Abstract
Abstract A method of measuring the position of the teeth prior to orthodontic treatment, whereby a mouthpiece which is connected to a gauge through a series of universal and rotational joints, is inserted into the patient''s mouth and grasped by the lips, the lips then exerting a pulling force on the gauge to provide a measurement of maximum lip force which, in turn, provides an indication of the position of the teeth.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
145 words
A method of measuring the maximum strength of the lips of a patient without the interposition of other forces, the maximum strength of the lips influencing the position of the incisor teeth in the patient''s mouth, which comprises causing the patient to bring his teeth into occlusal contact, inserting a mouthpiece, connected to a gauge by a universal joint, between the lips of the patient in such a manner that the mouthpiece contacts the labial surface of the maxillary incisors in the patient''s mouth, causing the patient to close his lips so that only the lips grasp the mouthpiece, causing the patient to pull back his head while the mouthpiece is grasped only by the lips and while the gauge is free from the action of other forces due to said universal joint, and recording the force of pull of the lips on the gauge.
Claim 2
Independent Claim
145 words
A method of measuring the maximum strength of the lips of a patient without the interposition of other forces, the maximum strength of the lips influencing the position of the incisor teeth in the patient''s mouth, which comprises causing the patient to bring his teeth into occlusal contact, inserting a mouthpiece, connected to a gauge by a universal joint, between the lips of the patient in such a manner that the mouthpiece contacts the labial surface of the maxillary incisors in the patient''s mouth, causing the patient to close his lips so that only the lips grasp the mouthpiece, causing the patient to pull back his head while the mouthpiece is grasped only by the lips and while the gauge is free from the action of other forces due to said universal joint, and recording the force of pull of the lips on the gauge.
Claim 3
Dependent Claim
148 words
A measurement device for measuring the maximum strength of the lips which, in turn, influences the position of the incisor teeth in a patient''s mouth comprising a support, a gauge for measuring linear strains mounted on said support, said gauge having a dial including a pointer, a rod means operatively connected to said pointer, said rod means having at least a portion thereof slidably positioned in a guide means mounted on said support, and a mouthpiece connected to said rod means, said rod means comprising at least two rod portions connected to each other by a universal joint, said rod means comprising a first rod protion operatively connected to said pointer, a second rod portion connected to said first rod portion by a universal joint, and a third rod portion connected to said second rod portion by a universal joint, said mouthpiece being connected to said rod portion.
Claim 4
Dependent Claim
148 words
A measurement device for measuring the maximum strength of the lips which, in turn, influences the position of the incisor teeth in a patient''s mouth comprising a support, a gauge for measuring linear strains mounted on said support, said gauge having a dial including a pointer, a rod means operatively connected to said pointer, said rod means having at least a portion thereof slidably positioned in a guide means mounted on said support, and a mouthpiece connected to said rod means, said rod means comprising at least two rod portions connected to each other by a universal joint, said rod means comprising a first rod protion operatively connected to said pointer, a second rod portion connected to said first rod portion by a universal joint, and a third rod portion connected to said second rod portion by a universal joint, said mouthpiece being connected to said rod portion.
Claim 5
Dependent Claim
89 words
The device of claim 2 wherein the universal joint between the first and second rod portions comprises a hook having a stem portion, said stem portion extending loosely through an aperture in a hollow sleeve mounted on said first rod portion, said stem portion having a ball on that end which is within said sleeve to provide a ball and socket connection, said hook being slidably connected to a ring, and said ring being loosely positioned in an aperture in the corresponding end portion of said second rod portion.
Claim 6
Dependent Claim
22 words
The device of claim 3 wherein the universal joint between the second and third rod portions comprises a ball and socket connection.
Claim 7
Dependent Claim
109 words
A measurement device for measuring the maXimum strength of the lips which, in turn, influences the position of the incisor teeth in a patient''s mouth comprising a support, a gauge for measuring linear strains mounted on said support. said gauge having a dial including a pointer, a rod means operatively connected to said pointer, said rod means having at least a portion thereof slidably positioned in a guide means mounted on said support, and a mouthpiece connected to said rod means, said means comprising at least two rod portions connected to each other by a universal joint, said mouthpiece being connected to said rod means by a rotatable connection.
Claim 8
Dependent Claim
109 words
A measurement device for measuring the maXimum strength of the lips which, in turn, influences the position of the incisor teeth in a patient''s mouth comprising a support, a gauge for measuring linear strains mounted on said support. said gauge having a dial including a pointer, a rod means operatively connected to said pointer, said rod means having at least a portion thereof slidably positioned in a guide means mounted on said support, and a mouthpiece connected to said rod means, said means comprising at least two rod portions connected to each other by a universal joint, said mouthpiece being connected to said rod means by a rotatable connection.
Claim 9
Dependent Claim
120 words
A measurement device for measuring the maximum strength of the lips which, in turn, influences the position of the incisor teeth in a patient''s mouth comprising a support, a gauge for measuring linear strains mounted on said support, said gauge having a dial including a pointer, a rod means operatively connected to said pointer, said rod means having at least a portion thereof slidably positioned in a guide means mounted on said support, and a mouthpiece connected to said rod means, said rod means comprising at least two rod portions connected to each other by a universal joint, said mouthpiece comprising an elongated plate having concave edges between the opposed ends thereof, and a transverse flange on its free end.
Claim 10
Dependent Claim
120 words
A measurement device for measuring the maximum strength of the lips which, in turn, influences the position of the incisor teeth in a patient''s mouth comprising a support, a gauge for measuring linear strains mounted on said support, said gauge having a dial including a pointer, a rod means operatively connected to said pointer, said rod means having at least a portion thereof slidably positioned in a guide means mounted on said support, and a mouthpiece connected to said rod means, said rod means comprising at least two rod portions connected to each other by a universal joint, said mouthpiece comprising an elongated plate having concave edges between the opposed ends thereof, and a transverse flange on its free end.
