Abstract
Abstract A positioning fixture, or jig, adapted for use with conventional, off-the-shelf orthodontic appliance brackets and arch wires is shaped for optimum placement of the bracket on its associated tooth. Computer modeling of each tooth using digital scanning techniques allows each jig to be custom sized and shaped by CAD/CAM. The jig may be translucent for use with a light sensitive adhesive applied to the bracket to permit light curing of the adhesive. The jig may further be provided with one or more color-coded indicia such as for designating the arch and the particular tooth with which the jig is to be used. The jig may be further provided with elasticity to allow for deformation or failure of the jig to facilitate its removal and may also include an integral occlusal standoff extension to ensure proper in/out, or prominence, registration from the tooth's enamel surface as well as an alignment tab to ensure proper positioning of the jig on its associated tooth. The width of the jig may vary from the width of the appliance to the full width of the tooth itself, where the tooth lacks distinguishing anatomy. A set of jigs for a full set of teeth is packaged in a blister pack arrangement, with each jig attached to an associated removable brace for secure, fixed positioning within an individual upraised compartment of the blister pack. The jig may also span a gap between adjacent teeth for attaching an orthodontic bracket to one of the teeth where sufficient stabilization of the jig cannot be achieved by engaging the target tooth alone.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
102 words
Apparatus for attaching an orthodontic bracket to a tooth of a patient by means of an adhesive, said apparatus comprising: a housing; a first recessed portion of said housing for receiving and engaging the tooth in a tight-fitting manner; a second recessed portion of said housing for receiving and engaging the orthodontic bracket and for securely maintaining the orthodontic bracket in contact with an adhesive on a lateral surface of the tooth; and a standoff projection attached to and extending from said housing for engaging the tooth and providing a predetermined stand-off spacing between the housing and the surface of the tooth.
Claim 2
Dependent Claim
102 words
Apparatus for attaching an orthodontic bracket to a tooth of a patient by means of an adhesive, said apparatus comprising: a housing; a first recessed portion of said housing for receiving and engaging the tooth in a tight-fitting manner; a second recessed portion of said housing for receiving and engaging the orthodontic bracket and for securely maintaining the orthodontic bracket in contact with an adhesive on a lateral surface of the tooth; and a standoff projection attached to and extending from said housing for engaging the tooth and providing a predetermined stand-off spacing between the housing and the surface of the tooth.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1 wherein said housing has a width substantially equal to the mesial-distal width of said tooth for secure mounting of said housing on a tooth generally lacking a distinguishing anatomy.
Claim 4
Dependent Claim
20 words
The apparatus of claim 1 wherein said housing has a width substantially equal to the width of the orthodontic bracket.
Claim 5
Dependent Claim
23 words
The apparatus of claim 1 wherein said standoff projection engages the tooth intermediate the orthodontic bracket and an incisal edge of the tooth.
Claim 6
Dependent Claim
20 words
The apparatus of claim 1 wherein the adhesive is cured by light incident thereon and wherein said housing is translucent.
Claim 7
Dependent Claim
26 words
The apparatus of claim 5 wherein the adhesive is responsive to blue light transmitted through said housing and incident upon the adhesive for the curing thereof.
Claim 8
Dependent Claim
28 words
The apparatus of claim 1 further comprising a handle coupled to said housing to facilitate the manipulation of the housing during installation on and removal from a tooth.
Claim 9
Dependent Claim
12 words
The apparatus of claim 7 wherein said handle includes an aperture therein.
Claim 10
Dependent Claim
36 words
The apparatus of claim 1 wherein said housing includes a weakened portion capable of deforming or breaking under stress to facilitate removal of the housing from a tooth after attaching an orthodontic bracket to the tooth.
Claim 11
Dependent Claim
16 words
The apparatus of claim 9 wherein said weakened portion is characterized as having a reduced thickness.
Claim 12
Dependent Claim
32 words
The apparatus of claim 1 wherein said first recessed portion includes mesial, distal and lingual portions for engaging the tooth's mesial and distal occlusal corners and a lingual surface of the tooth.
Claim 13
Dependent Claim
43 words
The apparatus of claim 1 wherein said housing further includes a third recessed portion for engaging a second adjacent tooth, wherein a gap is disposed intermediate the teeth and said housing is stabilized for more securely attaching the housing to the first tooth.
Claim 14
Dependent Claim
28 words
The apparatus of claim 1 further comprising color-coded means disposed on said housing for indicating the location of the patient's mouth where the apparatus is to be installed.
Claim 15
Dependent Claim
44 words
The apparatus of claim 13 wherein said color-coded means indicates the arch in which the apparatus is intended for use, the portion of said arch in which the apparatus is intended for use, and the tooth with which the apparatus is intended for use.
Claim 16
Dependent Claim
15 words
The apparatus of claim 13 wherein said color-coded means comprises the color of said housing.
Claim 17
Dependent Claim
27 words
The apparatus of claim 15 wherein said color-coded means further includes one or more designated portions on the surface of said housing each having a respective color.
Claim 18
Dependent Claim
134 words
Apparatus for attaching an orthodontic bracket to a tooth of a patient by means of an adhesive, said apparatus comprising: a housing; a first recessed portion of said housing for receiving and engaging the tooth in a tight-fitting manner; a second recessed portion of said housing for receiving and engaging a distal surface portion of the orthodontic bracket and for securely maintaining the orthodontic bracket in contact with an adhesive on a lateral surface of the tooth; and positioning stop means in said second recessed portion for engaging the orthodontic bracket when the orthodontic bracket is in contact with said adhesive on a lateral surface of the tooth and ensuring proper positioning of the orthodontic bracket in said housing, wherein said positioning stop means restricts mesial-distal movement between the orthodontic bracket and said housing.
Claim 19
Dependent Claim
134 words
Apparatus for attaching an orthodontic bracket to a tooth of a patient by means of an adhesive, said apparatus comprising: a housing; a first recessed portion of said housing for receiving and engaging the tooth in a tight-fitting manner; a second recessed portion of said housing for receiving and engaging a distal surface portion of the orthodontic bracket and for securely maintaining the orthodontic bracket in contact with an adhesive on a lateral surface of the tooth; and positioning stop means in said second recessed portion for engaging the orthodontic bracket when the orthodontic bracket is in contact with said adhesive on a lateral surface of the tooth and ensuring proper positioning of the orthodontic bracket in said housing, wherein said positioning stop means restricts mesial-distal movement between the orthodontic bracket and said housing.
