Abstract
Abstract The invention described is for an instrument to place small objects a known distance and at a known angle from a given point and then releasing the object. It is particularly adapted for use in applying orthodontic brackets directly to teeth by means of a bonding compound. The instrument comprises a holder for the object, a release mechanism to release the object after placement and a positioning arm for precisely placing the object a measured distance from a given point. The instrument is housed in a small body adaptable to be easily held in the hand.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
170 words
A positioning device for placing orthodontic brackets on the labial surface of a tooth which comprises: a. an elongated body portion; b. holding means adapted to engage the bracket being placed on the surface of the tooth, said holding means being disposed at the forward end of said elongated body and fixedly held with respect thereto; c. guide means mounted to said forward end of said elongated body and adapted to engage the incisal edge of the tooth, said guide means being disposed a predetermined distance from said holding means so that the bracket may be accurately positioned on the labial surface of the tooth by appropriate positioning of said guide means, and d. means slidably mounted with respect to said elongated body and adapted to move parallel to the longitudinal axis thereof, said slidable means being movable with respect to said holding means so as to allow the bracket being positioned to be moved forwardly into engagement with the surface of the tooth and away from said holding means.
Claim 2
Dependent Claim
170 words
A positioning device for placing orthodontic brackets on the labial surface of a tooth which comprises: a. an elongated body portion; b. holding means adapted to engage the bracket being placed on the surface of the tooth, said holding means being disposed at the forward end of said elongated body and fixedly held with respect thereto; c. guide means mounted to said forward end of said elongated body and adapted to engage the incisal edge of the tooth, said guide means being disposed a predetermined distance from said holding means so that the bracket may be accurately positioned on the labial surface of the tooth by appropriate positioning of said guide means, and d. means slidably mounted with respect to said elongated body and adapted to move parallel to the longitudinal axis thereof, said slidable means being movable with respect to said holding means so as to allow the bracket being positioned to be moved forwardly into engagement with the surface of the tooth and away from said holding means.
Claim 3
Dependent Claim
25 words
A positioning device in accordance with claim 1 wherein said elongated body portion comprises a tubular open ended member having said slidable means disposed therein.
Claim 4
Dependent Claim
51 words
A positioning device in accordance with claim 2 wherein said slidable means has at the forward end thereof a grooved section for engagement with said holding means, and said holding means includes on at least a portion thereof a tongue adapted to slidably engage said grooved section of said slidable means.
Claim 5
Dependent Claim
39 words
A positioning device in accordance with claim 3 which further includes a spring member mounted on said slidable means and disposed within said tubular open ended elongated body so as to bias said slidable means toward the release position.
Claim 6
Dependent Claim
46 words
A positioning device in accordance with claim 4 wherein said guide means is adapted to be mounted at different angular orientations with respect to said holding means so as to allow the bracket to be positioned at various angles on the labial surface of a tooth.
Claim 7
Dependent Claim
163 words
A positioning device for placing orthodontic elements which comprises: a. an elongated body portion; b. holding means adapted to engage the element being placed, said holding means being disposed at the forward end of said elongated body and fixedly held with respect thereto; c. guide means mounted to said forward end of said elongated body and having a portion extending beyond said elongated body and holding means so as to act as a guide in positioning the orthodontic element; and d. means slidably mounted with respect to said elongated body and adapted to move parallel to the longitudinal axis thereof, said slidable means being movable with respect to said holding means so as to allow the element being positioned to be moved forwardly into the desired engagement and said holding means to be withdrawn from said element in a direction away from and perpendicular to the surface upon which the element is positioned by means of the movement of said slidably mounted means.
Claim 8
Dependent Claim
163 words
A positioning device for placing orthodontic elements which comprises: a. an elongated body portion; b. holding means adapted to engage the element being placed, said holding means being disposed at the forward end of said elongated body and fixedly held with respect thereto; c. guide means mounted to said forward end of said elongated body and having a portion extending beyond said elongated body and holding means so as to act as a guide in positioning the orthodontic element; and d. means slidably mounted with respect to said elongated body and adapted to move parallel to the longitudinal axis thereof, said slidable means being movable with respect to said holding means so as to allow the element being positioned to be moved forwardly into the desired engagement and said holding means to be withdrawn from said element in a direction away from and perpendicular to the surface upon which the element is positioned by means of the movement of said slidably mounted means.
Claim 9
Dependent Claim
224 words
A positioning device for placing orthodontic brackets on the labial surface of a tooth which comprises: a. a tubular open ended elongated body portion; b. holding means adapted to engage the bracket being placed on the surface of the tooth, said holding means being disposed at the forward end of said elongated body and fixedly held with respect thereto; c. guide means mounted to said forward end of said elongated body and adapted to engage the incisal edge of the tooth, said guide means being disposed a predetermined distance from said holding means so that the bracket may be accurately positioned on the labial surface of the tooth by appropriate positioning of said guide means; d. means slidably mounted within said tubular opend ended body adapted to move along the longitudinal axis of elongated body, said slidable means beIng movable with respect to said holding means so as to allow the bracket being positioned to be moved forwardly into engagement with the surface of the tooth and said holding means to be withdrawn from said bracket in a direction perpendicular to the surface of the tooth by means of the movement of said slidably mounted means; and e. a spring member mounted on said slidable means within said tubular open ended elongated body so as to bias said slidable means toward the release position.
Claim 10
Dependent Claim
224 words
A positioning device for placing orthodontic brackets on the labial surface of a tooth which comprises: a. a tubular open ended elongated body portion; b. holding means adapted to engage the bracket being placed on the surface of the tooth, said holding means being disposed at the forward end of said elongated body and fixedly held with respect thereto; c. guide means mounted to said forward end of said elongated body and adapted to engage the incisal edge of the tooth, said guide means being disposed a predetermined distance from said holding means so that the bracket may be accurately positioned on the labial surface of the tooth by appropriate positioning of said guide means; d. means slidably mounted within said tubular opend ended body adapted to move along the longitudinal axis of elongated body, said slidable means beIng movable with respect to said holding means so as to allow the bracket being positioned to be moved forwardly into engagement with the surface of the tooth and said holding means to be withdrawn from said bracket in a direction perpendicular to the surface of the tooth by means of the movement of said slidably mounted means; and e. a spring member mounted on said slidable means within said tubular open ended elongated body so as to bias said slidable means toward the release position.
