Claim 1
Independent Claim 119 words
An intra-oral process for preventing spaced first and second teeth from moving together in the mouth including the steps of selecting first and second bands each of which has a projecting shelf formed thereon and placing said bands on said first and second teeth respectively with said shelves projecting outwarly from the mouth, selecting a spacer member having a body and extensions thereon and placing said body in the space between said first and second teeth with respective extension thereof on respective shelves of said first and second bands, fusing the ends of said spacer member to said respective shelves while in the mouth, and thereafter cementing said first and second bands respectively to said first and second teeth.
Claim 2
Dependent Claim 119 words
An intra-oral process for preventing spaced first and second teeth from moving together in the mouth including the steps of selecting first and second bands each of which has a projecting shelf formed thereon and placing said bands on said first and second teeth respectively with said shelves projecting outwarly from the mouth, selecting a spacer member having a body and extensions thereon and placing said body in the space between said first and second teeth with respective extension thereof on respective shelves of said first and second bands, fusing the ends of said spacer member to said respective shelves while in the mouth, and thereafter cementing said first and second bands respectively to said first and second teeth.
Claim 3
Dependent Claim 144 words
An intra-oral process for the preparation of a bridge between first and second teeth including the steps of selecting first and second caps each of which has a T extension from its incisal the width of which extends past the margin of the respective cap in both directions and placing said caps on said first and second teeth, selecting a third like cap and inserting it in the space between said first and second caps, so that the extensions of the T of said third cap respectively overlap extensions of the T''s of said first and second caps, bringing the overlapping extensions together into contact and welding said extensions together in the mouth, removing said caps from the mouth and welding at contact points between caps, smoothing said extensions and thereafter cementing said first and second caps respectively to said first and second teeth.
Claim 4
Dependent Claim 144 words
An intra-oral process for the preparation of a bridge between first and second teeth including the steps of selecting first and second caps each of which has a T extension from its incisal the width of which extends past the margin of the respective cap in both directions and placing said caps on said first and second teeth, selecting a third like cap and inserting it in the space between said first and second caps, so that the extensions of the T of said third cap respectively overlap extensions of the T''s of said first and second caps, bringing the overlapping extensions together into contact and welding said extensions together in the mouth, removing said caps from the mouth and welding at contact points between caps, smoothing said extensions and thereafter cementing said first and second caps respectively to said first and second teeth.
Claim 5
Dependent Claim 118 words
An intra-oral process for the preparation of a brace to extend between first and second teeth including the steps of selecting first and second bands each of which has a projecting shelf formed thereon and placing said bands on said first and second teeth respectively with said shelves projecting outwardly from the mouth, placing first and second buccal tubes on the shelves of said first and second bands respectively and welding said tubes to said shelves in the mouth, placing an arch wire in said buccal tubes and properly positioning the same by bending said shelves, removing said arch wire and said bands from the mouth and further cementing the bands to said first and second teeth respectively.
Claim 6
Dependent Claim 118 words
An intra-oral process for the preparation of a brace to extend between first and second teeth including the steps of selecting first and second bands each of which has a projecting shelf formed thereon and placing said bands on said first and second teeth respectively with said shelves projecting outwardly from the mouth, placing first and second buccal tubes on the shelves of said first and second bands respectively and welding said tubes to said shelves in the mouth, placing an arch wire in said buccal tubes and properly positioning the same by bending said shelves, removing said arch wire and said bands from the mouth and further cementing the bands to said first and second teeth respectively.
Claim 7
Dependent Claim 46 words
An intra-oral process for the treatment of teeth including the steps of preparing the tooth for receipt of a first appliance, selecting a second appliance which is compatible with said first appliance and attaching said second appliance to said first appliance by welding in the mouth.
Claim 8
Dependent Claim 46 words
An intra-oral process for the treatment of teeth including the steps of preparing the tooth for receipt of a first appliance, selecting a second appliance which is compatible with said first appliance and attaching said second appliance to said first appliance by welding in the mouth.
