Abstract
Abstract Orthodontic traction apparatus for applying traction to the teeth of a patient, including tensioning means for attachment to an orthodontic instrumentality on the teeth adapted to be stretched to apply traction, a neckband or headgear worn by the patient for anchoring the tensioning means after it has been stretched, and fabric fastening material for securing the tensioning means to the neckband or headgear while maintaining a desired traction force on the tensioning means, and the method of utilizing this comprising connecting the tensioning means to the orthodontic instrumentality, pulling on the tensioning means with a force-indicating gage until a desired traction force as measured by the gage is applied, and then securing the tensioning means to the neckband or headgear by means of the fabric fastening material while maintaining the pull on the tensioning means.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
218 words
Orthodontic traction apparatus for applying traction to the teeth in a patient''s mouth via an orthodontic instrumentality associated with the teeth, comprising tensioning means having means at one end thereof constituting its forward end for attachment to said instrumentality, and adapted to be stretched to apply traction to the teeth via said instrumentality, means worn by the patient for anchoring the tensioning means to hold it stretched, a fabric fastening element on said anchoring means, and a second fabric fastening element comprising a strip of fabric secured at one end constituting its forward end to the rearward end of said tensioning means and extending rearwardly therefrom, said tensioning means being adapted to be pulled in rearward direction to stretch it, after it has been attached to said instrumentality, by means including a force gauge for indicating the force thereby applied to the teeth, one of said elements having a multiplicity of hook-like pile elements projecting therefrom and the other having a plush-like pile surface for interengagement with the hook-like pile elements after the tensioning means has been stretched and while maintaining said selected traction force on the teeth thereby to secure said elements together with said tensioning means applying said selected traction force on the teeth, after which said elements may be permanently secured together as by stapling.
Claim 2
Dependent Claim
218 words
Orthodontic traction apparatus for applying traction to the teeth in a patient''s mouth via an orthodontic instrumentality associated with the teeth, comprising tensioning means having means at one end thereof constituting its forward end for attachment to said instrumentality, and adapted to be stretched to apply traction to the teeth via said instrumentality, means worn by the patient for anchoring the tensioning means to hold it stretched, a fabric fastening element on said anchoring means, and a second fabric fastening element comprising a strip of fabric secured at one end constituting its forward end to the rearward end of said tensioning means and extending rearwardly therefrom, said tensioning means being adapted to be pulled in rearward direction to stretch it, after it has been attached to said instrumentality, by means including a force gauge for indicating the force thereby applied to the teeth, one of said elements having a multiplicity of hook-like pile elements projecting therefrom and the other having a plush-like pile surface for interengagement with the hook-like pile elements after the tensioning means has been stretched and while maintaining said selected traction force on the teeth thereby to secure said elements together with said tensioning means applying said selected traction force on the teeth, after which said elements may be permanently secured together as by stapling.
Claim 3
Dependent Claim
24 words
Orthodontic traction appartus as set forth in claim 1 wherein said strip has means adjacent its rearward end for attachment of said stretching means.
Claim 4
Dependent Claim
19 words
Orthodontic traction apparatus as set forth in claim 2 wherein said attachment means compRises an eyelet in the strip.
Claim 5
Dependent Claim
101 words
Orthodontic traction apparatus as set forth in claim 1 wherein said tensioning means comprises an elongate tubular member, an elongate coil compression spring housed in said member and extending lengthwise thereof, a closure at one end of the tubular member providing an abutment for engagement by a respective end of the spring, said closure having an opening therein, a tensioning member engageable at one end with the other end of the spring and extending through the spring and said opening in said closure for connection to said orthodontic instrumentality, said strip being attached to the other end of said tubular member.
Claim 6
Dependent Claim
40 words
Orthodontic traction apparatus as set forth in claim 4 wherein said tubular member has its other end flattened and provided with an eyelet and said strip is provided with a hook at its said one end hooked into said eyelet.
Claim 7
Dependent Claim
19 words
Orthodontic traction appartus as set forth in claim 4 wherein said strip has slits for receiving said tubular member.
Claim 8
Dependent Claim
20 words
Orthodontic traction apparatus as set forth in claim 1 wherein said tensioning means comprises a length of narrow elastic fabric.
Claim 9
Dependent Claim
65 words
Orthodontic traction apparatus as set forth in claim 1 wherein said anchoring means is a cervical neckband, and said apparatus has a pair of tensioning means one for each end of the neckband, said neckband having a strip of material with the plush-like pile surface on the outside thereof, each tensioning means having a said strip thereon with the strip having said hook-like pile elements.
Claim 10
Dependent Claim
62 words
Orthodontic traction apparatus as set forth in claim 1 wherein said anchoring means is a headgear, and said apparatus has a pair of tension means, one for each side of the headgear, said headgear having strips of material with plush-like pile surface thereon at each side, each tensioning means having a said strip thereon with the strip having said hook-like pile elements.
Claim 11
Independent Claim
101 words
The method of applying metered orthodontic traction to a patient''s teeth comprising the steps of connecting tensioning means to an orthodontic instrumentality for applying traction to the teeth, said tensioning means being adapted to be stretched to apply traction to the teeth, pulling on said tensioning means with a force-indicating gage until the desired traction force as measured by the gage is applied to the teeth, securing the tensioning means in its stretched condition to an anchoring means such as a neckband or headgear worn by the patient while maintaining the pull on the tensioning means, and then removing the gage.
Claim 12
Independent Claim
101 words
The method of applying metered orthodontic traction to a patient''s teeth comprising the steps of connecting tensioning means to an orthodontic instrumentality for applying traction to the teeth, said tensioning means being adapted to be stretched to apply traction to the teeth, pulling on said tensioning means with a force-indicating gage until the desired traction force as measured by the gage is applied to the teeth, securing the tensioning means in its stretched condition to an anchoring means such as a neckband or headgear worn by the patient while maintaining the pull on the tensioning means, and then removing the gage.
Claim 13
Dependent Claim
94 words
The method of claim 10 wherein said tensioning means is secured to said anchoring means by cooperable fabric fastening elements, one on the tensioning means and the other on the anchoring means, one of said elements having a multiplicity of hook-like pile elements projecting therefrom and the other having a plush-like pile surface for interengagement with the hook-like pile elements for detachably securing said elements together, and wherein the method further comprises pressing together said elements to secure said tensioning means to said anchoring means while maintaining the desired force on said tensioning means.
Claim 14
Dependent Claim
43 words
The method of claim 11 further comprising placing a guard between said elements to prevent said hook-like pile elements from engaging said pile surface prior to attaining the desired force on said tensioning means, and removing the guard to secure said elements together.
Claim 15
Dependent Claim
27 words
The method of claim 12 further comprising stapling together said elements after they have been pressed together permanently to secure said tnnsioning means to said anchoring means.
