Abstract
Abstract An improved adjustable attachment for a labial arch retainer. The retainer is of the type having a palatal section configured to conform to the roof of the mouth of a patient, a pair of extension wires extending anterially from the palatal section, an attachment hook provided at the terminal end of each extension wire, and a resilient synthetic band adapted to exert pressure against the teeth of the patient. The adjustable attachment is connected between the resilient band and the attachment hook in a manner which permits the length of the resilient band to be varied thereby permitting adjustment of the pressure exerted against the teeth of the patient.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
In a labial arch retainer of the type having a palatal section configured to closely conform to the roof of the mouth of a user, tooth engaging means extending from the palatal section to maintain the retainer in place, band attachment means provided in the tooth engaging means, and a resilient band connectable to the band attachment means to apply retention forces upon the teeth of the user, an improved band connector which comprises a central body having means for connecting the body to the resilient band and a longitudinal extension having a plurality of spaced means for engaging the band attachment means, wherein the band attachment means is adapted to adjustably lock the band to the band attachment means.
Claim 2
Dependent Claim
120 words
In a labial arch retainer of the type having a palatal section configured to closely conform to the roof of the mouth of a user, tooth engaging means extending from the palatal section to maintain the retainer in place, band attachment means provided in the tooth engaging means, and a resilient band connectable to the band attachment means to apply retention forces upon the teeth of the user, an improved band connector which comprises a central body having means for connecting the body to the resilient band and a longitudinal extension having a plurality of spaced means for engaging the band attachment means, wherein the band attachment means is adapted to adjustably lock the band to the band attachment means.
Claim 3
Dependent Claim
19 words
The retainer of claim 1 wherein the means for connecting is adapted to be crimped onto the resilient band.
Claim 4
Dependent Claim
41 words
The retainer of claim 2 wherein the means for connecting has a plurality of fingers extending outwardly from the body, the fingers being adapted to bend over the resilient band to thereby affix the means for connecting to the resilient band.
Claim 5
Dependent Claim
19 words
The retainer of claim 1 wherein the means for connecting is adapted to be embedded in the resilient band.
Claim 6
Dependent Claim
28 words
The retainer of claim 1 wherein spaced means for engaging the band attachment means each comprise a hollow, tubular section connected to the longitudinal extension of the body.
Claim 7
Dependent Claim
25 words
The retainer of claim 5 wherein the hollow tubular sections and the longitudinal extension are connected to each other at substantially a ninety degree angle.
Claim 8
Dependent Claim
23 words
The retainer of claim 6 wherein the band attachment means comprises a linear segment attached to the end of the tooth engaging means.
Claim 9
Dependent Claim
22 words
The retainer of claim 7 wherein the linear segment is formed at an angle complementary to that of the hollow, tubular section.
Claim 10
Dependent Claim
50 words
The retainer of claim 7 wherein the terminal end of the linear segment is adapted to be bent over one of said hollow tubular sections after it is placed over the linear segment, whereby the band attachment means is locked to the body to affix the resilient band in place.
Claim 11
Dependent Claim
56 words
The retainer of claim 5 wherein the spaced means for engaging the band attachment means comprises a plurality of hollow, tubular sections connected to the longitudinal extension of the body in longitudinal, spaced relationship whereby band tension adjustment may be easily accomplished by connecting the band attachment means to different sections of said hollow, tubular sections.
