval-shaped mesial end extending generally horizontally and the vertical dimension of the opening being sized to closely receive the distal end of the lip bumper or face bow to control tipping.
Claim 9
Dependent Claim
173 words
In combination with a base having a buccal tube for receiving a main archwire, said buccal tube adapted to be mounted on the buccal face of a molar tooth, means for receiving a distal end of a lip bumper or a face bow, the improvement in said means which includes an elongated tube carried by said base having a mesial-distally extending opening, said opening having a mesial end and a distal end and being flared from the distal end to the mesial end, the mesial end being substantially larger than the distal end and oval shaped to facilitate insertion of the lip bumper or face bow particularly when the molar tooth is adversely rotated, and the distal end being round to closely receive the distal end of the lip bumper or face bow and provide lateral control, the long axis of the oval-shaped mesial end extending generally horizontally and the vertical dimension of the opening being sized to closely receive the distal end of the lip bumper or face bow to control tipping.
Claim 10
Dependent Claim
44 words
The means of claim 7, wherein the lingual wall of the opening is generally parallel to the base and the buccal wall of the opening extends at an angle to the base with the included angle being at the distal end of the opening.
Claim 11
Dependent Claim
23 words
The means of claim 7, wherein the opening is distally offset such that the lingual wall extends at an angle to the base.
Claim 12
Dependent Claim
44 words
The means of claim 7, wherein the outside wall of the opening is generally parallel to the base and the inside wall of said opening extends at an angle to the base with the included angle being at the mesial end of the opening.
