Abstract
Abstract An improved orthodontic positioner provides a series of tiny suction devices on the tooth confronting walls of the positioner. These suction devices provide increased adherence of the positioner to the top, inner and outer tooth surfaces of the patient's teeth, and act to mechanically hold the teeth firmly together in their desired place within the positioner.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
77 words
An orthodontic positioner for urging at least one of a dental patient's teeth from an actual position to a desired position, the orthodontic positioner comprising: a flexible mouthpiece formed to have therein impressions of the desired positions of the teeth; and a tooth-adhering portion comprising a suction device interior of at least one of the impressions for grasping a selected tooth and urging the selected tooth from the actual position to the desired position with suction forces.
Claim 2
Dependent Claim
77 words
An orthodontic positioner for urging at least one of a dental patient's teeth from an actual position to a desired position, the orthodontic positioner comprising: a flexible mouthpiece formed to have therein impressions of the desired positions of the teeth; and a tooth-adhering portion comprising a suction device interior of at least one of the impressions for grasping a selected tooth and urging the selected tooth from the actual position to the desired position with suction forces.
Claim 3
Dependent Claim
145 words
An orthodontic positioner comprising: a flexible mouthpiece into which impressions of the desired alignments of a dental patient's teeth have been made, at least one of said desired alignment being different from an actual alignment of at least one selected tooth, to be worn by the patient to urge the at least one selected tooth into such desired alignment by applying gentle pressure to the at least one selected tooth along tooth-confronting surfaces of said positioner; and a tooth adhering portion comprising a suction device interior of at least one of the impressions to increase the adherence of said positioner to at least one of said teeth, and more securely maintain said teeth within said positioner, the suction device being positioned to confront a surface of the at least one selected tooth and thereby urge the at least one selected tooth toward said desired alignment.
Claim 4
Dependent Claim
145 words
An orthodontic positioner comprising: a flexible mouthpiece into which impressions of the desired alignments of a dental patient's teeth have been made, at least one of said desired alignment being different from an actual alignment of at least one selected tooth, to be worn by the patient to urge the at least one selected tooth into such desired alignment by applying gentle pressure to the at least one selected tooth along tooth-confronting surfaces of said positioner; and a tooth adhering portion comprising a suction device interior of at least one of the impressions to increase the adherence of said positioner to at least one of said teeth, and more securely maintain said teeth within said positioner, the suction device being positioned to confront a surface of the at least one selected tooth and thereby urge the at least one selected tooth toward said desired alignment.
Claim 5
Dependent Claim
23 words
The orthodontic positioner of claim 1 wherein said suction device comprises a suction cup member presenting a flexible hemispherically-shaped surface to said teeth.
Claim 6
Dependent Claim
40 words
The orthodontic positioner of claim 1 wherein said positioner includes surfaces for confronting the top, inner and outer surfaces of said teeth and said tooth adhering portion comprises strips of suction cups carried on each of said tooth confronting surfaces.
Claim 7
Independent Claim
78 words
A method of manufacturing an orthodontic positioner comprising the steps of: providing solid reproductions of a patient's teeth; arranging said reproductions in a mold so they represent the ideal alignment of said patient's teeth; placing a plurality of suction devices on the top, inner and outer surfaces of said reproductions; pouring a flexible material around these plaster reproductions with said suction devices intact; allowing said flexible material to solidify; and removing the resulting cast from the reproduction mold.
